If this is the case, then it would appear that the Region in question did not choose the right spec tire. This subject was extensively discussed last year in the FF Nationwide Tire Suggestion thread, among others. A merely "hard" tire which still falls off in lap time after a few heat cycles is as bad as no tire rule at all.

Which brings me to the Toyo Proxes RA-1 mentioned in the second option in post #26 above, and which Quickshoe mentions a few posts above my Banshee post. During the run-up to SM becoming a National class, the Club had a tire "shootout" to pick the spec tire for that class, and the Toyo won hands-down. It was slightly slower than some other tires, but it was the energizer bunny...it just kept going and going with no drop off in lap times until literally the chords were showing.

If a spec tire is to truly save competitors money it must exhibit those two qualities. Otherwise, it's just a pointless exercise.

That just says to me that they don't have a R60/GY600 tire rule in that region.
EWC has had more competitive races in CFF, on R60's and NOBODY, put on tires for
every double race weekend. 20+ cycles for front runners was the norm.


R60/GY600 tire rule is a simple, available and immediate solution to tire costs in FF, besides making a slightly more equal field.

Jay,

What did you actually mean. I was assuming you were comparing a current FF1600 as raced (which is 1100) with an anticipated F600 as raced weight of 900.

Dick

The spec tire in question is R60/GY600. I know of other examples of spec tires not having the intended results. And spec tire was a failure when last tried in National FF racing.

If spec tires are the best this bunch can do, then I ain't going to fight city hall.

I was just hoping that there was a better solution.

I think unless you combine a spec tire rule (doesn't have to be one manufacturer) with a tire usage rule (ala FSCCA) you don't accomplish much. About any tire will be a shade faster when new & people with more bucks will do what it takes to win. period. Even the CF Hoosier R60 is faster when new.

I don't like the idea of adding another open wheel class that "targets" a specific group of potential drivers. I don't see a need to alienate arguably the most stable class in the Formula car run group.

Every winter we have the doom and gloom of the engine woes in FF. This year with having other discussion topics such as F1000 and achieving Zetec parity in FC we seem to have eluded that.

With the new engine components that are available for FF, why don't we work at addressing the other availability issues.

-What about casting new blocks?
-Weber carbs? How about the addition of fuel injection? Throttle body Injection (TBI) would be a simple affordable addition. Take it one step farther, new intake manifolds (intakes are in short order anyway) that could incorporate multiport injection. Performance changes? Likely, but it will not be difficult to reach parity between the updated injected setup to the current carb'd versions. We're not trying to overcome different internal masses, rod ratio, compression etc.
-Connecting rods

We need to adapt and be more modern, without having to do a $10k+ engine converison or lose more entries to yet another new class. I'd like to see us update and not obsolete 40 years of history.

We are discussing the topic because over the past 20+ years FF has dropped from more than 1800 National entries (more than all other formula classes combined) to a bit over 400 (a roughly 75% decline) and last year ranked third out of 5 National formula classes. If the Club adopts a policy of "benign neglect", FF may be gone in a few years. I know that there are many factors which have contributed to the decline of FF, and that there are counter arguments to my last point there, but the numbers don't lie. Over the past several years you can count the number of new FFs homologated with SCCA on one hand. During the same time period SCCA has issued at least one new SM logbook PER DAY.

Yes, I understand that the supply of blocks is becoming problematical. Not a crisis yet, certainly, but there is a finite supply out there. The challenge to getting more blocks cast is that I understand Ford destroyed the patterns some years ago and that it is too difficult/too small a market/too whatever for foundries to gear up to cast more.

The real answer is to gradually open up the class to other engine options. Look at the Zetec. It is a $15,000 investment, but one that more and more folks are considering worth the price. In its 170+ hp pro version, the engines go 9,000 to 11,000 miles between $3500 replacement. Who knows how long the mechanically identical engines will go at the 144-ish hp they are permitted in Club racing? Add a restrictor plate to a Miata, Toyota or Honda 1600cc stock motor and who knows how long one might last at 115 hp. Surely a lot longer than the 20 or so hours (40 hours?) that a Kent will go between rebuilds. So maybe a $10,000 alternate FF engine that goes 5 or 10 times as far between rebuilds as the Kent might be worth it.

Is EFI in FF a possibility? Sure, as long as folks are willing to embrace it and not treat it like a red-headed family embarrassment. (BWT, this holds for the Pinto in FC and S2, as well.) And rods are free so long as they're ferrous and meet the size and weight restrictions (p. 196 of the 2007 GCR).

Let me say again that having these discussions is both necessary and positive, because without them we may not identify problem areas and come up with solutions before it is too late.

Stan

What would it take to make the Kent last 8000 to 10,000 miles between builds? Regardless of what it does to HP etc etc etc. Internal mods, external mods etc etc??? What would have to be changed modified or whatever!?! Is it even possible to make that happen without getting too expensive? I am not an engine builder or fab man so thats why I am curious. I am still pretty new to FF and coming from shifterkarts and bikes so I am learning as much as possible guys!! :D

Answer:Less stress;)

Seriously, if you lower the revs, it will lower the HP (given the same torque) and will last longer. The issues then become enforcement and the costs of R&D that will be spent to increase the torque at that same lower rpm...

The question then becomes what do you mean by "last"? Are you asking what can be done to make the motor "last" longer without a component failure? "Last" without a noticeable horsepower loss?

I think great steps have been made, thanks to all those involved, to get parts manufactured and approved that will help on the longevity front. Those parts will eventually get stressed more (because they can take it), a new weak link will be exposed and other horsepower making wear items will have their life expectancy decreased.

ah ha.......club ford spec tires....that get changed frequently .....defeats the purpose......i'm the only one in the SEDiv years ago that voted against the CF spec tire rule......and watched the same thing happen here, people changing tires that yet had meat on them.....even though i did run one set all season....so i went back to FF and ran a lot of one-heat-cycle tires as much as 3 weekends and some free take offs......and won my class at some races, finished 3rd over all in SARRC in FF and won my region too. Hoosier never did, that first year, deliver on the promised purse either.

I'd really not care to run a hard FF tire when i'm on the track with FA/FC/FM etc .......why handicap myself just to have my mirrors more full more of the time? why have your budget dictated to you, when at the same time, you could have been faster too?

so in an effort to get others in CF SEDiv to have an interest to travel more [the excuse having been, "there's no CF down in florida, so why go?"]....and if you're reading this - see you in the 32F soon at maybe Roebling or Kershaw - an agreement was reached such that now the 32F is back in CF along with another car, even though i'd rather have stayed FF.....and so far no other CF have appeared.......the two floridians that registered CF for sebring has shrunk to one for lack of an engine.

qualifier rule? yes a multiweekend rule - that could be tracked via the log book - yes a choice of various spec tires? maybe

It is interesting that Stan posted a Picture of the $12,995 Banshee a few posts back. I've sat in the car, I've raced against it. I did not buy one, due to it being club specific, or being relegated to FS in SCCA. However the concept is similar to what I proposed at the start of this thread. Interesting point to note is that the Banshee can be run in CF/FF Power Tune, Or you can add the Aero bits (I don't believe one exists in this trim yet) and tune it to 150HP and be CFC Compatible. Same engine (Different state of tune) Same Chassis. Almost two cars for the price of one. A built in upgrade path is already factored into the initial purchase price.

I borrowed from this idea when I suggested that FD be powered by a restricted (but upgradeable) version of the FD legal power-plant. By using the same power-plants, the market for those supporting the F1000 Power-plant doubles in size. It allows for more healthy competition and reduces the spares inventory for suppliers and competitors. It also increases the appeal of the car, increases the size of the potential market. The car has an upgrade path to the next rung in the performance ladder built in.

How cool would it be to have FD & FD parts interchangable. Even items such are rear bodywork could be common between classed, making the eventual jump of an FD to FC Competitor easier.

Part of this comes down to marketimg. It is a common belief that wings & things are sexy. However, a winged car is not the best first race car. By offering FD in "Starter Trim", a form that can be upgraded without an engine swap makes the new car investment proposition much more attractive. For most of us, an engine swap (From 600 to 1000) may seem like a piece of cake (if chassis was engineered for it), but for newer participant, it can be intimidating.

Eliminate that intimidation by making the upgrade as simple as possible. One of 2 ways, Share engines between FD and FB or make sure that cars can be upgraded (From 600 to 1000 & Aero Bits) at a reasonable cost without re-engineering.

As for tires, the objective, IMHO should be that:

- they can last a full season a
- are hard enough that you can't take advantage of the wizzest suspension pieces out there
- are relatively cheap
- are common enough size that the mfg is not manufacturing them solely for a small class
- If rims & tires can be shared with another class(es) that would be ideal. Having class specific Wheel & Tire Sizes makes no econimic sense.

Good question, Andrew! Since my day job is to sit around and think about racing, I've actually gone around asking that basic question to several engine builders and engineers. However, if I screw something up in what follows, the fault is entirely mine and I'm confident those in the know will set the record straight. ;)

As Quickshoe notes, the stresses experienced in a Kent engine, especially inherent in the stock valve train at high RPMs, preclude a longer Time Between Overhaul (TBO). A change in valves and/or follower geometry might help skip the ritual "valve job" between overhauls. How far optimal parts can take us is an unknown to me, but rest assured that I will check into it.

Other big factors are the clearance of the piston package in the bore and the bearing clearances. Engine builders routinely set the clearances for main and rod bearings so wide that if this was your street engine you'd be rebuilding it to keep from blowing it up. Only the dry sump pump keeps the metal bits from banging together. Meanwhile, the piston runs with 8-10 thousanths (or more?) clearance in the bore in the name of lower friction. And the rings are set up with the loosest possible tension to minimize drag. All of that means that the engine is almost "worn out" when it comes off the dyno. It is a delicate balance to send the customer an engine that is loose enough to make good power, but will hold together long enough to make him feel he's gotten his money's worth.

BTW, this should not be taken as an indictment of the engine builders. They build what the buyers want and what the rules permit, while over the years the rules have evolved to permit building a hand grenade FF engine with mainly stock parts.

Don't believe me? Take a look -- no, read carefully(!) the FF engine rules starting on page 193 of the 2007 GCR. Notice that there is no maximum displacement? No maximum bore? Over the years the engine rules evolved from "throw a crate motor in it and go racing" to "who can be cleverest with the stock parts". As a result we get 115-ish hp from a motor designed to make what, half that? The downside is that it needs a costly rebuild every 20-40 hours, depending on whom one asks.

Now let's contrast that with the Zetec. The Zetec is installed as a stock, brand new engine. Its bearing clearances are probably half that of a Kent race engine fresh off the dyno. With a dry sump pump's good oil pressure that means the bearing won't see any significant wear for thousands of miles instead of in just a few hours. Plus, the pistons sit in the bores with only about one-tenth the clearance of a Kent's or Pinto's. That means they have higher friction, yes, but they are also more firmly stabilized and hence don't see much wear. Ring tension is normal, as well, for long life with low leakage.

The Zetec's head is better, too. There are 4 valves for better higher RPM breathing. And the geometry of the overhead cams has the benefit of 35 years of development from the days of the 1950's pushrod British econobox tractor motor in your FF. As a result the valves go straight up and down in their guides and don't pound out their seats.

To bring this conversation full circle, what could be done to the Kent to dramatically extend its life? Surprisingly, I think the answers don't involve a loss of power. On the contrary, it may involve an INCREASE in power, while still permitting a much longer TBO, perhaps as long as the Zetec's. Here's how I would go about it:

1) Set minimum main and rod journal diameters (and bearing sizes!) to tighten up clearances. That prolongs the life of the lower end, though it does cost a couple of hp.

2) Set a maximum bore diameter to close up the piston clearance to about 5 thou for forged pistons (less for cast). That would shave off a few hp but stabilize the piston, leading to less piston wear, and probably double the piston life. It would also lead to longer ring life.

3) Free up the rockers to permit roller tips or alternate geometry to reduce side-thrust loads. I understand that it is this asymmetrical loading that pounds out the valve seats. This also recovers a few hp lost by tightening up the engine in 1 & 2 above.

4) And finally, open up the valves to permit any valve of the specified maximum diameter, perhaps even increase the diameter to permit better flow. With this measure it would be a snap to recover any hp lost through steps 1 & 2 above. After all, the Kent readily makes 175-ish hp in its GT version without any sacrifice in TBO once the internals are freed up. Dramatically increasing its TBO while maintaining 115-ish hp should be easy. :D

Stan

From what I have read recently, engine reliability can be greatly increased in the Ford 1600/1800/2000 engines by changing out the rods, valves/keepers, and rockers with aftermarket parts designed for higher rpm limits.. And an increase in power can be obtained as a additional advantage.

I picked up a used 2.0l engine recently that I plan to build into a'cheater' motor for better reliability with a small increase in power to be used for solo and time trial events.

I would imagine the increase in life/reliability/power with aftermarket parts using tighter clearances would easily overcome the power increases gained with loose clearances that will decrease engine life.

The two largest cost drivers in a new FF are engine ($13,000) and gearbox ($8000). Shcoks are third, and may be as much as $6000. The key to reenergizing FF (and not merely "keep it alive") is to reduce acquisition cost for new cars. When looking for places to cut costs, you start with the major costs first. Ergo the look at bike engines and their combined gearbox if you are trying to figure out a way to reduce costs of a new formula car.

Regrettably, many of the folks that already own cars seem more interested in preserving their investment than changing the rules to encourage more participation. The very few folks who make chassis aren't making enough to replace attrition units, so the class will continue to decline UNLESS there are serious changes. If you want to keep racing the same few folks in the same few cars, then leave things the way they are.

Larry Oliver

I have spent the last year working on converting my FF to motorcyle power and hope to run it in FS this year. I guess you could consider it a possible Formula D car. I plan on running it in full FF spec except for the motor. I went with a 1000 motor since that would be common with the DSR's and the F1000 comunity. If a Formula D class was made I would rather have a restricted 1 liter motor to make the performance level similiar to FF as oppossed to trying to squeze everything out of a 600 cc motor. I would think you could run a restricted 1 liter motor for a very long time and that was my main goal (reducing engine costs) when doing my conversion.

Change is needed, that is generally agreed by all.

But the rush to MC power must be carefully looked at. 600 cc? Restricted 1000 cc? Open up the Kent to changes as discussed by Stan in post #62? Both MC and opened up Kent? Yeah, that needs to be discussed and researched also. Can both MC and Kent run together in a new FD class? Make the Kent slightly disadvantaged to MC power?

Lot's of questions. Not alot of research.

And importantly, can we make an engine change but maintain the current chassis rules? In this way, all the current FFs can join with the new FD class by making the engine/transmission swap regardless of the decision on engines.

Jim

Chris, during last year's discussion of alternate engines in FF the option of a restricted 1000cc engine was discussed. In the end, the majority wanted to stick with the unlimited 600cc option, but your approach remains very viable. I took this comparison chart from Sport Rider and plugged in the lines to show where 110 rwhp would be. Could you live with a rev limit of ~7500 RPMs? FYI, all of these engines make about 70 lbs-ft of torque at this RPM. Stan

PS - I meant to add that even though 7500 RPM may not sound as sexy as a 16,500 RPM 600cc engine, or even a 12,000 RPM FB engine, it isn't exactly tractor motor country. And all those wet sump/dry sump arguments in FB would be moot, as I don't think you could really hurt a bike motor at that low an RPM. It's not a bad idea...cheap, reliable and fast. ;)

http://home.earthlink.net/%7Erps1976...110%20rwhp.GIF

I could live with a reduced rev limit. This would help with engine life and hopefully help to equal the playing field between older engines and the new ones that come out every year making more power and more power at higher revs.

I've heard the engine/gearbox argument before and I'm not buying it. As Stan pointed out, it's the long term evolution of the rules that has led to what could be considered exorbitant engine costs. Had the FF community migrated to a more modern motor years ago and had the rulemakers been a bit smarter the engine costs could be much, much lower.

As archaic as they are in basic design, there's a lot to be said for the VW Type 1 style motor. Every part is available aftermarket from multiple manufacturers, so you have competition there. New head and cylinder designs have solved many of the problems associated with the actual VW design. You could probably build a decent pure-race Type 1 out of all aftermarket parts for $6K. There's also the fact that you don't need a water cooling system, and damage is frequently relegated to just one cylinder or just one side of the motor. Unfortunately, it's also probably just too close to being a FV. On the other hand if FV went totally vintage (horrors!) one could replace the whole FV/F500/FF entry level mess with ONE class, and if it was a modern, large displacement (2.0 to 2.3 L) VW design in a more modern chassis that would be a pretty interesting package.

A brand-new LD-200 in single unit quantities is $5625 using today's lousy exchang rates (not $8K), an FTR, which has the same external envelope as the LD but is MUCH beefier inside, is $9390. One has to wonder with the emergence of EMCO, Ricardo, Quaife, Pankl, and Elite in competition with Hewland and Webster, as well as Weismann, that there couldn't be a good deal out there if one specified a competiton for a mandated box.

I think shocks are probably the hardest item to both police and maintain cost control. Limit them to non-adjustable, and folks will just buy lots of shocks - that's what NASCAR guys do. Limit them to one type, and folks will get very crafty in cheating the shock llike in showroom stock. Maybe the thing to do here is spec a very simple, purely hydraulic shock that's easy to tear down and thus identify that the correct parts are inside - or - engineer a solution where the shocks aren't such a huge part of the overall equation.

The original FF concept had a junkyard motor. I'll wager one can buy a junkyard Zetec for much less than a bike motor - for no other reason than the fact that there are a lot more crashed Foci out there. It's true the bike motor is lighter and at a higher state of tune, but it was not engineered to go 100K miles. So a bike motor is cheaper than a race-prepped motor, but no way will it be cheaper than something built in the millions.

But the important discussion here should really be about something similar to the Banshee chassis concept, and overall simplification. Because of the relatively open rules of the FF and FC classes outside of the engines, The cars have become very complex. Complexity costs. Customization costs. Parts count costs. Take a look at a modern FF/FC upright and realize that none of the changes between that assembly and a similar item from 1972 made the racing better - it just made the cars lighter and marginally faster. Just look at floating rotors - only made necessary by trying to shave a few onces with aluminum hats. Besides the higher cost of the hat, there's $50/corner just in the special rotor bolts! That has little to do with learning to drive a more tunable chassis, they just shortend up braking distances some more, which makes passing tougher.

In order to reduce costs for the chassis - which is in actuality the highest cost item on the car - one needs to look at using parts from production cars where possible without getting into a matter of false economy by specing out something that is ill-suited to start with. Where production parts won't do then we should look at commonality with other types of racing - stuff like wide five hubs, wilwood brakes, etc, rather than re-inventing the wheel and optimizing it for our use. One could even have a limited, approved set of the major expensive parts that are cost controlled and awarded through competition. And lastly, one needs to look at techniques for lowering the fabrication costs in the frame - The amount of welding and hand-fitting is extensive - are there ways to reduce this? If one can't do that then offshore sources beckon.

This is one place where the dreaded Enterprises could actually help by being a broker to source parts at a higher quantity than any one manufacturer could do on his own, with limited pass-thru costs. But unfortunately, asking enterprises to support classes that might cut into FSCCA/Spec Racer sales would be a tough thing to do.

I understand that one way the designer of the Banshee reduces costs is to use Jetta/Golf front uprights on all four corners. That harks back to the early days of FF when as many parts as practical were sourced from production cars (the front uprights on my '75 Zink came from a Type 3 VW). A little "cleaner" approach might be to use Toyota MR2 or Mazda Miata uprights. These photos show a Solo II A-Mod that used all four uprights from a Toyota MR2, complete with the entire OEM brake package. Here is the front right corner.

http://home.earthlink.net/%7Erps1976...%20upright.JPG

The rear of the car has a spool with half-shafts from the MR2 going out to MR2 rear uprights.

http://home.earthlink.net/%7Erps1976...%20Upright.jpg

Nice clean design. One could do the same thing with Miata parts even cheaper today, and they would be just as good and are a lot more widely available.

Stan

Rick;

You make some good points.

From my perspective some of you points are not quite valid but only because of new realities of manufacturing. With modern CNC equipment we can make parts for way less than we can aquire and modify production items.

When I started building FFs we used a large number of production car parts. When I was doing Z10s I was able to use front uprights, brake rotors and claipers, the entire rear drive line from the transmission to the wheel from a late model Bug abd Fastback. For the Z16, I used Spindles, bearings, rotors, and the entire drive line from the trans out from a Rabbit.
Swift used a lot of VW parts as well.

Some production car parts that look adiquate going in prove to be problemetic over time. The spec racers had some problems with stock components and Swift has problems with some stock components. Today some of the stock components we used in the Z10 are no longer safe to use. And ICP builds VW rear brake drums for the same reason.

Over time we were able to make our own parts that were a better fit at a lower cost. Today, it is less expensive to build what you need than adapt production parts. The brake rotor and aluminum hat deal came about because the alternative was no longer available.

Having just finished a new FC, I have a good idea about what it costs to do cars in the volume that SCCA racing is likely see.

Years ago in England, formula Renault started with what I thought was a good idea. Renault sold a box of parts from which you made a race car. This is what FV was/is, a race car built from a box of parts. In the Renault box were engine, transmission, other dirve line and components. The manufacturers then had to build a car using the parts.

Another idea, that would not involve a large investment, would be for some "group" to come up with a standardized design for major components such as uprights, bell housings, and other drive line components. The drawings would be published and you would build a race car and incorperate standard design components. Let the market decide if every one wanted to single source the various components, maybe get them built in China, or every builder do his own. But the parts would still be interchangeable. Stock racing is somewhat like this, in that many of their suspension components are interchangeable with early Camero.

Stan: Some of the stuff in those pictures might be a little marginal if you were to up the tire performance very much.

Several have asked why the bike engines.

To answer that question, look at the success of bike engine powered race cars. Legandscars, dwarf cars, mini sprints, just to name a few.

Look at what the 4 cylinder, water coolde bike engine has done for DSR. a decade ago the class was on the chopping block. Along comes a good source of engines as well as production cars that are reasonably competitive and prices about right. Recently the class has enjoyed a resurgance because Lee Stohr was able to market a better car that was a winner available to all. Not only that, the performance of the DSR became impresive.

After I spent a year working with a Stohr customer, I became sold on the MC engine package. I just hate leaning over fenders. Thus I have become a big fan of MC powered formula cars.

Yep...I wouldn't want to circuit race those a-arms! :D

Steve - I knew the CNC thing could throw a monkey wrench in the economics - that's why I'm as much in favor of the "box of parts" concept as the "production parts" concept. Standardize and simplify the uprights, hubs, rotors, bearings, halfshafts, and calipers and there's probably a 50% savings per corner over everybody doing their own thing.

What can be done with the basic chassis? Is it possible to reduce costs by going to fewer, square tubes with simple, flat stressed composite skins? Maintain the repairability of tube frame while getting some of the stiffness and safety of a tub car without the long term problems of tub cars in a club world.

One thing that keeps me at arm's length on the bike motors is the lack of a consistent supply. With car motors, when it's time to re-build, it can be re-built at reasonable cost. If it's cheaper to replace, there's certainly a pile of them in the junkyard. But let's say in 2018 I buy a 2008 FD wirh a 600cc bike motor that was retired to a barn with a soft motor. My options are now to re-build the bike motor (potentially as expensive as any 4-cam race motor re-build) or to integrate a completely different 600cc motor - a much larger task even if the chassis easily acommodates it, and not something the entry level guy might want to tackle.

Another point, but harder to measure, is if americans keep maiming and killing themselves on these things sooner or later the insurance companies will speak loudly, and the supply could drop dramatically.

This is Deja Vu all over again. Access the F1000/FB threads. Same song different band.

Deciding on spec tires isn't going to reduce the cost of racing. It simply means someone will put on new spec tires every race (even if there's only a 5% difference between used and new - they'll do it!) - AND, spend the same amount of money to win, just in different areas. Maybe the cars will be so spec that the extra funding is spent on driver coaches and motor coaches, and gazillion dollars trailers, etc. Do we have spec trailers next? We've already seen a thread in the F1000 section where people are worried about the "new" motors that will produce more power. I know Sean says his motor cost will be $375 a year. No offense, Sean, but I doubt that will provide a motor tuned to the limit of the rules. Someone will pony up for several brand new Dean engines every year. I'll say it again, there is cheap racing. There ain't no cheap winning.

To say FF is no longer an entry level class is, IMO, bollocks. An entry level class, again IMO, provides a safe and relatively inexpensive venue to learn the craft and develop the skills. It does not have to provide for being nationally competitive from the get-go. Used FFs are available for a lot less than $25k. Complete setups with trailers and support equipment. Are they as fast as the top-o'-the-line current cars? No. They ain't supposed to be. So. please don't say there are no opportunities to get into the open wheel sport for reasonable costs. At that level of racing a Kent motor can easily last two years (or more) with only head freshening. The costs do not have to be as high as are touted. They can be - but they don't have to be. And, that statement can be made in reference to any class either conceptual or extant.

Plus, I happen to agree with those that see any such move as a direct threat to FF and the rather extensive investments in time and money many loyal racers have made. Any new class in this area will irreparably harm FF, just as we'll see (IMO) FB hurt FC.

Until I saw an F1000 in action for the first time, I was in the camp that these are race cars and race cars are powered by car engines. However, after seeing and hearing one of these in action, I've become convinced that MC engines are the way to go. Sex sells, The MC Engine in my opinion is higher tech, almost has a F1 (sexy) sound, especially with a semi auto transmission. Make the package easily upgradeable to FB trim (adding the extra the sexiness factor of wings) and you have a very marketable vehicle.

I also like the smaller packaging of a MC Motor. It would be nice to have most of the engine/trans spares in my trailer replaced with a spare engine/tranny and a selection of sprockets. The unit is small enough to be manually handled by two people. Small enough to fit in the back of a mid sized SUV. Easier to ship for a rebuild (or to second owner if rebuild does not make economic sense).

Question: Does it make sense to base a class on junk yard sourced motors? I don' think that is wise as the Supply may not always be enough to meet demand. Question not only applies to the MC engine but any Auto engines being considered. I know that Banshee went the route they did, since all the components are avail via multiple sources, as new. No junk yard donors needed. Nice to be able to drop an assembly line fresh motor into a new car.

Are any of the engines under consideration avail as new? Will they be avail as new long term? Not that new sourcing is a deal breaker, but it is nice to have that option, should used power-plants become unavailable.

I believe if a $5000 Engine/Tranny Combo is made avail, the manufacturers are starting on a firm foundation to bringing a moderate tech, reasonably quick, modern open wheeler to the market for low $20's. At that price, I believe they will find buyers, in particular if the package is upgradeable to the next level for reasonable cost. The club gets the entry level class to attract the Karters and first timers. These folks, hopefully will be life long contributing members, helping to keep the open wheel spirit alive.

As an alumni of several FSAE cars. I would love to see a 600cc bike motor powered, no wing class. Please make it compatible with converting a FF(as I do not believe FB is compatible with FC without major aero upgrades), even keep the FF wheels, track, wb, everything.

I'll be the first one in line to build one.

As for spec tires- let the people who know more than me decide.

Stan: For sure, but the attachment points wern't much better.

Rick:

The basic frame is not a big cost item. Example, I am selling my frames for $4000, fully welded, with all the suspension and engine frame mounts. But the customer would have to pay me another $2000 to add all the finishing details. That $1000 to $2000 would be involved in any frame no matter how much you simplify. The labor to complete a car is the killer.

The best way to calculate the cost of a car is to count the number of joints and multiply by your shop rate. Then take the weight of the frame and multiply by $2 to $3 for the material cost. Joints in round tubing are actually easier to make. Welding is done by the inch. Square tubing is a lot more inches of welding.

Tube frames have proven to be very durable. Look the age of some FF frames. I am selling parts for cars I built in 1974 and those cars are not really old by FF standards.

Most of the recient designs of FF/FC have detachable engine bays. This makes changing power plants easy. If F600 sticks with FF rules, then we already have a good supply of entry level cars for F600. New cars will be added at the top end but in time they will shift down in cost to provide good entry level cars.

The bottom line is that this is all hand labor by highly skilled people making reasonable wages. Until you have done it you can not imagine how much labor is involved in building a car. Rebuilding a car is nothing like building that same from new parts. In a new car, I guarantee that nothing fits exactly right the first time.

You buy a new Stohr F1000 "turn key" and you may spend several thousand getting the car to a truely race winning car. There is no way that the customer car can ever be delivered at the same level of preparation that goes into a national championship winning car. If you were honest that level of preparation might double the price of the car.

As to engines: in todays marked and it has been true for some time, new engines have been equal to or cheeper than rebuilding. It is also true that the bike guys rebuild all the time. The one thing about basing a class around current bike engines is that the engines will evolve as the bike market changes. The thing that is killing FF and FC is that there was no painless way to change engines. Today you can buy a brand new F1000 engine for less than a rebuild on a Pinto or Kent engine.

As optimistic as I like to be I don't believe we will ever have more FB's or FD's than squids who wad up bikes. Add in the guys who buy and strip them... I don't think supply will be an issue.

I posted a link to an Ebay add for new GSXR600s for $1700. These were 0 mile motors. I know Matt and others believe a builder should go through the motor but I know guys (I'm one) who beat on them for years (just stockers) w/o any issues. The issues arise when lubrication is lost or they are built to beyond design.
I've down-shifted accidently 2x in a row resulting in 14,000+ rpm w/o throwing a rod. These are robust little motors.


I believe the main issue in a class designed for cost savings/ entry level racing is tires as others have eluded. Crack that nut and your on the way.

(BTW- I know I'm going to be at a disadvantage w/ my 04 motor. I've also got a 11 year old car! So what? I raced an entire season on a set of 8 & 10's. I raced an entire season on a used motor... and was fast. 98+ VD fast. Thats about $1,000 for tires/ motor/ trans for a YEAR. There's your cost savings.:D )

I'll also throw in a vote for the durability of these motors. I've seen multiple people learn to drive a clutch on one, no problem. Ours last for dozens(50+) of dyno pulls, then the chassis dyno, and then lots of hours driven by people who have no clue. We tore the pan off of one in a crash, shut the motor down afterwards, put a new pan on, and it ran.

We usually expect to pay about $1000 for a used, low mile 600cc CBR600F4i motor. You can do better if you are willing to wait, or strip one out of a bike.

I'm interested in how feasible it would be to buy a new bike, ride the break-in period, and part the bike out. Plastic is very expensive, so I think it might work.

Or a vee engine. My last vee rebuild was around $2500 with shipping both ways(and the builder ate the cost when it wiped a lobe on the cam on the dyno, and I took a 20/20 crank to save some money too). One of the biggest bike junkyards in the country is only a few hours away, I could save a considerable amount on shipping, could probably scam some free stuff out of them too, they're good guys.

I'm having trouble seeing how this class couldn't be cheaper to run than a vee. Crash damage would clearly cost more, and the shocks would be another expense.

Steve - I was making my assumptions based on the replacement cost of a current VanDiemen frame - which I believe I saw on their website at $12K! Your costs certainly turn that assumption around. I have mine torn down to the bare frame right now, and when I took it over to my painter he took one look at it and said "holy sh!t - look at all that welding!" I saw an article on the Stohr use of stressed flat panels and i thought that maybe that was a much cheaper way to go. The front bulkhead on a Van Diemen is extremely complex as a fabrication, but I wonder if you couldn't just wire EDM the thing out of 1" plate and be done with it if you weren't extremely concerned with weight. It does look like other manufacturers have found better ways to fab that area.

Several years ago I worked with Manny Papendreas on a Turbine engine for a missile. He taught me all about production cost being a direct linear relationship to parts count, and since I've seen that in just about everything (and a single line of code counts as a "part"!). Every part has to be fabricated, tested or inspected, and assembled, so it's all touch labor - thus my "parts count and simplicity jihad".

I agree that it's currently cheaper to buy a new engine rather than rebuild a kent or pinto, but thats as much a function of the rules and state of the art as they evolved as anything else.

It is true that the life of ANY engine in ANY class nowadays - be it a bike or automotive engine - is much more limited. Due to CAD/CAM, rapid prototyping and other manufacturing techniques, it makes more sense for the manufacturers to re-optimize every time a new model is introduced or the emissions/CAFE requirements change, rather than to build a single motor design and constantly adapt.

If you were to sell plastics off of a new bike expect to get around $800 to $1000. They really do go for a good amount. All of the race guys would like to have have a roller set up on the bike. I am not for sure how much that would go for........but I would think you might get around $1500-$2000 for the roller chassis............

Andrew

I just wanted to chime in a bit on the MC engine durability issue....these are fairly durable motors in their stock trim...built motors with aftermarket pistons and machined decks and heads...another story....when valves and pistons collide...bad news.

Even though I would like to see it...I don't foresee any MC manufacturer getting behind what we do to their engines....forget the fact they come from crashed bikes....

I thought West was buying (and selling) crate motors from Muzzy? Are these new motors from Kawi or wrecked bikes?

Anyone know what the approx price differance is (Apple to Apple onparision) between a 600cc and a 1000cc (as used in FB) engine would be?

From shopping Ebay on nearly a daily basis for a year or so...
Figure $1500-$2000 for a new 600 and $2750-$3500 for a new 1000.

Used motors are quite a bit less even if under 1000 miles. $500-1000 for a 600 and $1000- $2000 for a 1000.

I paid $2500 for my 1st motor (picked it up) a 0 mile 04. The 2nd one was $1500 shipped but had 2500 miles.

Ebay is not your only source... there are bike salvage yards, builders, and a little company in Arizona.

Here is the rule book for the Championship Cup Series. I ran with this organization when I was racing bikes. When I was racing in the 600 class I ran in the middleweight supersport class and middleweight superbike class, and of course you could always race up in the the liter bike classes as the 600's were as fast if not faster at most of the tracks here in the midwest. Unless of course we were at Road America........This rule book gives you guys an idea of what they are allowing in the engines.

Ok, so after 4 pages of discussion there seems to be a good basis for the rules of the class. I know from all the reading i'd probably buy one if this class comes out, maybe even convert a current FF. The only problem I see is who's going to build the first FD??

The key words in this whole discussion (at least to me) are "Entry Level". From somewhere up above:

Quote:

---

The two largest cost drivers in a new FF are engine ($13,000) and gearbox ($8000). Shcoks are third, and may be as much as $6000. The key to reenergizing FF (and not merely "keep it alive") is to reduce acquisition cost for new cars. When looking for places to cut costs, you start with the major costs first. Ergo the look at bike engines and their combined gearbox if you are trying to figure out a way to reduce costs of a new formula car.

---

If you want entry level, to my mind the car costs need to be in the range of new F500 cars ($20-25K for a complete car.) Definitely not north of $30K. Within a few years used cars will start filtering down. When I was looking at getting started in Club Racing I looked at FFs and what convinced me to go with an F500 were the engine, transmission and damper costs. I decided to go F500, but that's not for a lot of people (something about "oversized go-carts" comments comes to mind. ;) ) But for entry level, I think that about the price point you have to hit. And the engine overhaul costs need to be kept in check somehow. Simple language in the rule such as, "Engine as manufactured by OEM. No component of the engine may be altered, modified, or changed nor be of any other origin than the original equipment manufacturer (OEM) unless specifically authorized in these rules." Then severely limit what is authorized in the rules.

Once again, the key words are ENTRY LEVEL!

So I sell my DSR this winter because a revised interpretation by the CRB of an age old rule with a very clear intent renders my car uncompetitive. I buy a FF because I am looking for something with stable rules, reasonable cost and low maintenance and here’s what I walk in to.

The only one that has actually summed up reality is Charlie Warner on page 3. If you want to know what a FD would really cost then look at the cost of a new F1000 from Stohr or Phoenix, it’s the same car with the same number of parts. Subtract $1500.00 for wings and maybe $500.00 for a supposedly cheaper motor and where does that leave you for your entry level car? Keep in mind these prices will only go up from there as the need/want for these companies to make money kicks in. Or look at a VanDieman roller, again same car, same number of parts. There’s a reason they cost what they do. The only way to make it cheaper is to have fewer parts. We already have that in F500 but for some reason that’s unattractive even though it meets all of the cost goals you seem to want. And yes, you can make something like the Banshee, but the minute you do, someone like Stohr will come along and build a rocket ship and blast it off the planet.

For those that think the motorcycle engine is the answer to everything, it is not. They are a whole lot bigger pain in the butt than these posts would lead you to believe. Does anyone really think you can win in a truly competitive class with a $1500.00 junkyard motor? A crate Spec Miata motor costs $1500.00, but look what they really end up costing and by the GCR that’s a so called “stock” motor. The only reason a FF or 2 litre cost what they do they do is because we are literally squeezing the last single HP out of them. The same thing happens in every class. I’m glad to be done with motorcycle power. They sound and feel great but they are not cheap, not overly reliable and certainly not low maintenance.

The biggest problem I have with this deal is all I hear is how we are going to consolidate the formula car classes into A,B,C,D and V. That’s great, but you already can’t get that done. How is creating more classes going to help get there? It’s not; it’s just going to make it a bigger nightmare when and if it ever happens. At every turn we make what needs to be done for the long term more difficult. Or maybe that’s just where we’re going with our club. We’ll have 12 different formula car classes so everyone can get a $3.00 trophy. Change our name to the “Track Day Club of America”.

FF has survived all these years because of the stability of the rules, not in spite of them. And no, the class isn’t what it was in its heyday but it is unrealistic to think it will be again or for that matter that any formula car class ever will be.

Also, can someone explain to me how it took years to get a new crank and flywheel approved for FF but we can have a new class in a matter of months? Something is wrong with the system when the priority is creating new classes versus helping existing classes.

Personally, I wouldn't mind FF going back to DOT tires with an open tire rule (so SCCA can’t sell it out like they did with Spec Miata). It will never change the outcome or cost to run at the front, same people will spend the same amount of money and the end result will be the same, but I think it would tighten things up a little.

I won quite a few DSR Nationals in the SE and NE between 2000 and 2003 with a cheap junk yard Yamaha R1. It definitely can be done.

I plan to kick some serious F1000/FB tail with a box stock GSXR later this season. I have put my 'skin in the game' repeatedly. I ran FF with a late model Van Diemen in 1998-2000, ran Stohr DSR s/n 001 from 2000-2003, ran a Zetec car championing it's inclusion in FC in 2004-5. This weekend I bought a 1999 Van Diemen with 2003 updates and I am converting it to F1000 specs...

What I can tell the uninitiated is that:

1) FC/FF Pinto motors really SUCK!
2) H-Pattern gearboxes - SUCK!
3) Yes Virginia, you can run salvage motorcycle power and win Nationals and run top 5 at the Runoffs. I have done it, and I am not that good.
4) Until you hear a m/c powered car pass at 12-13k RPM you haven't lived.

Bring it on!

Sean

Amen, Sean.

The sky is not falling....

I won a lot of nationals too in a home built DSR over the last couple years. I really don't consider that an accomplishment.

You've also missed the point. This isn't a discussion about F1000 or DSR. It's a discussion about creating a new class that specifically targets an existing class. IMHO, something that is fundamentally wrong.

It also relates to where we want to be as a club in 5 or 10 years down the road with formula car racing. Do we want lots of classes with watered down competition across the country so everyone gets a trophy or do we want to funnel things down or a limited number of classes with stronger competition. Clearly 2 different paths to take.

This year I am getting my 2 teenage boys in the car. My choices to do that were Spec. Miata or FF. I chose the ford because it had the best balance of cost, competitiveness in the division and maintenance.

Bill;

The days of single car racing groups are long past. Now everyone is looking for the racing class that will catch on or a run what you brung class structure. Cheep obviously isn't the answer or F500 would be the biggest class.

My opinion is that Zetec FC is the best bet currently and will have the lowest operating cost over time. The only part that may not be as durable as could be is the transmission and that can be solved. The only black cloud I see is the issue of the aluminum head Pinto. If the Zetec emerges with a tiny advantage, then the Zetec FC will be very stable as a class. If the Aluminum Pinto has the edge, then the benefits of a super durable engine will be lost. With the aluminum Pinto car owners will face major rebuild bills annually.

FF has chosen to not change and continue to exist as is. For the next 5 or so years, I think that is a good choice. The problem is that there are no new cars being built. If we get F600 with a FF type rules set, then that problem may not be an issue because there will be volume production of cars that can be built as FF. I am betting that I can make a standardized product to serve FF, F600, FC and F1000. I may not win that bet.

The advantage of the bike engines is that they offer great performace for low bucks. F600 and F1000 will suffer from the annual engine upgrade. If engines have a 2 year service life, then compared to the current FF and FC Pinto you will be money ahead. Also we are running the MC engines stock unlike DSR.

It still remains to be seen if F1000 gets up to the numbers to make the run offs any time soon. I was active in getting the current FC/Pinto cars to the National Championship level. That took about 3 years but we had a pro series in Canada at the time and you could get used cars from England at very low prices. F1000 is a stand alone deal.

Over the next couple years, F1000 will do a lot of sorting through designs as every one tries to find the best combination. At the same time the participation numbers have to get high enough to qualify for the run offs. I think this will be a lot of fun but any one who thinks that they are not in a development class better take a better look. Any one who doesn't like the thought of having to change their car to keep up better think again. It is highly likely that when we get to deciding a national champion, all the cars currently being marketed will not be competitive.

Just wanted to say how much sense Bill Johnson made ...

See post #56 and Stan's #62. There are ways to cheapen this motor tremendously. But even if there is no future in the Pinto motor, let's not disenfranchise a huge group of car/engine owners. Let's not create a MC FD class in addition to the current FF class. Combine the two. Equalize the best we can, accepting that perfect equalization is not going to happen.

Here, here! The continual addition of classes with great frequency is taking its toll. Time to stop this reckless lack of vision. Let's take a holistic look at the formula category and lay out a long term plan for all its classes.

No Bill, IMO that question can't be answered. Not with any reasonableness anyway.


As for FC/FF Pinto motors and H-Pattern gearboxes sucking, whether that is true or not, it would be wise to check the rush to MC power (for F600) and take a long look at it. Yeah, the MC engines are neat, and having them scream past at 13k is cool. Is that what we should base this decision on?

Jim

Sure would like to know if the motor mount dimensions are the same on an R1 compared to the 600.

And how much lighter is the 600?

And how much SMALLER is the 600?

And where are these 0 miles engines coming from?!

Thanks. Bill Hiatt

I just dont understand why everybody wants to drop everything we have and go to F-1000 and the non-existent F600. Does everybody that wants one of these cars going to go out and buy one for $20,000-30,000 as soon as they come out? I know I cant! I would be lucky to get $10,000 for my whole ff setup. The reason we got into FF is because we were spending some big bucks to race shifterkarts on the national scene. My dad and I said this is ridicoulous lets get a car in SCCA and do some club racing. I know that my income wouldnt allow a $20,000-$30,000 car even with the help of my dad. I guess what I am saying is we have FF racers racing and we have FC racers racing. Lets help the too many current classes that we have. I think it would be cool to have a F600 screaming at 16,000 rpm but............................................... .are we just in the silly seasaon still?:D :o

Andrew

The FF crank shaft issue involves SCCA Enterprises.

There was a crank built, tested, and that really fit years before Enterprises had theirs available.

Whats more, that crank would have been available for about half what Enterprises charges.

Unfortunately cars cost money. The prices that Stohr and Phoenix are asking reflect the reality of building cars in the US today. Almost any type of car is going to cost about what you see.

Some one might be able to get a car built in Mexico or China cheeper but you will need volume sales and right now there is no assurance that the volume will be there.

This is the delema that leads to the spec car idea. Problem with spec cars is that the only thing spec about spec car racing is the cost of entry. You don't get the price structure you have in FF and FC with cars going form under $10,000 to over $50,000. You can have a good serviceable car at many different prices. You can also buy second level cars and through good preparation and good driving still run at the front. With spec cars you get one price for all.

For F1000 you can convert cars and if there ever is a F600 those cars that don't make it as F1000 will certainly be good F600 prospects.

The real discussion should be about the cost of playing at any level. F1000 looks real good to me. And F600 could be even better.

Go back and look at what the old FM cars cost. Something like $35,000 I think.

Folks that is the cost reality.
