My interpretation would be that you would have to complete the motorcycle too and then take out the engine. (And don't forget to write the workshop manual.) Knock yourself out!
Thanks Randy
The GCR doesn't go into specifics as to what constitutes a 1,000cc 4 cycle Motorcycle engine. However assuming this would be a new build engine after year 2014 it would then need supporting dyno data and given to the CRB for approval.Quote:

Funny this thread came up. I once contemplated this very thing, something you can seriously ponder when you own a well equipped and modern cnc machine shop.
It would be fun writing your own shop manual, mine would be about 6 pages long.
The "Battle of the Twins" Daytona winner is probably too dated (despite its' excellent for 1995 engineering) at this point to be successful BUT, I have often wonder as a lifelong Ducati rider how a "DESMO" would do. I recognize the possible "packaging" issues with its 90 degree design but the torgue and crank design as well as the narrow engine with the ability to really "Coke Bottle" the back end of the car like a inline engine .................
I'm pretty sure you caught that I more meant how he did his own sand castings. There's apparently only one running Britten so you're never getting that 1L motor. However;
How far would you have to go? Reuse Gixxer internals and head just cast your own block?
Dimension your new block around the "Shaved heads"
Does that suddenly open your ECU possibilities? Maybe BMW instead then
Construct some variable intakes and drop it back in the gixxer donor bike for a "new york minute". Take photos, would you need video of you driving it? "Don't worry about that GSXR branding there on the tank it's not a gixxer motor"
Write your service manual about all the fancy things you ever wanted to have on a motor and how to service it
Show up on race day .... and ..... ohhh won't let me run.
But if you were inspired to get some fancy non-poppet valves working would that be going far enough to have earned a spot? Or am I still ruining the class?
That Smokey guy sounds like an awesome competitor. Pushes you to be at his level. Inspires your creativity through your utter frustration with what he'll show up running next. I like it
The reality is that it would never get past the CRB. It's written right in the rules anything built after 2014 is subject to approval with supporting dyno data. If you've got some frankenmotor that's a beast that you are naming XYZ they're going to look at it and laugh....if it did get past you'd have a small group of drivers complaining and we'd be back to same place we are at now.Quote:

Oh okay I see.
It's not simply dyno it and we'll get back to you with a restrictor or rev limit. It's dyno it and we can say no even though its an open engine class
Well you've touched on a very grey area of the GCR. The rules stipulate the engine has to be stock and stock parts used and stock specifications.Quote:

The engines aren't technically open, they must be stock. But stock for manufacturer XYZ and you happen to be XYZ manufacturer.
I guarantee this would cause a poop storm like none other.
I believe at the very beginning of the GCR it states "if it doesn't say you can do it then you can't" or something to that wording. That statement always made me laugh. Tell that to Smokey Yunick, dude loved gaming the rules.
It is not an open engine class.Quote:

There are tens of thousands of custom motorcycles in the USA. All you have to do is say this motor came out of my custom "2007 XYZ-built 1000cc bike"...at least for that month. I'm guessing next month there could be a competition adjustment putting a 10mm restrictor on that beast ;)
FWIW the current F500 MC-engine rules start off with this beauty:
"A. Mass produced water-cooled, 4 cylinder, 4-cycle motorcycle
engines up to 600cc are allowed as per spec line (end of section)."
One could argue the writers of the F500 class MC rules had different intent...or perhaps a little more foresight. Alternatively, one could argue that the FB rules are clearly more open in their intent. Motor has to be "stock" but who defines what stock is on a production run of 1 unit :)
I would suggest that the Smokey in you runs the motor only in tons of private test days and unveil it at the RunOffs before they slap a competition adjustment on it.
Like I said, I sense an E&O rule change coming.

There's still lots of single cylinder development to get the Bishop Rotary Valves to work. Company went under so finding seals is the issue.
The valves deserve a moment in the sun and all the RPM and valve longevity talk on here .... with rotary valves its bottom end longevity issues instead. And you have the RPM to buzz people by on the straights so you shouldn't HAVE to get close to the bottom end limit.
While on the SAE team i was chassis, suspension, steering. To learn more about powertrain i started to CAD a motor from scratch trying not to copy a motor but to work out dimensions so i understood better what's going on and why. It would be amazing to get my hands on some 2618 aluminum and make it
Companies like Ezcast and Exone can lend you their expertise on runner locations and foundry work as they cast your designs for you from 3D printed sand for about $1000/sqft last i asked around. But these days there's all kinds of DIY sites to make a PLA 3d printer. Which can be used like lost wax casting. How much accuracy do you need when you'll be machining afterwards anyway. 1/8" is fine you can design around knowing you might be out to lunch. But it's a 3D print and investment casting process so you shoukd acheive much better than that
Or perhaps a lot of hindsight. The original F1000 rules committee toyed with the idea of a minimum production # such that it would include the big four and preclude Ducati, Aprilia, etc. The problem was production #s weren't readily available.Quote:

He would just have made 3,001 then.;)Quote:

Since this seems to be a spending concern. What about leaving engines on the open side of legislation but a cost cap? Reward people who are creative with lowcost techniques? But gotta be careful with resale acting as a credit. Downside of this is you double guess every purchase you make. How to stop someone gaming a cost cap by buying things in his wifes name for market price and then buying from her for $1?
I donno. Me i want the freedom to explore but use restrictors and rev limits to keep em at 200bhp
Get yourself Ducati Desmosedici for about $70KQuote:

Remove the engines, sell all the bits. I am sure that you will have no more than $100K in the deal by the time you have the ecu, oil system, exhaust etc figured out.
Or better yet, build your own complete motor and come and race in FB. For sure we will see you in the next year or so.
Note that in the F500 rules engine table that only 3 engine brands are allowed.Quote:

The FB rules already define specific engines and model years in an engine table and this table can be edited or adjusted on a monthly basis.
Bring your dyno data and make sure that it is from a recognized dyno provider.
Aware of that and the logic behind it.Quote:

Like I said, I see an E&O rule change on the horizon. Or a "rule is adequate as written" attitude and the class gets "Tuckered" at the Runoffs at Indy or maybe it will be referred to as "Hickmanned" :).
What I said was that the table can be edited on a monthly basis.Quote:

Daryl, you may be right, but I am not certain. Does that ALL mean ALL ENGINES, AS IN EVERY ENGINE BEING PRODUCED NOW OR HAS EVER BEEN PRODUCED IN THE PAST? OR DOES IT MEAN ALL THAT ARE LISTED? Personally I think it means all on the list. Why list any specific engines if you mean all as in the totality of ALL?Quote:

Too bad every class seems to gravitate towards a spec class.
There are so many ways someone can be innovative .
An ingenious performance advantage should be encouraged. Makes for interesting diversity among race cars.
Like the quote on Arthur Mallocks shop wall supposedly said "The completion begins when the regulations are delivered".

Your right Daryl. I confused the old rule with the new rule.Quote:

Daryl;
Are you saying, because it says "ALL" ... show up with a dyno print and your one off motor and you meet the rules and its up to the CRB to ban your one off motor next month?
No, read the engine section in the GCR.Quote:

As to the dyno sheet requirement....that's only required on engines from model years 2015 and newer. I am sure the custom made one-off motorcycle based 4-cycle engine came stock in the 2014 ASS Special ;)
my apologies for reviving a 4 year old thread but, being as technology has advanced i thought to ask about another engine. Im looking to get into FB but want my own car and a different engine. If the rules state the engine must be stock and i feel i already have my answer but since its kind of a contradiction on the wording, the Kawasaki H2 996cc supercharged engine, I mean its stock it came that way right.
4. Engines
A. Motorcycle-based 4-cycle up to 1000cc.
B. Engine components (including cylinder heads and blocks) must remain stock, except as specifically
permitted in these rules. No material may be removed from any engine component, except as specifically
permitted in these rules. Valve jobs are permitted, but the valve seat diameter must not be
changed. The competitor must present, on demand, an original factory manual for the specific engine
make, model and year to allow compliance verification.
C. The stock or factory racing ECU shall be used. The ECU fuel and ignition maps may be changed.
Devices that modify inputs to the ECU (e.g., Power Commander) may be used. Stand-alone aftermarket
ECUs are not permitted.
D. Turbochargers and superchargers are prohibited.
Smokey read the stock rules as a "stock" Ford valve was legal, even if being used in a Chevy motor
FYI.........the North American Formula 1000 Championship has moved to SCCAPRO sanction......running with Formula Race Promotions. F1000 can and will grow at the pro level! Since announcing the move to pro, we are getting a lot more interest in the series. We have 21 cars registered for the series so far this year! Check out northamf1000.com for more details.
The series is using FB rules as of June 2018 (to avoid the throttle body/ecu controversy from the 2018 runoffs).but we are no longer subject to the crb rules interpretations. That task now falls to our series staff.
Be advised the series will be enforcing pure stock engine rules....,.including the throttle body and ecu that came with the bike from which the engine was taken. If you could order the bike with a "factory racing ecu" installed ......not one added after the fact.....then that engine/ecu combo is legal.
So......forget any wild engine tricks.....and yes we are considering min production numbers to keep the Tucker types from driving up the cost by building something special.
We are looking at the overall health of the class......and keeping cost down is part of that for most car owners.
F1000 is not a spec class. You can build whatever you want......as long as you use a stock bike engine. That has allowed many different chassis to be built. There is more variety in F1000 than any other formula class.....except possibly FV.
If you want to play with engine development, you can run your FB in FA or go run P1 or P2. F1000 is not the class for that.

Good idea. Wondering how you are going to obtain production volume numbers by model and year? I'm sure they've got to be out there somewhere.Quote:
