Okay, then I guess I must be the only person who ever thought about reducing their oil temp by having the gears coated with a micro-thin lubricant. It was worth about 15 degrees and 2 horsepower (we...

I've got no oar in this water other than curiosity, since our cars aren't legal for FB anymore, but here's a thought.

All of this angst is about trying to shift a stock motorcycle gearbox faster...

It was also inaccurate. Have you considered that a modern DOHC motor that has cams acting directly onto buckets on the valves has exactly the same unidirectional wear pattern as a pushrod motor? ...

There is an interesting precedent for the open ECU's in racing right now, as there are a number of 2010 cars whose ECU's persist in going into a limp-home mode when subjected to racing conditions. ...

When we first received our Stohr F1000 it would pump water out like crazy (this was a dry sump motor with an electric waterpump). I was getting really good at replumbing it between practice sessions...

Boy, if you had trouble at T-hill, don't even think about running at Laguna Seca! Most of the cars that I have worked on have no problem at T-hill but have lots of problems at Laguna; one car wound...

True enough for the tube, but not necessarily true for the weld that is attaching it, or for the part of the tube that was welded on for the attachment.

I wasn't there today, but I'm glad to see that Phil DelaO's engine problems were apparently permanently fixed by the dynamic due of Mitz & Dean. I'll look forward to the details of the Sunday...

I believe that Woodman (Stohr) was 3rd and delaO (Phoenix) was 4th. Eight FB cars started the race.

DelaO was plagued by an engine problem that was apparently solved just before the Saturday race...

Having a inline turbo Hayabusa-powered Super Production car with a driveshaft and a quick-change rearend, I would have to add that most of the adapters to connect driveshafts to motorcycle...

What's going on here? The entry list as of 3/10 only shows four FB's??? I was looking forward to a big turnout and a great race!

Marty

I'm with Nicolas on this one. We have tried calibrating the AIM dash with the 07 engine not running, and the values change when you start the engine. We then tried calibrating the dash with the...

Matt,

I'm glad to hear that you didn't get derailed by all of the smoke coming out of Topeka. I look forward to your progress with the 07 prototype, and I am anxious to see that snarky 2009 model...

Okay, I'll tackle this one. Here in the San Francisco area we can run one National that is local, then spend the rest of the year driving to southern California, Oregon, Washington, maybe Las Vegas...

We ran one for a couple of years when we had to remove the alternator for a trigger wheel on our Hayabusa-powered Super Production car. We just added a V-pulley to the driveshaft adapter from the...

Ours was the other F1000 at Infineon this last weekend. We qualified mid-pack, ahead of a lot of FE's and FM's, and proceeded smartly from there. Our driver improved his laptimes dramatically...

If your fuel line is rated at 200 PSI, it is EFI line. Back in the old days of carbs, fuel line didn't have to deal with more than 7-15 PSI. A line meant for those pressures would have a rather...

Unfortunately, it looks like we are going to have to scratch this weekend, due to some issues not related to racing.

Damn, I was looking forward to seeing Don with some decent competition in FB...

The latest Accuweather forecast now shows partially sunny through Saturday and just 1 hour of light rain Sunday. Can't tell yet if the rain is during the day or not.

Marty

Since so far this seems to be a Stohr FB race, what is the consensus about the front wing rule? Is everyone going to change to flat endplates, or all run the OEM endplates and agree to ignore the...

Don Madsen will be there with the GonMad Racing Stohr.

Marty

Wayne at Stohr just sent out an advisory to all of the Stohr F1000 owners pointing out that in some high temp situations they have found some heat damage to the back side of fuel cell bladder due to...

I have no objection to the clarification, but it is a shame that it outlawed the car that is the highest percentage participant in this class. I know that we don't really want to have to buy a new...

It appears that the rules clarification has outlawed the factory front wing that every Stohr F1000 was delivered with. Don has already written the CRB complaining about this; have the rest of the...

I wonder how wide our front Stohr F1000 wing is, as I would assume that those cute little winglets at the bottom of the endplate would have to be included in that dimension ......

Marty

That's kind of an odd relationship you have between the pressure and scavenge lines; normally the scavenge lines are bigger, since they are pumping an air/oil mix.

On our Hayabusa we have -10...

Russ,

We've used that same filter on our turbo Hayabusa for about a year, and the oil has stayed nice and clean so far.

Marty

If you accept that Laguna Seca is a handling versus a horsepower track, we were within a second a lap of most of the FA's lap times at the closing Regional earlier this year. The glaring exception...

I'm not a fan of SIR's, but if we have to do them I think NASCAR does it right.

1. There is only one manufacturer, and all plates are serialized.

2. There is a specified thickness, hole...

If the last regional at Laguna Seca is any indication, they will be closer to the FA's. With the exception of one hotshoe who was in a league all by himself (1:21's!), most of the FA's had best lap...

An interesting notion. Does the technology exist to limit flow to an absolute number regardless of pressure pushing it? You couldn't use a fixed size orifice, as it could be messed with by just...

It seems the sticking point at the moment is when you allow a newer generation motor be installed. While there are a lot of other organizations that could be affected by this theory, I'll stick with...

It was a great weekend for GonMad Racing's Stohr F1000. In a run group of 60 cars (of which we were the only FB) Don managed to out-qualify half of the FA's, all of the FE's and FM's, and all but...

In addition to our Stohr FB, we are running a car that is very loosely based on a Baby Grand, which uses a shaft drive turboed stroker Hayabusa, Atlantic tires, a midget quickchange, etc. It runs in...

As I said in posting #2 of this thread, George told us we should run 110 octane race gas in our GDRE F1000-spec GSXR; personally, I'll take his word for it!

Marty

I know exactly how you feel. Our Stohr F1000 is listed as the initial qualifying track record holder and first race winner for the Saturday race at the recent doubleheader at Sears Point. The very...

I guess it depends on your definition of pump gas. If you mean a street unleaded, absolutely not! No unleaded is legal per the SCCA defnition.

If you mean a racing gas, maybe. But don't let it...

Just wanted to comment on how nice it was to finally meet Matt and Dustin and actually see their Phoenix F1000. It is a nicely thought out package, and should do well once it is dialled in.

It...

Actually he did on that on Sunday, and very impressively I might add! That kid is a rocket!

On Saturday he was having multiple problems, so we were both top qualifier and won the race (in class)....

Thomas,

Thanks for posting the two pictures of the first lap at turn 2; by comparing them we can see that Don (silver Stohr F1000 just outside of the orange Stohr DSR at the apex in the larger...

I see the smiley, but doubt they'll be up front anyway. The Atlantics, some of the hot DSR/CSR's, and the hot FM's will be faster in qualifying. I'm guessing there will be a tight knot of F1000's...

Well that's cute; I wonder if they were going to tell us in advance that they changed our class for us? I'll have to find out if we can get a new class designation decal cut out, as we are labeled...

Matt, one correction; I'm on Don Madsen's GonMad crew, I don't have my own car (I wish!)

Marty

So you were the white car with the orange accents! Our silver car was there also. We were trying to figure out a few issues, so didn't get a chance to say hello.

One of your guys asked us what...

Maybe it started that way in Georgia, but out west there actually have been cars built or bought for FS; a car powered by a turbo Audi 4 runs regularly, along with a car that has a BMW V-12! Also...

We've already entered our Stohr F1000 at this event as a FS, as we did the previous regional at Thunderhill. We'll probably leave it this way, so we can't be protested for our new airbox!:rolleyes: ...

Now that there are a few of them running, I'm wondering what other folks have done about the cooling of their F1000. So far we have opened up the bodywork behind the radiator (per Stohr...

Well, with any luck we will have our Stohr running and debugged by the Infineon regional; by then we'll have had a couple of regionals at Thunderhill to make most of our mistakes/do most of our...
