Sorry- thought I replied earlier- yes, I've got the new engine. Currently selling it-

My car is back together ready to race or sell! I've got it up on the Facebook Stohr cars group.

It's the car below- the link in my previous post goes to some video (including drone footage) and still shots of it. It's BRD bodywork and HRP wings (not all the photos have the updated aero package...

I was driving the Red/White F1000 Stohr- after a year of development it is the most amazing car I have ever experienced. We just added the brand new HRP wing package and it made a night and day...

The secondary injectors are phased in somewhere around that RPM. Check wiring to the upper injectors, also switch upper and lower injectors to see if you can move the problem. If the car has sat...

I'd like to offer a little perspective to some of the previous discussions and proposals, specifically comparing FM to FB and allowing modifications to speed up FM.

I am in the unique position to...

What Steve said is correct but to put another way:

-They all spew fuel out of the air filter. There is a resonance at the higher RPMs that bounces the air/fuel mixture off the walls of the air...

Challenge accepted....

Yes- it is Treys car- with a lot of changes and updates.... we started with a good base and improved it-

-Fresh FM spec engine
-Frame-up rebuild
-Rebuilt transmission
-Rebuilt shocks
-Similar...

Wait- are we talking about the same thing??? :o :D

Well, we are a full service race prep shop...

Well, we've found a way to make the cars even more sexy....

This is our newly-rebuilt rental car-- we are very happy with how it turned out and how quick it is...

Pictures are from the...

VIPER is now renting cars as well- we have a really good Mazda program going and are coming off of winning both Road Atlanta Majors races with Robert Noell. Please give me a call at 919-349-7510 and...

First off let me start by saying that I (and I think everyone in SCCA) really appreciate the hard work done by the folks in white without which we would not be able to race. This goes without saying....

The Majors double at Road Atlanta turned out to be a fantastic race- the weather was great (no rain, warm and sunny for the most part)- and there were some very fast Formula Mazda cars there.

The...

Not to speak for him but... Alastair McEwan is planning on being there with the Phoenix...Umbrella girls are probably a given.

You should be fine with the standard cell. We had a custom ATL cell made with about 12 gallons capacity (was intended to be identical to a standard FM cell but came out wrong) and have no issues...

Thanks!

I was learning the car throughout the day- I only have a couple of laps in it several years ago. As it was a borrowed car I was very conservative-- the primary goal was to bring the car...

I had the opportunity to compete in the VIR Ultimate Track Car Challenge over the weekend and had a blast! I'd like to thank first and foremost Bob Wheless for loaning me his Stohr CSR for the event...

And we've done our homework on the aero...

Full scale testing at Langley wind tunnel.

It can be compared to a ABS system as under any conditions there still is downforce. The system simply adjusts the amount of downforce.

I'm guessing 20 years ago there were similar discussions...

Active aero is an interesting topic. Funny how the ghosts of failures 30+ years ago are still around. Just like any component it can fail but I'd say it's safe to say that we understand a lot more...

My mistake, link should be fixed.

We often use the Traqmate system for basic driver analysis and comparision. They are inexpensive, reliable and easy to use. We have a Traqmate Basic system that we will loan to people that can...

To be clear- this car was running as an FS with a streetport 13B. We work with Old Dominion University and the motorsports program; one student used our car as a senior design project. The result:...

Here is a shot of my Formula Mazda in the Langley full scale wind tunnel.... It is now an FS car with a streetport, MoTEC fuel injection, E85 capable and occasionally active aero car.

Tom-

Our streetport in FS is making around 200 (230 at the crank) at the wheels but torque is significantly less than the standard FM engine. Our gearbox wear has dropped significantly compared...

Come up to the March Memories at VIR in Early March- I'd be more than happy to sit down with you and go over the data system, car set up etc-- there are a lot of straightforward bits of info that I...

This is my interpretation of the fuel rules and a little history.

Ethanol is added in varying amounts to pump gas. It depends on the area of the country and time of year how much ethanol may be in...

Coop-

Sorry, should have said 'Some' of the folks at the ARRC were using the fuels. I thought I smelled more than one--

And I'm not implying that anything illegal is going on- quite the...

Not to disagree with the folks at VP but... we've tested some of these fuels for dielectric constant and they DO NOT pass. Some are well over the allowed DC. They make power however! I expect the...
