My math says Mazda 2, Mathis, Brannon . Edit. Totally forgot Sargis. Sorry . I think that the Mazda is still 100# less than the very similar Toyota that ruled the class.? Good luck to all. Heat the tires up before the kink. Safe racing .

Why dont you simply ask for Ep allowed to use 8 wide. ? Why complicate things ? Also I dont recall seeing your name on any grid sheets? Do you race ?

All I see is anold Smile chart . No link to donate. Please post your email oor a link to PP clicker. Thanks.MM

Youre my new hero . SCCA attitude at its finest. Thanks . Your statement reminds me of the tech guy that said that I could not get a logbook for my Chumper truck because its the" Sports Car Club Of America". Hostage levelWTF . If any tire rule is updated. We should maybe adjust to the era...

FWIW our car has gone fastest and run 8 sessions on R7 , not the slicks. Even when we won tires, we replaced them with more R7 . harder , wider. My data testing VS slicks showed the same lateral and almost no loss in roll speed. Will tolerate more pressure when needed ,etc. For SCCA...

I took the survey. I believe that we need to keep the LBC cars at 1500# on 6 in rims. Increasing their corner speed even higher than it is now will make for lower lap times for them, and increase the delta to the 2100# cars mid turn. The opposite of what we really need . Somehow, adding...

Might check alternator bearings and/ or under drive it .

What would be a more standardized method?

https://classicfuelinjection.co.uk/su Just like this only mo better.

The injector will simply spray the fuel at a metered amount, exactly like the carb jet. The resulting spray will be distributed along with incoming air flow . There will not be a huge difference from the carb's jet spray . Simply better regulated . Air and fuel make power. IMHO the...

What about today?

What about now? Can FP and GTL can find a box stock engine package?

Where is the definition of throttle body injection? If they are not in the intake or head, they must be TB injection. Maybe the trumpets would have to be welded to the carb to be one piece. Kinda like the old days with epoxying the wheel spacers to the wheels.

In my Turbo jetta chumpcar ( Roadtster, cuz light weight helps things last ) . I doubled the torque over the carb NA version and only picked up 3 mph . I looked into aero auto and came across a bunch of hypermile stuff. They did a lot of coast down aero drag testing. I had access to my...

Remove throttle shafts . Attach throttle cable to the top of the piston, like a bike carb . Fit the inlet trumpet with injectors. You will need an RPM signal, map sensor, maybe TPS, Wide band system, one of the many stand alone ECU. There may be an optimal spray direction for the...

Is anyone working on this yet? I can help engineer it /tune it . All I see is a naked carb body with the piston as the throttle slide( no shaft or plate) and an injector spraying into the venturi . That still fits the rule as its written at this point .

Ive changed a few to Microsquirt . Cheaper and way sturdier. You may have to change the wheel and trigger also. I use a Nissan VR trigger on a Ford 36/1 wheel .

I agree . Sebring or watkins glen would have better balance.

Thank you. I had a soft cylinder and failed to discover it until we got there.

Look up the LR and results for recent races.
