Spitfire S,
My race car is running on 15" slicks with a diameter of 565mm.
It weighs in at 560kg plus driver.
Engine is stock JDM with almost open custom headers. With pump fuel it would top out at 8600 on our fastest local track. With Elf race fuel it surprisingly bangs the limiter 100m before the end of the straight. The factory ECU rev limiter has a few 100rpm hysteresis so its the last thing you want to hit if someone is slipstreaming behind you. The engine full cuts until the rpm drops a few hundred rpm before the power comes back on.
I have another F24C engine which hits Vmax even earlier due to the lower rpm limit and higher power.
