For those of you that race SCCA you may well know that the E36 BMWs are perceived to be overdogs in the ITS class. Recently, the SCCA comp board ruled that the BMWs would be required to run a 56mm restrictor plate.
I don't know if this is a problem or not. I mean, Ford used 55mm (and smaller) mass air flow sensors on 5.0L Mustangs back in the day and some of these would make 250 hp to the wheels with stock bits.
So, those SAE types on the board, got any quick calculations that will show how much hp this can suppport? Of course, this will be RPM dependant I think, so, max at various RPMs might be the question with a 2.5L motor (inline 6).
Doesn't NASCAR use some small restrictors but still produce some serious hp?
Thanks,
Ron
