I messed with a few calculators. There is for sure more to be had. I will get the car weighed and start off right away with a log book to keep track of everything, tune, air, car changes etc.
I am wondering how the 4:30's will work... I don't have an 8" converter.... Lenny built me a 9.5" unit... It flashes around 4200 rpm off the bottle... I never tried the NOS out of the gate, Lenny was telling me it should go 4800-5000 on the bottle. He was dead on with off the bottle flash so I'm assuming he will be correct with the Bottle Rpm flash.
