i can't wait to hit the dyno

how would you calculate crank HP without pulling the engine? I know crank HP is basicly a useless value because it doesn’t represent usable power but how would you do it. I have always herd 15% for MTX and 20% on ATX is that way off?

well, that’s exactly the point. and since most modded cars are compared by WHP, why generate a FWHP number?
