how much boost??? D1SC to F1R
is the d1sc made 15lbs how much should the f1r make?
Motor is a sbf 331. ported canfields. blowthrough carb.
Ok at 6800-6900rpms the d1sc made 15lbs of boost with a 7.65 crank pulley and a 3.70 blower pulley12 rib. So now I'm putting on an f1r. I have a 77 tooth cog crank pulley and two blower pullies. A 54 tooth and a 44 tooth. Is there a way to tell what kinda boost the f1r is gonna make going from what the d1sc made?
