double key crank and billet crank Hub...so much more to go over...man!..even on a P1SC street level procharger they will spin the impeller up around 40,000 rpm..the f race series will go 60,000 +

so much you need to do here..maybe a cam change "wider lobe seperation", o-ringed head or minimum of cometic head gaskets depeneding on yout set up. properly set up blow thru carb or i would stronly suggest electronic fuel injection..
