Inlet @ .500" lift = 304cfm Inlet @ .600" lift = 310cfm 310cfm = ~450hp To get our planned 500hp, we need 340cfm @ .600" lift ... so the porting tools are now out !!!! Focus needs to be on both inlet and exhaust porting to get to where we need to be. For anyone looking at NA VQ engines, there is no way you can flow enough air to support more than 440-450hp at the crank ......... regardless of inlet manifold - the heads simply will not support more flow than that. badthing, hooey_b and 260DET#1 like this.
