3.2 makes 7psi and i what 9psi would a 3.1 or a 3.0 be best on a p1 6 rib setup

Depending on your exhaust,etc.. a 3.0 should get you close to 9.0psi

You will more than likely have belt slippage problems going any smaller than a 3.2 on the pulley. You would be better off finding a larger crank pulley. ASP makes them but they are not cheap. Bob
