Hey guys im trying to figure out if I need to get a smaller pulley before I dyno or not. Ideally id like to run 10 psi or higher. Last time it was a v1 w a 3.6 pulley on a 97 Cobra motor. This year it has c heads, LTs, IC, and a anderson power pipe. Essentially its a bolt on Mach 1. Running the same blower and pulley. What do you think, should I go to a 3.42 or even a 3.33
