I have the following Procharger P1X pulleys and what they made in PSI on my car. Only change since then is that I went from high flow cats to zero cats.
4.75 = 7.75PSI
4.25= 10.63 PSI
3.5=21.3 PSI (E85 only pulley)
I want to find a good 93 pulley for my setup I currently have the 4.25 on. I am also on a built 9.5:1 CR motor. Iām only making 618WHP and 493WTQ on this 4.25
Iām thinking of going down to a 4.0. How much PSI would that be ? Or 3.9? 3.8?
