Pulleys, Meth, And Boost Amount ?s I am still learning and would appreciate all help.
01 Camaro SS: Procharger (D1SC), SLP Long Tubes, 37.5 lbs. injectors, Blower Cam (228/228 563 114 LS), 3" exhaust, Spec Stage 3 Clutch.
1) Is there a formula to tell you what amount of boost you get from a certain setup? for example an X size crank pulley, with a Y size blower pulley on a D1SC Procharger.
2) I ordered an Alky Control meth kit for my car, and was wondering what amount of boost I could get away with on stock internals. Before anyone replies with well all cars are different and some can take more than others, I know this. I am merely trying to find the avg. amount people can get with a good tune, and safe AFR.
3) This is a throw back to question 1, and more than likely will be answered by it, but if not: how much of a change in pulley size is needed to make changes in boost. I know a .1 difference would, but I am just curious as to how much, 1 psi, 1/2, 5, etc. I would assume that it all could be determined by a formula but correct me if I am wrong.
Thanks for the help,
Travis

I would say that with meth and your cam that you could get a way with a 3.7 pulley for a good safe setup. But each car is different with mods ect.
I was getting a good 9 psi with a 3.7 stock cam + 1.85 arms. Sense then have went to a 3.4. But I like to have my boost come in much sooner on the rpm range. But I stay out of the upper limit of the band. Have also added another intercooler and custom ducting vs the stock procharger setup. So I am knocking down the pressure a bit more. To add to the picture I am at a much higher elevation 5200' so air is much harder to come by up here.
Currently working on meth as well for safety.
A lot depends on the tune, the tune can make or brake you!
