I have a 94 GT 5-spd w/373 gears, flowmaster 2 chambers,and a mac h-pipe. I want to add some power, what kind of supercharger and shorty headers would you run. How much boost is safe on a stock motor? What HP and performance can I expect to see with these items?
I'll be but I really just want to break 330 for now. If I can do that w/ out any type of power pipe w/ that reducer in there then I'll know I can unlock alot more HP and PSI once I get that out.

I mean stock being heads and bottom.
I was going to go w/ a Procharger but while I was saving up my money for one I read a thread in the 4.6 section from some guy who just put a P1SC on his and 500 miles later the head unit was leaking. From what I hear procharger had fixed the problems of there leaky head units. Some people never had any probs and some people had constant problems. I think alot of it was due to people over filling the head units although they swear up and down they dident
