I;m in the market for a SC and i was wondering what the best amount of psi would be to run without blowing tranny and rear like some other guys....98 camaro ss...thanx Greg

 

on a stock LS1 i would not go with more than 6#'s w/IC. ATI's 4# kit will take a stock 320hp LS1 to 440hp. the 7# kit gives 505hp. i think you could gp with the 4-5# kit and be ok with the stock rearend if you don't run really sticky tires so your tires break loose before the gears. the 4# kit is a complete kit. stock injectors and computer programing. give SPEEDINC a call and ask for larry. tell him randy (black ss ATI s/c) sent ya.

hope this helps
