I have a 91 Z28 with the 5.7 and around 35,000 orignal miles, I am looking into installing an ATI Procharger P-1sc. Here's all the mods I have currently, Edelborock High Flow Intake and Runners, Edelbrock/BBK 52mm Throttle body, Hypertech chip, 3" Flowmaster American Thunder Exhaust (with High-flow cats), Richmond 3.73 gears, 17" 275 Zo6 wheels on Firehawk tires, and an SLP Shift Kit.

I dont want to wear on the car to much, and as u can tell by the mileage its not driven much. I was thinking of going with the 12psi set up, and was wondering if u think this will be pretty safe for my car and how much horse do u think I will be making? Thanks guys

Sorry bro, guess im just a little anxious and wanted to get as many opinions as possible.

i think 9lbs. would be about as much as i'd go on a stock motor, (i use to deal in 3rd gens, and my son has a 91ta, his friend a 89gta, and my bro in law has a 91z)
