tough question to answer but first of all make SURE you have a good boost gauge that reads acurate boost, you can run 9 or 10 PSI's and SHOULD be safe, ofcourse I don't know your car, how many miles and how good it runs.
you be the judge
i bought a faze gauge. I dont know if its good or not havent hooked it up yet. And its an 84 ae with like 66k miles on it. runs great. Also people have told me to get a stage 2 clutch on it cuz i need a new one and i was wondering how much will i that help the car?
stupid question #25 on my list of stupid frequently asked questions.
How much boost can I run?
Eleventy billion. Seriously. Depends on (but not limited to):
engine condition - includes:
octane fuel used
temperature (air and engine)
Ive been running an ACT clutch for 1 year now with no problems. The most power I was able to get out of the stock clutch was 290rwhp and then it started slipping on the dyno, although the dyno puts more strain on the clutch rather than if you were on the street.
Most high-perfonace race teams use Spec clutches. I walked into a place here in Central Fla. where they do nothing but build high-perf. Porches, Nissans, Toyotas, and one other manufacturer, and they said that they have tried almost every clutch out there, and Spec was the best. My bro has a 6-puck sprung clutch from Spec on his 413 rwhp SR powered 240sx, no problems what so ever.
so over all buy a act centerforce clutch, a boost controler( not a cheep one), and a new better boost gauge, then you can run what every you feel like running in your car as long as you know what will happen.
