: Safe amount of boos for stock motor?

I'm wondering what's generally considered a relatively safe amount of boost for a stock N*... Reason being is I can get my hands on a very well priced Procharger P-1SC.. It was originally designed for a kit for a 4.6l mustang GT, so it should work just fine in the northstar fiero..

The only things that are done to the motor is port/polish heads, new head gaskets, timeserts, head studs and possibly a valve job and cams...

Would it be safe to run 7-8psi on a stock motor, and expect 450-500 rwhp (through a std trans)?

How do you plan to hack the computer?

The general consensus is 7-8psi with an intercooler is fine on a stock motor.

what ecu are you using with the northstar now, and what did you use to tune the ecu to work with the northstar.

It's a re-programmed GM 7730 ecm using $8F code and a custom wiring harness.. I don't know all the specifics on the ecm, since I had another guy do it for me, but I did make the custom wiring harness for the car.

Unlike in the caddy, where the ECM has a connection to pretty much every single little detail in the car, the 7730 is using only the bare minimum sensors and outputs to run the motor, and that's it...

thats all you need when all you want is speed :) I may be asking you a few questions if I start on my Northstar Hot-rod idea in the next couple years (I hope to anyway).
