Today in autozone this guy with a 93 ssei said my friends 99 grand prix gtp could get 350 hp from a intercooler a cold air induction kit and a smaller pulley for the supercharger is that legit?

Wouldnt that be adding around 70hp to the vehicle?

I dunno he said from 330 to 350 hp with that

KILLER!

Listen to me. You're making a fool of yourself. Have your friend that OWNS the GP join either here or ClubGP. Don't listen to people at Autozone. Don't listen to claims on Ebay. Get the real poop from the people that do it every day.

Yeah that'd be close, but you could do a lot more before the intercooler. Rogue'* got over 400lb/ft and he'* still IC less.

WOW-if thats true I wouldve been around 600hp

321FWHP. with pretty much EVERY go fast mod except an I/C. The car couldve prolly been dynoed closer to 380 with some EXTENSIVE tuning (No timing, and 8* of KR).

YEAH! Don't listen to folks at Auto Zone! Or NAPA! Or Advance! They're the competition.... LOL. Come in MY store! retail stores

IC'd with a 3.0 pulley, PCM and exhaust work might get him in the 300 range (crank). 330 would be pushing it. Engine may not last to long though reving that high without internal shoring. Try reading or searching clubgp.com for a bit.

may i ask why NAPA?????

Most NAPA'* don't have a Manager who owns a modded Bonnie Nothing personal against you Kenn.
