i have a 90 iroc that i put 350 in last year with the b&m ripper shifter. this year i got it supercharged by procharger and installed 3.73 gears in the rear. its been tuned and dynoed at 392 hp. it's fast but i need more. any suggestions.

more than 392?

smaller puller, intercooler, new internals, nitrous oxide injection..

there are all kinds of things you could do.

Forged internals. Maybe a stroker kit. More cubes are always good. Dished pistons, lower comp. ratio and more boost.

Or you could go with supporting bolt-ons if you don't already have those. Longtube headers, true-duals, cutouts, suspension and chassis, heads and a blower cam.

More displacement, twin turbos & intercoolers

yeah u need forged internals and alot more boost!!!! and the bolt ons that were mentioned if u dont already have them

i was told that if i got more boost that i would have to change my injectors and that it may cause problems down the road. would there be more to change and would it cause problems later

wth??? why would it cause problems? im about to throw sum 42 pound injsectors (if i remember correctly) in my car...new set up will be 2 stage n2o...75 dry shot off the line, followed by a 150 wet shot at a pre set rpm working off a window switch... right now im doing a 100 shot and the injectors cant keep up, so im gonna have to go big..so will u if u up the boost..only thing that will mess up is your wallet when it comes to gas lmao! as long as u tune the car correctly after u have done an aplication like that and balance everything correctly for your setup then u will be just fine man!

Get a 454. If you want bigger numbers get a bigger motor. If its a street car than the HP you have is plenty for a car as light as yours. And how the hell does it only have 392 HP with a S/C? You can get a 350cid to push 375 HP with all stock parts...

i was looking into getting a new intake, runners and base then maybe new heads for the bolt ons. how much more power do you think i would get
