Well i decided to supercharge my 94 z28, but mean while wanting to keep it low in cost to install on my engine, they say it'll push up to 400hp with an aftercooler. I just need some info on what i need to do to the engine, I was told stock short blocks will hold the power but unsure of that being just a rumor. I installed a new oil pump and gaskets all ready do too high mileage on the car,,....... the trans was built to hold over 800hp, with all steel mirco polishes race components and modified shift kit with no shift ***** and a massive valve body its a 4L80E Specs, Aluminum drive shaft and mild build on the rear diff. I just asking mainly about components needed for the engine I'm gettin the full vortech kit with aftercooler.

 

if you stay around 6psi i think all you need is a tune

 

Yeah, I actually heard you really need that tune before you even run the car, otherwise your AFR and whatnot will be off and can hurt the engine.

 

My buddie owns a 94 Z28 hardtop 6spd with 4.11 12bolt posi and Z06 race clutch and forged bottom end in the engine with a .305 cam and 58mm trottle body is running his around at 14psi with no tune just bigger injectors

 

with that kind of a build i find that hard to believe. i think your bud is givin u a line of bull or hes wasting alot of hp and gas.

 

yes you NEED TUNNING after the install, baby the hell out of the car when your driving it to a shop when your done with that
