Question about 1998 Z28's HP level

ryanz400 · 10-30-2005, 03:20 PM

Hey guys. So far I have hypertech programmer, Flowmaster Cat Back, MTI intake, Ported MAF, and 4.10's as far as performance. 315 rear tires, bmr control arms, and everything else is for looks or stereo. I was wondering what the HP limit is on these ls1's in 98. How much can the rear end's take? I'm thinking of a Vortech Charger w/aftercooler to put me around 500. I bought a Nitrous Express kit and was told the 200 shot would be just enough. I heard 550-600 was the limit on everything without stuff starting to brake. Thanks

depends on how you drive..... i have 400rwhp and a 4:10 10 bolt and have had no problems..... but im easy on it.....
