Re: Boost Question well with 10.6:1 compression and 6psi on a procharger I popped a head gasket, I then went to 9.5:1 compression and 4psi and ran fine, but with less power...

Re: Boost Question If you run racegas (104 unleaded) full time and have a good intercooler or water/alky system you "should" be ok with 8-10#s boost on a stock compression motor. Set it up a little FAT on the dyno and use fairly conservative advance.

Re: Boost Question Heres my thing, I'm buying this motor from this guy in Cali. Its an A.R.E 382 forged, and he has a Vortech blower on it pushing 6 lbs right now. On 91 he put down 681rwhp and I wanted to see if there is more room for power?

Re: Boost Question Stock compression on an LS1 F-Body is 10.1:1. If he has 10.5:1, then he had his heads milled for 4 more points. He'd better be careful with adding boost. I probably wouldn't go over 6PSI on pump gas.
