Quicksilverado Posted March 7, 2007 Report Share Posted March 7, 2007 Its all in the tune. My stock 5.3 put 500 rwhp down at 8 psi and no I/C. You will need a new fuel pump and 43 lb injectors. At the same boost levels the sts will out perform a maggie. The s/c will have alot more tq off the line where the turbo will have lag. You can setup the turbo to have very little lag however.

Same deal here...my stock LM7 with 8# of boost put around 460rwhp with 43lbs injectors and a FMIC. Reason my numbers were a little lower was I had a GT76 which is a little too big for the LM7 to spool up too quick. I'm installing a Forged LQ9 with the GT76 and should see 650+ rwhp. However I'm sure I coulda run 10# safely on the LM7. I'd say go for it and you'll be happy you did. Quote Link to comment Share on other sites More sharing options...
trtturbo Posted April 22, 2007 Report Share Posted April 22, 2007 guys, we typically sell more STS kits than anyone in the nation. We have changed a few things and made additions and the kits can work very well. A large majority of the issues are due to the installer. For anyone that thinks they dont perform, we have a SSS running 7.30s 1/8 mile and soon to be in the 6's. It does have a big motor, but we are only running 10psi. We also are doing this through one of our 4L60s. We are shooting for the fastest SS in the country. Quote Link to comment Share on other sites More sharing options...
