F8L Z71 Posted October 23, 2004 Report Share Posted October 23, 2004 I don't see 400rwhp all that hard to attain on a stock system. I did 348rwhp on 5psi but I had a cam which I am wondering helped any.. I also wasn't tuned for 5psi and we had the timing set low so I could run 13psi. Jerry2500HD from LS1Tech.com did 360RWHP or so on 5psi with a basic 6.0L with no IC or methanol and just a conservative tune since he uses his truck for towing. My guess is that the SS truck could get damn close to 400rwhp on 5psi if you tuned it to run exclusively at that amount of boost. Obviously until it is done it's all heresay but still it doesn't seem inconceivable. Link to comment Share on other sites More sharing options...

It doesn't have to be 436 @ 5 psi Link to comment Share on other sites More sharing options...
F8L Z71 Posted October 23, 2004 Report Share Posted October 23, 2004 True that I just wish we knew how to tune for methanol back then because I really feel that dumping too much meth is what killed my top end HP... I mean IMO my graph looks funny. Through the whole pull I only gained 36rwhp. I had over 400rwhp from 4200-6700rpm. LOL Link to comment Share on other sites More sharing options...
