Hey Guys,

I have not hade a chance to get to a dyno yet-not to many out here is South Dakota, and i was just wondering what kind of rwhp #'s i might expect to see.
Also i am not sure at what rpm i should be shifting at. Tough things to answer without a dyno. Give me your best guess-here is what i have-

2004 Chevy rcsb 2wd with 265/50r20, 6.0 iron block, stock crank, 8.5 to 1 low compression diamond pistons, stock alum heads(317)with ls6 valve spring-rest of heads are stock, stock intake, 8.1 truck injectors 31lb, stock exhaust manifolds, Lingenfelter GT2-3 cam. FLT 4L65 Level 5 Tranny, 3.42 gears in stock rear end and a Whipple Supercharger running 10-12 psi using whipples computer with efi live programming-running rich right now 10.5 a/f-but the whipple computer is coming off. 05 E-fans, Innovators West Billet Aluminum 10% overdrive crank pulley and a dual in dual out Flowmaster muffler. i am at 3200 ft in elevation if it matters.

thanks

 

~425? Just a guess for you. I don't think you have enough injector or pump (assuming stock?) to support your fueling needs @ 10psi boost but I am far from expert.
