558 rwhp Turbocharged GMC Sierra Dyno Run
Made 558hp/507tq on this run. In this vid, the truck has a 5.3L stock bottom end, Custom Cam by Geoff at EPS, Comp Dual springs, very lightly ported heads,Trick Performance front mount 70mm turbo kit, FAST 65lb Injectors, 3" downpipe, Snow Performance Stage 1 Meth Injection Kit, and open Exhaust after the DP. Dyno and tuning were done by Geoff Skinner at Engine Power Systems - Baton Rouge, La.
It should be making more toward 600 to the ground, but my fuel pump is dropping way off at the end of the run and cant keep up. AFR was almost 13 on this run, so its very lean. Next mod will be some type of Booster pump set up.

The 5.3 got a little upset one day and melted the top of a piston....So, we found a 6.0 Litre and put all the goodies in it from the 5.3 and opened up the top ring gaps to 30 thou. Should be better now. Josh had it all up and running again in a week! Has more jam at bottom end than the 5.3 he reports.
