I'm looking for baseline Dyno results for stock '10-'13 GS's, Dry-sump LS3 only, preferably with NPP exhaust, no other mods.

Edit: Only looking for posts from people with dry-sump LS3's.

I'm gonna guess that this is a subject that's been beaten to death and the answer is just about the same as any other LS3?

The problem you have is dyno's have a specified accuracy. The Dynojet's accuracy is +/- 1% . That means on a 400 HP reading the true HP could be anywhere from 396 to 404 HP. To get a feel for HP differences in that range you would have to make 10 dyno pulls and average the readings for each engine you wanted to test. Anything less than that and you might as well not bother.

It's a LS3. NPP gives it 6hp. Dry sump don't do crap. It will dyno like every LS3, and like Dearborn said.....do about 10 and get an average.....and he would know.
I like your color, tho.

Not sure if it helps or not, but should give you a pretty good idea. My 08' LS3 baseline dyno wast 378 with Fusions and no other mods prior to its build.

Mine made 378rwhp

It's SAE certified from the factory.

And will dyno like any other factory LS3 w/ the NPP, dry sump or not.
