Post your BONE STOCK LS3 dyno numbers...
Please list: mileage, transmission, octane, if NPP or z51, type of dyno, A/F ratio if possible.

The lowest so far 366 while the highest is 392!!! I realize the NPP may add a few horses. I know there's a lot of factors involved, but 28rwhp is a big variance!!!

SAE net horsepower is still power at the flywheel. Contrary to popular misconception it does nothing for rear wheel horsepower. It will not, does not, compensate for individual dyno operators, Environmental conditions, nor for the wildly mistaken beliefs regarding the parasitic loss of the drivetrain.
Rear wheel dyno numbers are good for the exact car at the exact time in the exact location under the exact conditions and are virtually useless for comparing one to another amidst a sea of variables that exist between the two. Even then it is virtually useless to measure gain unless you know what the flywheel horsepower of the car was. You still have no idea what your individual parasitic loss was through the driveline.

What I'm talking about is comparing different cars on different equipment on different days under different conditions by different operators. The only controlled variable you have is they will be different.
While most dyno software possess the ability to apply SAE correction, if the operator does not input the variables data correctly for temperature, humidity and absolute barometric pressure at the time of the test, then yes I'm saying the owner is walking away with a misguided sense of his actual horsepower or worthless numbers on a page. They will always have however as Modshack demonstrated, a pretty picture to present to the forum or for bench racing with their buddies.
It is also worth mentioning that to acurately apply SAE correction there are maximums that can be adjusted for variables, what are the odd that a particular operator on a particular day will know and apply this mandate?

Which SAE format are you discussing? Are you talking about SAE net power or J1349 correction forumula or similar?

1340 miles, Z51 MN6 with NPP, 93 octane - 390.5 hp.
I can't find my dyno sheet right now, but it's the dyno at MTI in Houston. If nobody else posts what their's is, I'll look it up later. Gotta go to the in-laws now for turkey!
