If you run them at the same AFR GM runs them at, they're actually right around 426 with the GM manifolds/cats/full exhaust and the full intake and full accessory drive with load on it...good luck finding an engine dyno where you can run the entire Camaro exhaust system though.

I don't doubt that it's making 488 hp on an engine dyno...think about it, take a completely stock LS3, with every single component from the car on it, and run it really rich like GM does stock...now pull the accessory drive off lean the car out to ~12.5:1, probably add a degree of 2 of timing, and change the air intake...488 isn't far off at all.

They said baselined at 420hp before manifold
When they come back from Sema they will put my car to stock dyno it then dyno it with the manifold alone, then put my parts all back on and final dyno 
So cant wait, Ill get back to you guys with numbers and the feeling when its all done!!! |
The only way for it to be a really truly valid test, is not to return the car 100% to stock...because they're not going to tune it the same as stock with a new intake manifold on it. The only correct way, is return all mechanical parts to stock, then tune it for max performance...perfect the AFR and timing...there is power left on the table in the stock tune and everyone knows this. Now change the intake, manifold only, and re-tune for max performance again...if it tolerates different timing and likes different AFR, that's fine, it can be directly attributed to the intake manifold, and the tune changes are necessary...but since the stock tune is not optimal for max power, comparing a 100% stock car, to a car with a different manifold and tune, is not apples to apples.
