After doing a little research, I guess I'm still not understanding what's happening hear. I looked up a few dyno results on the Camaro forums and found this. (All were stock)
Camoro SS Auto (L99) rated a 400hp, most ranged from 300 to 330 rwhp. Depending on location tempature etc.

R/T auto & 6 speed (Not much difference in results) rated at 372 hp ranged from 330 to 340 rwhp.

From what I've read one should average about 15% loss from the crank to the wheels. If so there is not 15% with the R/T's. Are the engines under rated, or are they not having that much loss in the drive train? :think:

i would lean towards underrated #s but then i have read that some guys said they only had 290 at the wheels with their RTs.:think:

While I'm not a mechanic or can say I fully understand HP ratings or dyno testing etc I do know this...
If there is not a measurable, objective standard, that can be applied in all circumstances regardless of variable factors...weather, temperature, humidity etc then whatever numbers are derived, while not worthless per se, are not really valuable.

Example...take two stock cars right of the assembly line.
Dyno test one of them in Alaska in winter and one in South Florida in winter.
If the results are the same fine...you have an objective finding. If they are different then which vehicle has the true HP?
Answer...both...for their location.

I don't know, maybe I'm just talking out of my rear. But I do need to get a set of cat handcuffs today. Stupid cat.

Yea I can see that Alaska / Florida difference. But out of all that results I looked at (got em printed out), I'd say the average of the SS L99 is 328 rwhp. The average on the R/T is 335 rwhp. We're talking 400 vs 372 rated hp. But when dynoed (on average) the R/T is stronger.
Hey I like it. Maybe I'll get to run one at the track one day to see.
