I just saw a dyno sheet of a turbocharged C5 making 597rwhp (SAE) @ 8 psi (stock block car). The car made about 520 actual rwhp. I guess the car is at a high altitude. My question is...do you guys at altitude see that kind of correction? I've never seen a dynoject make a 75rwhp or 12% correction.

 

We are at approx 1000 ft and on hot, humid, low barometric days we approach 12%, so if they are higher or hotter, etc, it is possible.
