Ok I ran on the Dyno tonight and got three pulls of 391, 388, AND 396 H.P. Torque numbers about 10-15 digits lower. The grapgh says SAE Corrected numbers. What does this mean? The guy at the Dyno shop said to take these numbers and divide by 18-20% to get crank numbers. Is this correct? If so 20% is putting me at 495 H.P. at the crank with only Bassani Exhaust. Any info would be appreciated. I think it sis my Trim lok on the vent cutouts thats doing it for me, even though the hood was wide open.
