After all, with my body work QC, how I can assume the engine was put together correctly too lol.
This was done today, about 75 degrees, not too humid, 93 octane, 1400 miles on the car. The Dyno is a Dynojet. Runs were in 4th gear, 1:1.
We did three pulls, each pull the whp went up a bit. I think a couple of more pulls we would have seen maybe 3-5whp more but I was satisfied .
I'd say the 472 SAE HP is dead on assuming 12% loss and the 445tq is a bit underrated.
