I’m sure this will be opening up a can of worms...... but.....

If the dyno is sitting at 5200’ elevation.....the observed barometric pressure at the dyno shop was not 30”........ it would have been more like 24.50-25.00”....... which is a pretty huge difference.

30” could have been the “corrected” barometric pressure........ which is what the pressure would be if you were at sea level.
But that’s not a number that's used for any of the normal SAE corrections.

“Uncorrected” tq/hp is just that........ raw data.
If the motor made over 500hp, without any correction applied, while being tested at 5200’ elevation in 91* air....... there is going to be a pretty huge correction factor to get back to “std corrected data”(29.92”, 60*, zero humidity).

That being said........ if the math showed the corrected numbers to be 670hp......... I think we all know those numbers wouldn’t be duplicated with the motor tested at a legit facility much closer to actual sea level.
