My IA runs closer to the uncorrected numbers(132.5mph 3595 lbs) which is less than the 695 corrected. probably because most track days are warm and humid like the dyno day was! The 455 in my TA at 3750 ran 124 mph and only dynoed 525 corrected! Wallace calculator and Moroso slide 550 hp.Different dynos.
No doubt you need to know your exact race weight at the very least when trying to convert et/ mph to hp

Body style and wind conditions will play large factors as well….a low slung car with low frontal area and a tail wind will obviously mph higher …

Not an exact science by any stretch!
