Horsepower Estimate?

But it's best average hp to the ground to get best e.t., not peak, and those formulas only spit out peak.

All drag strip show who's using their available power more effectively, if we got similar cars and I make 10% more average hp but your faster your being more effective with your available power but I would have more overall potential.

All a dyno shows is potential, that's literally what Rated Horsepower is work potential.
what it spits out is the best possible et you can run period
avg power has zilch to do with it
