So what causes the difference in horsepower ratings between ET & MPH formulas ? Which one is accurate or do you average the two?

John,you know I've gotten blasted by some here as making excuses when I mention "conservative dyno numbers" that match the Moroso slide.

Here's the 525hp engine dynoed 455 in a 3750 lb TA with a street convertor
60 ft 1.616
1/8 7.04 @ 99.1
1/4 10.995 @ 124.5

old goat racer, the MPH equation is probably more accurate.
ET can be affected by many things.
But the MPH is usually the same if it's ran all the way through.

For an excellent ET calculator, try ET Analyst

It uses more inputs and is relativily cheap.
