DOES ANYONE KNOW OF A FORMULA TO FIGURE HORSEPOWER GENERATED TO PUSH A CAR WITH A KNOWN WEIGHT THRU A QUARTER MILE AT A GIVEN SPEED OR ELAPSED TIME?

THANKS

I remember seeing a website with it once, but I forget it, maybe someone knows what I'm talking about.

MPH = (cubic root of (hp/weight)) x 235

ET = (cubic root of (weight/hp)) x 5.835

This numbers only represent perfectly flat power curves and no time lost to gear shifting and tire slippage. In others words a perfect mathmatically possible run....add about .5 to 1.0 seconds for real life times, however the mph should be close enough with the result being about 1 or 2 mph faster than real life.......

By the way, I got these formulas from out of a past isue of hot rod magazine
