Back in the fifties, an empirical equation for quarter mile speed was developed by George Wallace, of the Vehicle Performance Laboratory at Chrysler. This was used by the Ramchargers and others within Chrysler. It was [225(HP/#)^0.318]. This is not as convenient as the equation given, since many calculators have a cube root key and the 0.318 power might require some extra keystrokes. It is, however, a more accurate "fit" to the data. If you exclude aerodynamic effects, the cube root is actually to be expected, so the deviation from the cube root could be considered an aerodynamic "fudge."
The horsepower is at the flywheel.
