Old Drag Racer Formulas: The "Q" Ratio or Factor??

ET/MPH From Horsepower Calculators

Used this when I was racing a long time ago, accurate for my cars and others I have tried and know about, will show numbers for a reasonably good leaving car, mph can be slightly over by 1mph. Won't work well for any S/SS type leaving car. You can also work out your fwhp from your weight by changing the hp numbers till you get the same as your slip mph. The Moroso wheel will show less hp.
