Horsepower Calculation?
I've searched everywhere for an equation to figure front wheel horsepower and found nothing. I've found a TON of rear wheel calculators. Does anyone know the equation to figure a vehicles HP based on ET, trap speeds, etc? I will make my own frickin' calculator.
Any ideas on where to look for the equation?

I'm sure its pretty much the same as rwd cars except our loss of power through the drivetrain is about 5-10% less. Try http://www.smokemup.com/utilities/calc/hp_et.cfm

So does anyone know the actual equation to calculate the HP from the ET or MPH?

This are pretty rough, but how about: HP = ((MPH/235) ^ 3 ) * Weight (lbs) This from HP = 550 ft*lb/s, 1/4 mi distance, no tire slippage or air resistance. The cube comes from deriving acceleration -> distance. |

The MPH in the equation should be your speed at the end of the 1/4 mile (is this what's called the "trap speed"?). I agree, 431 hp would be pretty nice for an accord, but so would a 1/4 mi @ 117 mph. I think doing a HP calculation based on max speed would require knowing the car's frontal area, altitude, etc. |
