Figure out your horsepower without a dyno!

Easy way to figure out your horsepower. All you have to do is know the weight of the car and the ET, and Trap speed. Have Fun!

This is flywheel horsepower and reads higher than what your wheel horse is but it will get you close.

Just playing arround I did, 8.75 @ 166 (AMS's video'ed run) with 3500LBS (I would think AMS's Evo is lighter, but I guessed) and it came up with 1141.06HP. I wonder how close that really is?

Those calculators are not accurate. You need tire diamteter, gear ratio, DC, frontal area, and some other junk.
