Horsepower Calculator
I found this neat little horsepower calculator. Not sure how accurate it is but it determines both at the wheel and at the flywheel horsepower as a funtion of vehicle weight and quarter mile time. Here's the link if anyone wants to give it a shot. I would be interested to know how accurate it is.

Re: Horsepower Calculator (Torqued84)
It seems fairly accurate. I put in weight (for car & driver) as 3400 lbs and 11.71 seconds through the 1/4. It calculated 418.5 hp at the wheels. Last dyno run netted 414 rwhp. Pretty close. However, I don't know the exact weight for car and driver- just a guess.

Re: Horsepower Calculator (Dr. Doom)
I think it's off! It says that I have 380HP at the flywheel - my car runs a 13.2.......I'm pretty sure that's wrong! Last time I weighed it, it was 3406 with me in it.

Horsepower Results - 1/4 Mile Method
Your 1987 Corvette weighs about 3500 pounds and can complete a 1/4 mile in about 14.0 seconds. That means that you've got about 252.10 HP at the wheels, and about 327.73 HP at the flywheel.
Who said that the airfoil doesnt work? :smash:

I like the ones that use MPH much better, this is way off...

Re: (scorp508)
Try this one, http://gafba.com/calculators/hp1.asp
It's interesting. I plugged in Scorp's best time at his altitude and my same data here and our HP is identical. Hmmm, sounds like a dream exhibition match in the making :D:D:D
