Does ((Weight/234)^3)*MPH estimate rear wheel or flywheel horsepower?

I think the subject pretty much sums up the question.

Thanks!

hp=weight*(mph/234)^3 estimates rwhp
also, et=1356/mph and rwhp=197*weight/(et^3)
These hp formulas are based on constant hp (which means constant acceleration) but they work surprisingly well for our cars, probably because of the very flat torque curves. The weight is total weight going down the track, including the driver.

Thanks Carl!

Cool, car was really hauling some a$$ this weekend.

RWHP = ((Weight/234)^3)*MPH = ((3700/234)^3)*143 = 844 RWHP

Thanks again!

You're welcome. You should have asked Sunday while I was looking over your car - very nice. Congrats on the new times, too.

Oh shoot, I didn't know you were there. Did we talk? So many people looked at the car that I didn't get a chance to say “hi” to everyone. In addition, many of those that I did say “hi” to I didn't do an introduction to catch there name. Even if I had I probably would have forgotten their names. I'm terrible with names, that's why I keep Richie Rezes around, he just seems to remember everyone....
