here's another one that i've mentioned before


hp = weight * (trap speed / 234)^3

That's rear wheel horsepower.
when i did my math for my 69 nova at 125mph and 3180 on race day i came up with

hp = 3180 * (125/234)^3

484.74 rwhp

when I went to the dyno the car had 456 at the wheels, but it flattened out at the point where my clutch couldn't hold the tires anymore. going to the dyno again sometime soon. maybe today if i can. better clutch, more holding.

try this one, you can chose between flywheel or rear-wheel HP #'s, but you need to know your nova's weight.

thank you so much for posting this, i just reformatted windows and lost my favorite links. i couldn't find this to save my life.

this one has always worked good for me however i made my own off this guys source code. it has a 17% drive line loss. i always used it my hondas which have about a 15% loss.
