does anyone know how to calculate wheel hp from the standard hp??
ex: what's the wheel hp of a stock 200hp accord V6?

Usually, a manual tranny will give you about 15% power loss... and an auto tranny will give something like 22.5% power loss.... I'm sure there are alot more factors involved.... but this is a general rule.... if you want to know the exact power... you need to take a look at DYNO charts...

I'm not sure i know what you're talking about.... but.... i think i do...just divide the power by the weight. And then you get some fraction.... and that's your power-to-weight ratio.... but that doesn't mean a damn thing until you compare it to other car's power-to-weight ratio.... (and the ratio is how much power per pound, so the higher the number the better)....but that still doesn't mean anything until you put into account gearing, aerodynamics, power transfer, etc...
