ok here is my question
i've heard a lot ppl say use the weight of your car divide by your hp then you'll get 1hp = to how much pounds that hp has to carry, the less pounds you get, more faster ur car is, but my question is i've compare my ITR to my firends BMW540 supercharged from dyno, and we use the forumla, appearly my car 1 hp carry about 0.32 pounds more then my friends car, so does this mean if i race him i'll be close to him ?? as result nope he pulls me really bad, more then 10 cars distance.
does this have to do with torque ?

 

" it doesnt worth a penny"

Please fix that. And a supercharged 540 will outrun a ITR anyday no matter what math equation your doing.

 

i think a stock 540 would hand us bolt on guys our asses, *** long as its a 6 speed....

 

e39 540s? interesting

 

Torque and the cars gearing in relation to its powerband. Your peak hp to weight ratio might be better but his under the curve might be far superior.

Also be sure that you are not comparing his WHP to your flywheel hp.
