    hi all

    im probbaly being very silly, but im not very mathmatically minded!.

    could somone tell me how to work out bhp per ton,

    or if its easier im after bhp per ton for the following

    300bhp(wheels) and car is about 1000kgs
    350bhp wheels same
    400 wheels

    i'll base it on a starlet.

    135 (hp) / 0.850kg (weight of car) = 158.8 hp per ton.

    i beleive it should be power at fly divided by weight of the vehicle.

    well 300bhp and 1000kg(1ton) = 300bhp/ton
    so u put the bhp on top and the tonnage on the bottom.

    like so

    300/1 = 300bhp/ton

    and so on

    350/1 = 350bhp/ton
    400/1 = 400bhp/ton
    or for example 216bhp in a starlet at mayb 860kg(0.86ton) is 216/0.86 = 251.16bhp/ton

    EDIT sx beat me to it

    yes it is with a starlet but somthing a bit different a special, dont want to disclose too many details incase somone else thinks its a good idea and does it!

    all i can say is it includes getting another car, making a starlet uber wide, and some serious power...

    You won't get much faster than 5.5 with WWD (Wrong Wheel Drive), especially without a LSD.

    with slicks you could easily get 4's to 60mph..... Im very confident if i put my slicks on i would get mid 4's maybe even better.......
