    Okay, now got it. The calculation is for torque to HP, or vice versa, if you have one of the figures....

    It's bcoz of the difference in the properties of the fuel...
    -Diesel is has more energy per liter than petrol.(thats why it has more torque & better fuel economy)
    -Diesel is more volotile than petrol. (thats why it doesnt need a spark plug)
    -Diesel has higher compression tolerance
    -Diesel cannot handle high RPM (small engines need high RPM, more RPM more power)
    - Diesel engines are less responsive than petrol engines
    - Diesel changes viscosity at low temperatures
    - Petrol engines quieter & require less maintenance

    But with advances in technology, the disadvantages of diesel power have been significantly lowered .Audi even proved that their R18 TDI Racing Car (Diesel engine) could win the Le Mans 24h race

    -Diesel is more easily combustible(explosive) than petrol. (thats why it doesnt need a spark plug)
    Have you tried lighting up diesel compared to petrol??
    Diesel don't need spark plug, because they run on high compression to ignite....

    sorry correction....misuse of words, its suppose to be "volatile" (not, easily combustible/explosive)..hence igniting at high compression

    i will go for HP then torque cos my car torque is too high de.. pening lah i drive... HP seems like the power is more constent.. Torque feels like the power comes in too big and too early.. just personal opinion... but both are great depending on your needs...

    High torque good for town driving, good pick up. If drive manual, less gear change....

    The thread was leading somewhere before it de-generated...haha

    Torque figures given are usually optimum at the rpm indicated.Put your stock car on a dyno and test with different gears it will be lower than the claimed figure and usually at a lower rpm because of the gear ratios.

    Question; both cars petrol and same gear ratios,final drive,tyres; redline7000rpm
    Car A:350Nm @ 3000
    Car B:210Nm @ 5000

    at the optimum rpm both have same hp BUT after that does torque 'fall off a cliff' and becomes zero...if so who or what is pushing the car.?
    Who will smoke who in a drag??

    figure this out and live a long happy life cheers :beer:

    hmm i guess the higher torque will win gua.. anyway i saw before a quote in one forum before as it interprets:

    >>>HP is how fast your car hit the wall and;
    Torque is how far your car can push the wall after you hit the wall<<<

    This is good quote.....hahahahahaha:biggrin:

    Sort of.. Hard to compare torque and horsepower..

    I see..i tot torque is how fast u'll hit the wall while hp is how far u can push. I use to think this way,
    Hp = strength, Torque = agility.

    the formula is :

    Horsepower = Torque x rpm / 5252

    so, actually the horsepower is limited by torque & rpm..

    any engine can get 1000 horsepower.. but can it stand the pressure or will it blow off ? :biggrin:

    Many already attained 1000 bhp. Veyron Super Sports now at 1200 bhp......
