    bhp of a scooby

    my mate just bought a 51 plate scooby wrx does any 1 know the bhp of 1 and also am i right in thinking a 4wd looses more power than a front wheel drive got a feeling it around 25 % for fwd and 40 % for 4wd

    power wise they are circa 215bhp for the wrx.

    there is always a big debate about how much power is lost in a 4WD car.

    the most effiecent drive is FWD as the length of the drive shafts are shorter.
    4WD is the least effeint as there is more unsprung weight for the engine to turn and also the extra drive shafts diff transfer box extra add a lot more weight.

    its like any thing in life 4WD give increased traction by as a trade off more power is lost.

    Not quite, depends on where the engine is. If like a porsche, the best drive would be the back.

    For a mid engined car, it is a mixup between the backs and all four

    Just thought i would be picky!

    (If this doesnt makke any sense, it is because i am as high as a kite because i have been doing some spray painting, and forgot the ventilation side of things!)

    Sorry!

    thats very true.

    I was only only really thinking of front engined cars.

    suppose if i was being very PC i should have said that the close to driven wheels are the engine the more effeinent the power transfer is

    I, finally got my vision back to what it should... was a bit blurry earlier! Wouldnt recommend inhailing paint fumes to anyone unless they are looking for cheap/dangerous thrills!

    Anyway it is all to do with the polar moment of inertia, which is why a 4WD /AWD (There is a difference) will usually bog down on a quick start.

    Stick that in your sports exhaust and light it up with some N2O Mr Scoobaru!

    Depends on the BHP, UK spec scoobys are pants...thats why everyones like OMG I beat a scooby. With exception of the RB320, P1. The 2000 Turbos are pants, as are the uk WRX and STI in comparison to the Jap versions.

    we get dumped with shit interior and trim aswel

    not the most scientific approch but this may help.

    going by my rolling road figures my subaru made 300 at the fly and 235 at the wheels

    so that makes roughly 22% loss.

    interestingly tho just dug out the results for the astra

    108.2 at the fly and 80.7 at the wheels

    making it roughly 25% loss again.
