    Lol, it's worse than you think!

    328 was about 193bhp and the 325 about 190bhp. I say about, as there is some confusion over what figures are quoted in PS and what are in BHP. PS is an obsolete measurement for smaller German horses!

    The M3 Evo is 321PS which works out at about 316 bhp. However, it's accepted that a good evo is meant to get just over 300bhp. I suspect that this might be because they need their clearances spot-on to get good figures. In fact I have even heard rumours that BMW tested the engine without any ancillaries to get the stated output but I don't know the truth of that.

    Before starting the power run they said that they'd expect a WHP of 235, but in there experience this wouldn't be achieved.

    I was assuming power loses lost through drive train would be measured rather that calculated? surely to assume a standard loss of 17% is a little inaccurate? Although a loss of 33% does sound high?
    As I understand it (and Im no expert) they dont just randomly add 15% for FWD, 20 for RWD or 25% for AWD. I think they calculate it at the end of the run by putting the car in neutral and letting the rollers wind down on their own for a bit and from that they measure how much drag there is through the hubs/dif/gearbox etc and in some arcane manner from that they can derive a %loss (for that particular car on that particular day on that particular run) which they then apply to the ACTUAL measured RWHP, this gives a APPROXIMATE FWHP figure which is obviously higher and makes people feel better about themselves and their cars.


    P.S. Disclaimer - That might all be bollocks as Ive never dyno`d a car and am only repeating what I have read elsewhere(from memory)

    Sure, the point was that the calculation can be fudged and if you are getting told there's a 30%+ drivetrain loss it might be worth questioning it!

    absolutely - might even be a sticky brake caliper or low tyre pressures even

    We could always see what date Mark is due in and arrange it so that he can be there too

    More the merrier and besides the later we leave it the more chance I've got of getting the coupe there
