    Hi guys,

    Have decided im going to get my car dyno'd in a few weeks and am wondering what the deal is with the m42 motor being quoted as 140 bhp - is that value at the flywheel, or is that what is being put down at the wheels? Also, has anyone had an older (early/mid nineties) car tested and what like were their results compared to factory quoted figures?

    Cheers

    140bhp or so will be @ the flywheel, power at the wheels will be far less.

    My 318is (140 bhp) fitted with de-cat, Scorpion exhaust, induction kit and Superchip was Dyno'd at 133.5 bhp at the flywheel

    I think it should produce just a little bit more these days

    Let us know how you get on please

    Cheers guys. Will be getting it done when have a little bit more dough kicking about.

    Just wanting to see becuase my car does seem rather quick, im not a boy racer as such, but as is the case when we all say that, it doesnt mean we never, well, race. On the (I hasten to add rare) occasion of said 'race' I am often mightily surprised how well my car keeps up. So either my cars faster than it should be, or these other guys cars are fooked

    Will be interesting to find out.

    In all seriousness though - and don't think ive ever said to you mate - your car is not only stunning, but truly inspiring as well. The perfect e36? Its definately up there

    2 months later and the deed is done. I have never had any of my cars dyno'd before, the noise was deafening

    Unfortunately, the results were disappointing.

    The car pulled very cleanly from ~1500rpm, but the final result was only 118 flywheel h/p, @ 5420rpm.

    The run was done twice, both times with the same result. According to the machine, after hitting 5k rpm, the car would began to begin to run lean, and the power graph levelled off, actually dropping a shade, before picking up to its maximum value @5420, and then dying off again. Funny thing is, this seems right, everyday driving is not above 4k, but I do know that when I give it a spanking, the power feels like it peaks at ~5k, meant to peak at 6k is it not?

    Does anyone have any ideas of the main causes for an engine running lean at high RPM? Fuel pump, fuel filter??...

    Also, I don't have a scanner to get the printout up...

    Cheers

    Massively disappointing engines in my opinion - my '93 MR2 2L N/A was put on the rollers 2 years ago and made 4bhp more than the factory figure 15 years previous at 159bhp fly with just a filter and a back box. The car had lost NO bhp over its lifetime and the dyno guy said most MR2's he had tested were the same.

    Just use my 318is for commuting - there is no point chasing power gains out of it! lol

    lean running at high rpm can be pump/filter but is more likely an injector problem.
    you could try these folk http://www.asnu.com/
