    It depends on the application.
    But for most it´s fine to just note 15% loss for RWD cars.

    So 321hp should show cirka 272hp rwhp.

    And people wonder why there are so many hyped up bhp figures flying around

    My Mpowered Touring certainly won't be 286bhp at the rear wheels, that too is at the fly wheel
    As other have said you can expect a 15-20% drive-train loss on a RWD car. The Evo's were never 321 bhp either, they were 321 PS which works out at about 316 bhp. That was for a LHD drive one as well so 10-15 years later a good figure for a evo is around 310bhp at the fly. You can get 340-350 bhp at the fly out of a Evo with tuning but that's pretty involved and will cost thousands.

    Here's a guys rolling road print out on a standard evo, from someone I trust. 1996 E36 M3 3.2 Evo - Power run

    As for a ECU to run a turbo'd car, have you seen this thread? Turbocharged E36 M3

    Yep, i thought vauxfan was abit off. Also i hear that there more reliable if the vanos is removed, Is this a better option or are there more cons than pros in doing this?

    They will only be more reliable in terms of the vanos unit failing or not failing.
    Nothing else with the engine will change.

    You will loose low end without vanos, there is no question about it also some spool.
    But instead you can run a much cheaper ecu solution.

    I should hopefully have something later this year for S50´s in terms of ignition and fuel control for boosted applications.
