    Enjoy! This is not a Piggyback!

    Same Day, Same Dyno, Same Car using APR's Engineering Test Methods.

    We are sharing uncorrected all wheel data, SAE corrected all wheel data, estimated crank data and the delta between each dyno.

    Testing days were in the 90+F.

    The APR RSC Exhaust was used during the stock and APR Beta ECU dynos.

    Did you measure the 23% drivetrain loss, or is that an estimate?

    Estimate. Since you have the wheel figures you can estimate anything you want. :)

    Someone is going to post those estimated crank figures as "measured" in the not too distant future, and the whole debate of "Audi engines don't deliver the claimed bhp" will rage on interminably.

    IMHO it would have been better if you didn't post estimated crank figures, just measured wheel figures. Or even better taken the time to measure the powertrain losses on the test car...

    If someone does, the debate is over because the 3.0T FSI put down WAY more than advertised.
