Yeah...still missed the days when we had the Shell V Power Racing 100 12 years ago
My Evolution 9 was running 25 kw more at the wheels than guys with the same mods (exhaust only) and the tuner thought I had a freakish Blue Printed Group N 4G63 in it until I told him it was running on 100 Last edited by Karmic Man; 10-03-2018 at 01:17 AM.. |

I want to see overlay with E92 M3. 😭😆
The ~350whp eventually at 8.2k rpms must look tragic. 250 flat torque looked nice through about 2012 though! |

Then E92 M3 must have only 330 crank hp.

Yes, Dynojet reads higher than other dynos. I made a pull on a Mustang dyno and the operator had it set to simulate Dynojet. The numbers came up about 10% higher.
So in my experience: mustang dyno - add 15% to get crank hp, Dynojet - add 5 % |

Crank HP will always be estimated on a chassis dyno. You're best off multiply by drivetrain loss which is 15-18% for an automatic rwd. MDs do typical display more "real" numbers. Dynocom/jets are inflated. Once again, dyno numbers might as well be a moot point. Run the car for "real" numbers.

Would be cool to see M2 vs. M2C vs. M3 vs. M3C vs. M3CS on the same dyno chart. Guess you may as well throw in GTS as well.
It would be very interesting to see what potential is available from BMW's "stock" tuning on basically the same engine. |

I can't imagine any of us ever going WFO (dyno-mode) at 2k in 4th or 5th gear. The dyno plots will never show anything about part throttle "responsiveness" or driveability which is what I think most of us are talking about when we say an engine feels torquey down low -- it's responsive at part throttle and low RPM is what I think we are trying to characterize about the M2. Can't tell that from dyno plots |

could this also be the reason bmw coded out the low end torque from the m2c/3/4
to avoid spun crank hub? Quote:
