^This. That combined with the lower WHP to higher WTQ numbers when that should be reversed. It seems odd. WHP is definitely too low for 127-129 MPH traps at 4300+ lbs. Could be the test. Could be a limitation. But it is off.

Since F90 has AWD I assume 120 should be easy even if not launched well. So I say if he can trap 120 with ease then I think the car has no problem. |

Seems like a red flag to me. Even if the WHP was lower than we thought - the WTQ should have been lower than the WHP number. |

Sorry for the typo numbers corrected the AWD numbers read higher as can be seen on the pring outs
450 RWHP/481 RWTQ (W/front wheel load) 471 AWHP/509 AWTQ Mustang Dynamometer is the most accurate and reliable dyno because it provides real-world loading and precise control. According to their description. Now for bragging rights Dynojet is THE MOST POPULAR DYNO IN THE US. This is why we started with Mustang. I’m sure a Dynojet run will be up soon but for now we’re the first with any data. Eventually we will run on a Dynojet as well with higher number and for the cherry on top, Dynojet is still lower numbers than the flywheel 15-18% When upgrading parts it is recommend to dyno at the same place for a better idea of actual increase after each Mod . It will never be perfect due to elevation tempature and humidity and other variables as well as the correction factors. In the end were just providing our own cars info im sure there will be other people posting soon. I’m yet to see the same car number between machines (dyno jet/mustang)usually it’s one car on one dyno and another guy across the country with the other dyno Dynojet numbers coming soon. |

All understood - why do you think WHP is reading lower than the WTQ when crank output states HP is higher than TQ (600/553)? |

Considering you are limiting the revs, feels like that could make for an awfully long and boring weekend!

There was a lot of nonsense here-say over F80s too and I can tell you flat out that mine wasn't detuned and it didn't get any faster than my first autobahn pull until I jb4'd it, 1200 mile service or not. The fact that the car "logs" and "yellow flags" the first service, and even if the speed is electronically limited initially has no bearing on whether the software is physically limiting the power output. Like some other guys are saying you're purely speculating. You have not "seen it in the code" you've seen the other non-correlating data in the code and you've made the assumption that what you believe is correct. Textbook observer bias.

Okay, you make a valid point.

The Mustang dyno may read 6-8% lower than a dynojet on average - but for a RWD car - new cars - you are only looking at 10-12% as they are more efficient now. AWD 12-15%. Maybe 18% at the absolute worst. I am not too sure about this groups testing. I have asked three times with no answer why their WHP numbers are lower than the WTQ numbers when we should see the OPPOSITE. The number also do not make sense - nor do they equal the type of performance these cars are demonstrating (127-129 MPH traps at 4300+ lbs). I will wait for a Shop I know to dyno these cars - because as it stands - the results do not make sense. Last edited by vtknight; 03-23-2018 at 03:40 PM.. |

Running-in period limits the revs from going over a certain amount. Running-in oil is used in the engine and diff. The purpose of running-in period is to coat and remove component deposits (shards) etc. Once the first service ("Running-in Check") is performed, BMW reset your service indicator and delimits the engine power completely.
