Hmmm... Of course there are a plethora of factors here. But in just going to hush and wait for my car to come in. One month to go. |

Something doesn't add up...That is well over 20% loss. They did say something about the car's computer kicked in when it detected something was off (Fuel?). I hope there is another dyno test soon to baseline the results. Not that I car that much as I will enjoy my car regardless!

It's an Australian Dyno Dynamics chassis dynamometer. These provide lower figures than most and they advised of this in the feature. The car did make the rated torque on their machine however. |

I think that the pull was so looooooong that the overboost feature probably ended during the pull and torque fell off substantially. Hp follows torque naturally ... So the top end fell flat. It's not called a " heartbreaker " Dyno for nothing. It's that particular type of Dyno. More Dyno tests will come. I personally prefer Dynojet. |

They dyno all the cars above 1 mile of the sea level, also they used low octane quality fuel, and that also adds to the factor why hp was so low, and why computer had to re-calibrate things.
So, overall if terms were fair, I think it could easily pull 330 at the wheels. |

By no means am I a Dyno expert. Here are a few questions I have.
1. They used 91 octane (BMW recommended) but I feel 93 would have yielded slightly better results (+1 maybe +2?) 2. Does anyone think if they put additional fans on the fangs that would have helped? 3. That was a nightly long pull as well. More videos to come of dyno'd M2s hopefully. I was expecting it to at least break 300. And I was hoping for low teens. |

It would have been good if they could have shown the results for the M 3/4 and the RS3 under the same conditions,although 300 at the wheels equates to 370 at the crank,so taking into effect the fuel quality and ASL specifics and the fact the dyno tells it like it is,its not that far out,although still disappointing if " that's all she wrote " |

We have 93 here all over. So we will be good. I would love to do a 93 run and some 100ish to see how far the DME learns up with timing.

Is it possible, that something needs to be done at the dealer, post break in? I know for the DCT cars, launch control is disabled until service one.
Just a thought... Results do seem lower than expected. |

Once the tuners get a hold of this M2, I think we will definitely see some e85 in this car

Perhaps an appointment with Mr. JB...........4 wouldn't go amiss

For some perspective, I had my m235i dynoed on a Dyno Dynamics at sea level in a 10C ambient room and got 316hp (crank that is, 266 hp wheel adjusted) stock running winter tyres (no where near ideal admittedly) that did need to cool down between runs.
With JB4 running map 2 on 93 octane fuel it was putting out 349.6 hp (crank) and 381.2 lb-ft of torque (crank). Its going back on soon with summer tyres and sport cat. Will report back on this. I think people may confuse correct/ realistic with overinflated "wheel horsepower" numbers that other dynos are set up to produce. Bigger is always better right? |
