Different dyno... this has been discussed... the other dyno is not measuring power the same way.

not all dynos are created the same.
Call me a snob.. but I prefer Dynojet.... Mustang's dynos are also cool... but anything else I really can't be bothered with. Cool to see the multiple pass runs that they recorded as well.. Outstanding thread. Amazing photos. Awesome attention to detail all around. Last edited by M3 Adjuster; 06-28-2014 at 02:32 AM.. |

CO2 emissions in g/km 204.0 [194.0] [1] Combined (ltr/100km) Combined (mpg) 8.8 [8.3] 32.1 [34.0] [1] Cylinders/valves per cylinder 6/4 Capacity (cc) Capacity (cinch) 2979 182.00 Stroke/Bore (mm) Stroke/Bore (inch) 89.6/84.0 3.50/3.30 Max output (kW/hp/rpm) 317 (431)/5500-7300 [2] Max torque (Nm/rpm) 550/1850-5500 Compression ratio : 1 10.2 I dunno... Looks like you guys get the shaft w HP again...lol... If we take the above figure from BMW site and extrapolate your dyne run, it comes to ~ 482bhp on 97-101 octane in UK. It felt immensely faster than the e92 M3 I used to drive to the dealer before the test drive... |

Can someone explain me howcome dyno results differ by those official stated by BMW by that much?
I don't believe that BMW doesn't know how to check and dyno their products. It is also weird to me that NA engines always come out under rated opposed to FI engines. Any thoughts? |

BTW, BMW said the new M4 is about 176lb lighter with 6MT. 132lb lighter with DCT. Last edited by CanAutM3; 06-28-2014 at 09:30 AM.. |

I have a hunch it has to do with testing standards and methodology when manufacturers establish their ratings. But I have not yet put the finger on the exact technical explanation. Last edited by CanAutM3; 06-28-2014 at 09:31 AM.. |

Second, in your post showing comparison numbers between the stick and DCT, you used three tenths of a second for shift speeds. Way back when, we looked at shift speeds with an accelerometer, and deduced that two tenths was the actual shift speed, across a couple of speed-crazed drivers (with me being one). Best shifts were in the .18 -.19 second range, but two tenths seemed close enough. Last, does your software allow for powershifting? If so, it would be interesting to compare a two-tenths, powershifted MT against a 55-pound heavier (according to BMW) DCT. Not trying to prove anything here (DCT will still be quicker), but just curious. |

Given the fact that I always take dyno results with a grain of salt, I must admit that I'm impressed with the numbers this thing is putting down on 91 pump. I wonder what 93 will make or e85 for the brave ones who go that route. |
