So many things wrong with this thread - why are so many well educated owners/enthusiasts so delusional when it comes to dynos?
Dynos are only good for one thing. ONE THING. That is measuring a delta when modifying a vehicle when running the same car, on the same dyno, and either on the same day or on a day with nearly identical conditions. Other than that, the average hub or wheel dyno produces very noisy data. Taking any given dyno and saying, let me add 10, 15, 20% and that's my engines output is a useless exercise. If you want to know how much power a car makes, look at quarter mile trap speed, times, and similar results as the most consistent and applicable indicator. |

Found a bunch of posts on the subject. For example, a 2008 135i:
Dyno Dynamics (shop on the OP video used this) pull: 353.5hp/431.6tq. Dynojet pull: 404hp/461tq So you see, not useless number, but f**ing meaningless w/o reference for comparison (i.e. other cars, or before/after mods). http://www.superstreetonline.com/fea...ent-technique/ http://www.e90post.com/forums/showthread.php?t=891691 http://www.1addicts.com/forums/showthread.php?t=214597 http://www.corvetteforum.com/forums/...-dynamics.html http://www.evolutionm.net/forums/ven...s-dynojet.html http://mbworld.org/forums/c32-amg-c5...r-results.html http://www.gtrlife.com/forums/topic/...cs-vs-dynojet/ http://www.camaro5.com/forums/showthread.php?t=352839 |

One of the draws of the m2 is that it isn't as overpowering as an m4.... I don't get why people are so concerned about ultimate power and upgrading turbos etc.. I don't think that's the point of this car.. Plus if u want ultimate power the s55 with all its cooling is a far better choice ....

Yes, and we already have at least 2 professionally conducted dragstrip measurements conforming (unsurprisingly) to BMW's advertised power numbers.

Yep, but not a single customer or even HEA car has been magazine tested correct? We don't know until we test.

I'll repeat it again here. Chassis dynos are inherently inaccurate at producing absolute power numbers. This is what counts:

If we are to believe these numbers it makes the M2's performance awfully impressive. Motor trend did a track race with the M2 versus the M4, same driver, the M2 turned faster laps. Also the M2 was within a 1/10 in 0-60. Both cars effectively weigh the same so something doesn't add up.

Guys, the car is quick. It feels great and is almost certainly a little underrated according to my highly sophisticated but dyno. My 3300lb wrx put down 354/381 on an AWD dyno and it's very similar to that. I do have a DCT though..
This car with a tune and downpipe will be pretty beastly I'm thinking. I will dynotune it once I have 1k miles, not that it will mean anything! I'd just do it to see the gains over stock. |

Yes, I don't know why they didn't test the DCT but their test says it was the 6mt.
