Anyone know German?
I have always told my customers, that the absolute number means very little. It's the delta that is important, and the area under the curve. Our dyno reads retarded low, but we dont care..it's great for steady state tuning, and our cars are faster.

highly agreed.

...and until someone, somewhere comes up with a dyno protocol that everyone follows, it's not realistic to compare one car to another since lots of people dyno different ways. i.e. pulling in different gears on different dyno machines looking for which one gives them the best numbers to brag about. Until then, dynos are really best to measure personal gains and are only truthful when tested while all other vairables are the same such as the same dyno, from the same gear, ideally at the same temperature (although not always possible), altitude, etc. If you bolt on a part, and keep doing pulls different ways to find the gain you want, you're cheating yourself. But we is smart people and we be knowing that already

MaHa dyno sheet
http://www.goodspeedperformance.com/...g37%20cobb.pdf
my drivetrain loss is 81HP!!! Damn! I don't know about the other number because they are uncorrected. I don't even know what a stock G would make for a comparison, or what my G made before the partial cobb tune. I really have no answers, just this cool dyno sheet that reads lightyears lower then any other dyno I've ever been on. Oh Well

AG I think your Maha dyno HP #s should be ~10% higher because the dyno only shows HP peak at 6900 rpm when you can go to 7600+ rpm with your mods.
The parasitic losses calculated could also be accurately recorded with Automatics vs Manual Transmissions.
These results look very convincing. I also like the way the results show rotating mass values! Thanks for the write up!
