I took my M-Coupe to Woodbridge Dynotech (Woodbridge, VA) to establish a baseline before I install the Supertrapps. The results were delightful. I disconnected the battery before run 3, but I had previously 'initialized' the car pretty well...

HP: Max RPM
Run 1 215.5 6100
Run 2 217.0 6150
Run 3 216.8 6200

Torque Max
Run 1 226.1 3900
Run 2 226.7 4000
Run 3 226.8 3900

Using the typical manual drivetrain loss of 15%, that would mean its making about 254.6HP and 266.5ft/lb torque at the flywheel. This is stock: no chips, no software, and no mods other than suspension. Just barely in the high half of the -1% to +10% range BMW quotes for the car.

The consistency of the data between the runs is also excellent, far better than I expected, but it was a nice cool day too (intake temps of 54.3, 56.9, and 57.2). Torque breaks 200 at 3200 and stays up there until 5600; 210+ is from 3500-5000, 220+ from 3800-4300. At 2200 it was making 170. HP doesn't break 200 until 5000. With the car in 4th times from 2200 to 6400 RPM were 11.29, 11.27 and 11.28 seconds.
