Went To The Drag Strip And Dyno On The Weekend.... - The Unofficial BMW M5 Messageboard (m5board.com)

At the track I took three runs with the M5 and here were the results:
1st Run: 13.5 @ 107 MPH
2nd Run: 13.4 @ 107.5 MPH
3rd RUN: 13.3 @ 106 MPH

The track conditions were fairly slippery so I am pleased with the times that I got. The car was fairly easy to launch at about 1200 RPM and slowly feeding out the clutch. The car has a lot of axle hop (especially during burnouts).

As for the Dyno run, I had to unplug fuses 13 and 20 in order to rev the car to the redline in 4th gear. I also tried a run in 5th gear and took it up to the 155 MPH speed limiter. The best results were: 345 HP @ 6200 RPM and 340 ft-lbs Torque at 4800 RPM. If anyone would like a copy of the dyno run email me at chaoticb@home.com I will be scanning the run later tonight. Just thought everyone would be interested to know how the car did.

Those are some serious numbers for rwh and torque. Obviously, if Ford does by BMW, Ford could learn about truth in advertising (e.g. Ford Cobra's hp deficit).

grammar correction "..does buy BMW", not "by". Man, the internet has made me sloppy.

Assuming a 15% loss to the wheels, which is conservative, that equates to 406 HP and 400 ft-lbs of torque. Very impressive. At 18% loss that equates to 421 HP and 415 ft-lbs of torque. Awesome numbers. I assume you have provided adjusted numbers for temperature. This corresponds to John Hennessey's test results. Obviously, BMW is conservative in their ratings.

Good quarter mile runs also.

Yes I did forget to mention that those numbers are corrected for temperature & altitude.
