Z4M Coupe Dyno Results

[flimper]

Results of the dyno run I had today at Surrey Rolling Road. Saw a VXR Supercharged pump out 640 horses and a 135i produced 311bhp to give some idea of the conditions.

Is the bottom one the 'at the wheels' figure and the top one corrected for the 'at the flywheel' figure? 20% seems a lot for transmission losses.

I assume so, not technically minded

Sweet. Hope you enjoyed it - I find this sort of thing fascinating. Like that bump up at 6,500.

Did they fill all of the slots in the end? Were there any surprises for anyone?

I think 4 or 5 people didn't show up, I was nearly last up so didn't see much of anyone elses cars, I will look on PH later to see the full list of results

Is that not the Torque figure Carl?

Good figure! - nice linear curve.

No, I meant the one showing 343 BHP vs the one showing 280.
