1M Dyno Results
 
BMW has hinted many times that they have under rated the power of the 1M, but it now looks as though the published numbers from BMW for the 1M equal real life Rear Wheel Numbers.

This is one very strong engine!

Pretty well right in the middle of the M3 and 135i. I wish they showed the chart.

Got to love that torque number!

Uh, not for nothing, but how is this news? The 335is and Z4is have been out for a while; should be plenty of dyno info out there for this motor...

Dyno curves remind me a little of my old chipped S4. That car had a nice flat torque line...

The M guys tweaked the N54, not just ECU tuning, but some new internals including redesigned piston rings and other stuff. The 335is and Z4 have never put up dyno numbers like this, AFAIK.

~402 hp at the crank if you subscribe to the 18% driveline loss theory! That's perilously close to M3 hp numbers there.

My 335is dynoed at 319whp on a DynoJet with 93 octane against the 320BHP that BMW advertises it at. Saw the 1M dyno at 331whp against the 335BHP that BMW uses. So the 1M is stronger & in proportion to the advertised spread. It would be a bit more of a tune in the ECU because just about everything else is the same.

Main thing is both numbers are bogus because using the CHP/BHP scale they both are under-rated quite a bit.
