So the stock rating of 352 hp... (PS).. I show that converts to 347 hp...
and the 332 hp (PS) at the wheels converts to 327 hp ... which means the 1M puts out at the wheels nearly what it is rated at the flywheel from the factory!

IIRC the Automobile mag dyno runs show 293 hp at the wheels for the N54is motor?

I'll be interested to see when Automobile throws a 1M onto the dyno for an apples to apples comparison to show what sort of work the M engineers did to tweak the 1M beyond the 335is/Z435is.
