Due to the strengthened internals mostly, only on the M performance models. Are the engines stamped with their code? Has anyone checked?
Also from what i have read it was only 10 kW difference in output 0o0 to 0T0

Not sure on the N55HP designation.
If the 0O0 to 0T0 is only 10KW, how in the world can they get to the rumored level of 365-370?
I had been basing my comparisons on the original N54 to the one used in the 1M. Now the original N54 was famous for being underrated, but I believe that the 1M was also dynoed at levels where the crank would have to have been higher than 335 BHP as well.
I have just never been impressed with the N55, and I am really hoping that BMW works some magic on it. In full disclosure, I haven't driven a new M3/4 with the S55 either - so maybe that version of the 55 (with 2 turbos) is more satisfying.
