Why do you think BMW rates the N54 at 300hp instead of where it really should be which is around 333hp or so? I love my E46 M3 but I would have rather seen BMW keep the S54 and work on putting the M on a diet. I will be more than happy to beat down E90 M3 owners in my 'lowly' 335.
The S54 was at the end of its line. No room for extra bore, piston speeds too high, etc., etc. Totally maxed out. Not way to compete against 911, RS4 and AM Vantage without the new V8. Keeping the S54 would have been a terrible decision from an engineering AND marketing perspective.
"Beat down" E90 M3 owners in your 335. OMG get real. Maybe in a drag only, maybe to 60 or 100 with
a Vishnu tune that is not even available yet. You are in fantasy land on this last statement.
