Reason I'm guessing low ~320hp is due to the fact that it has been stated many times that this car has to be slower than the M3. What I'm thinking is that this car will have all of the handling enhancements (lsd, wider track, better brakes, weight savings) but only a modest bump in power. It shouldn't matter though, as tweaking HP out of the N54 is no big deal.
