HP @ flywheel = torque X RPM/5252

261*4900/5252=243 M3
251*4900/5252=234 M Coupe 2001
228*4900/5252=215 M Coupe 2001

As the new motor holds torque longer the difference will continue to grow and be substantialy larger at 6500rpm, though the big difference come after this. Primarily do to lightened components (allows for safe high rpm) and improved breatability, which allows the torque to be maintained.
