Use a spreadsheet, draw some reasonable torque curves (say based on 1M, 335i or M5) and look at the resulting power curves. Just recall that in US customary units hp = torque x rpm/5252. Again given the F10 M5 has a redline of 7000 and that typically the M3 has a higher redline, 7000 should be considered a bare minimum value. From these basic ideas you can see that 400 ft lb and "about" the same power as the existing car along with a 7k redline just DOES NOT ADD UP.
