Not to mention a lower redline, from 7500 (S55) to 7000 (B58)

Heat dissipation issue aside, they will have to lower the compression ratio (11.0:1) of the B58 to increase boost + bigger turbo to meet the power goal. Max rpm will still be at 7000 rpm The S58 with a larger bore and shorter stroke than the B58 can only manage a 7200 rpm.
I think the the redline is more to do with the zf auto transmission?
