The sensible thing to do would be to program the ECU to disable battery charging while the engine is under WOT or heavy acceleration. This would give a perceived power boost. Set it where the battery is not charged during normal operation until it gets down to around 11.5 volts. Then start charging the battery more aggresively.
I personally don't understand why we haven't seen a push to power the engine accesories (power steering, water pump, A/C, EGR stuff....) by small DC motor? A small 5 HP DC motor made out of rare-earth magnets would provide plent of torque for running all of your accessories at a constant speed, leaving all engine HP available for the drivetrain....
Our 3 does have a small DC motor to run the Power Steering.

A step in the right direction?
