I'm not certain I follow the logic with reduced pumping losses - you're pumping more air through the engine, not less, right? That energy is still coming from somewhere.

Pumping loss in spark-ignition piston engines is the power required to perform their intake and exhaust pumping functions.
^ I mean, if you using grid power to run the supercharger, sure, the energy being used isn't coming from gasoline, but you could also just use that power to directly drive the wheels. The fewer steps between, the better. Ideally you'd have the electric assist after the transmission to reduce losses even further, but fabrication gets difficult. Maybe you could put a pullet on one of the CV axles?

What am I missing?
