Here is a thought for y'all.

Use the electric supercharger as a means to downsize your engine. The supercharger only needs to provide bursts of power when you really need it. Cut the engine displacement in half.

Now here is the kicker. Normal engines use a throttle plate to restrict the air available to the engine. Vacuum can do a certain amount of useful work. With an electric supercharger you have the potential to use it as a generator when it is not providing boost to the engine.

Throttle restrictions to control engine speed create no energy, while the electric supercharger could provide a means of capturing energy from the same effect as a throttle plate. Control of the throttle would be by the amount of load you applied to the generation phase of the electric supercharger.

Not sure if it would be enough to provide all the electrical needs of the vehicle, but if it was combined with a small Rankine cycle power supply using exhaust heat it should be able to drive every accessory on the vehicle.

I am not an engineer so the technical calculations are beyond my capabilities, but you can't argue the fact that using available vacuum to create electrical energy, compared to normal throttle plate losses, is in fact free energy.

This would beat any other presently available supercharger or turbocharger option. Also consider that electrical power generation would be continuous, any time the engine was running, even when there was little or no manifold vacuum. That's free energy for supercharger application, at least to a certain point.

The supercharger would have to be a positive displacement design, unlike the one shown in this thread.
