Let Gayle Banks work the engine for maximum power under boost, while retaining the best BSFC map for the normal operational range.

Now you can operate the vehicle at best BSFC and get much higher mileage than the present configurations.

The supercharger would operate a very small percentage of the time, and with the engine running at close to 40% thermal efficiency you could get 40 MPG out of the truck. Alternator loads would be greater depending on percentage of operating time in boost, but the alternator would be extracting energy from an engine at its highest BSFC point.

Best of both worlds, with no necessity for any additional components, except a larger battery and the supercharger itself.
