It is the overall energy that is relevant.

The conversion from alt-charger-dump battery-controller-motor is less efficient than a turbine/backpressure or belt-gearbox/drive losses. However, for the same wheel output boost/flow required is ~ 1/2, therefore 1/2 the energy, than that of conventional FI due to minimal parasitic losses. It is when the parasitic energy is extracted that determines the difference in efficiency in a DD application.
Conventional FI...@ 11-12 AFR. Phantom ESC... @ 14.7 AFR
