Cal Poly Pomona used an electronic powered forced induction on their FSAE car in 2000 iirc. I think the major problem with it is the electricity needed to run a high power motor. You're pulling a lot of juice off the engine to keep the high powered motor running. There is no such thing as "free" power. You're pulling more resistance from the alternator to power the motor.
Newton had to be soooo smart with his laws of conservation of energy...
