[Shovelman]

A turbocharger or a supercharger is a compressor that is not able to deliver the right boost at all times. Sometimes too little but most of the time it is more parasitic drag than is needed. It spins too slowly with the throttle shut and takes too long to spool up.

Why not use an electric motor to spin the compressor? Motors have come a long way in the last few years, they are lighter and more powerful. Controls have reaches genius levels.

The motor would be sized to support full rpm so at lower rpm it would have plenty of torque to ramp up very quickly. Or it could be spinning fast all the time but with an intake valve so it would be spinning in modulated vacuum.

The alternator would need to be bigger to support the motor but it could charge only when the power is not demanded for hard acceleration.

1. Minimized parasitic drag so more net power

2. And more fuel efficiency

3. The perfect boost available all the time so more power and torque at all RPMs
