Of course it's more complicated than that; such as coupling the motor to the compressor, but as a concept does it look doable? It would most likely require some kind of raspberry pi / arduino box.  Anything y'all would add?

You’ll never spin fast enough to create boost. Boost isn’t added air. It’s pressurized air. Look up “compressor scroll speed” it’s in the tens of thousands. Like 70-80,000 rpms.

In reply to Trackmouse :

Well there we go. Follow up question? How does something like a procharger pull similar RPMs by operating off something spinning at engine speeds? Is it in the pulleys? 

edit: upon researching prochargers I found this 

it all makes sense now, pardon my ignorance laugh

Not to say you couldn't do the gears too though. You will need one heck of a motor. Like tens of HP. That makes a motor controller difficult too, because you will be dealing with huge current.

There is a very long thread on this subject on the FRS board. Over 500 pages in case you are bored. Google up "Phantom Electric Supercharger" for video and testimony.
