you need a lot higher voltage to put out the crazy power necessary to compress massive amounts of air really quickly. current brushless motors about the size you'd want in a turbo/supercharger/nutty electric hybrid thing (like a 700 size rc heli motor) can make 6-12hp, and they weigh very little. i'd call it an eventuality at this point... just a matter of time before it's possible, then some day practical.
it makes sense that it would be best used to spool a turbo, since keeping up with the airflow demands at high rpm would require a ton of power (and generate a ton of heat).
