The power demand of an electric supercharger is in the same ballpark as a starter motor. In fact, you might be able to use a starter motor for the job, if you geared it up enough. The system certainly can't provide "continuous" power at this level, but it can certainly handle, say, a 20 second burst at WOT.

I would use, like, an electronic regulator that starts adding a pinch of boost at 60% throttle, a couple of pounds at 80%, and whatever upper limit you want to set at WOT. You'd need a motor controller (not a cheap item), and it might help to create a secondary battery system that takes power from the 12 volt system to store a 96 volt charge. Otherwise you need a really beefy controller box, like those used in smaller electric cars, just to handle the amps, though the total power is small by its standards.

Or you could just switch it from off to full power at 95% throttle, NOS-wise. Save hundreds of bucks by giving up the pretensions of being smooth like a turbo.

Where an electric supercharger could really shine is in a hybrid car, which already has a high-powered electrical system. Combine it with an exhaust turbine powered alternator, and you have a decoupled turbocharger. That's the system I want to build: a hybrid with a turbine alternator.
