Electric Superchargers (No, really...)
I see alot of electric "Superchargers" on ebay and such that looks like that probably actually reduce power, but it got me thinking... why wouldn't it work in principal?
Does anyone know how much power is required to operate a supercharger?
With new (and cheap) brushless electric motors than can output a ton of power at high rpms... it seems like it might be possible to build at least a low boost system that uses a small high voltage battery pack that is recharged slowly from the main automotive battery.
My thought is to use (3) 1600kv motors (max RPM is 57k, 5HP each) in a star pattern around a main gear which is used to turn the supercharger. The advantage would be no parasitic losss when not in use and can be put in any position in any vehicle... If i were to use highoutput Lipoly cells, it could run the super charger for 2-3 mins, and then be recharged in about 30 mins.
What are your thoughts?

If it really worked, engineers would already be all over this. Trust me. I don't know about here, but it's been explained ten fold on other forums I've been on. Just do some hard research, and you'll find exactly why not a single sould successfully runs an electric supercharger setup anywhere in the world. Your vehicle's electrical system could by no means keep up with the drainage a brushless motor like that would produce. The alternator would put such a load on the engine to create the amps for these brushless motors, that you'd essentially have a pile of **** for an engine by the time you properly fed all of these motors. It takes HP to make electricity. 100 HP is like 75KW. Say your truck does 14 volts. 100 HP = 5,000 amps from the alternator to power such a supercharger. 5,000 amps / 120 amp alternator = 41 2/3 alternators, just for 100 HP. You'd be better off buying a NOS sticker and a big spoiler. On the other hand, you could've just bought my NX kit for $325 shipped. It would get you 150 HP, last 2 or 3 minutes, and be filled back up in under 30 minutes. Just saying.

I think this is true, and the key.
However, how much power does it actually take to make usable boost?
I am aware of the electrical properties and requirements. I am not one of these people that think I can run my vehicle on water by performing electrolysis to get hydrogen... powered by the car battery. lol. It certainly would not be powered with the car battery, or continuously. With the idea I was talking about before (No idea if 15HP/10kw of boost creating power would do anything?) would probably be run on a 45C 36v-55.5v lithium pack capable of the discharge rate, then slowly recharged. It would have to operate more like a nitrous system.... (not constantly)
Anyway, I am sure you're right - if it were possible it would be all over. Still interesting IMO though. Would be interesting to know how much HP is required for a certain amount of boost....
