You guys say it is too much work/cost for what you get...
But (besides the obvious that it would be a rigged up POS) why couldnt you strap a leaf blower under the hood and run it off a power inverter/battery/whatever.
That idea would be for WOT racing apps or something, obviously not R&D'd enough for daily driving.

Well, I found a ducted fan unit that will move 3000CFM... I'm tempted to put it in and see what happens...It's hard to imagine it wouldn't help at all, especially at low rpms... I should get one and play with it... and if/when it doesn't work.... install it in a ridiculously fast R/C airplane. 
It produces around 10lbs of thrust while moving 3000CFM, and is 3.5" diameter... the area is around 9 square inches, so I don't know if it works this way.. but that leads me to believe it would build up a little more than 1 lb of boost. I am not sure what good 1lbs of boost would do? (Anyone know?)

Theres a Company that takes the cold side of a small turbo and installs a large, high rpm electric motor on the other side turning the shaft..They sell them for $500..I know of one video out where a 1.5l motor made 2-3 psi and picked up 35hp...Nitrous really does the same thing you are looking for if you think about it....and works

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.

those electric "superchargers" exist for one reason and one reason only...to empty the wallets of gullible and ignorant people. if you want to make more power, do it right, it will cost money and take work but you will see real results.

Didn't read all the posts so excuse me if it's already been said but what if instead of battery packs use a converter to like 120v? I had a procharger head unit that screamed when I put an electric drill to it. Drill just ran off of the house plug and was variable. I have used the same drill with a 12v converter and still spins the same rpm and torque. My way is different then I guess what everyone else is and instead of using amps that suck down the alternator change to higher volts. If it were any way possible using a procharger would be the easiest. That way you just find a high torque drill that spins around the same rpm as a engine and let the gear train in the procharger unit do the rest. Idk just thinking out loud. Would be kinda fun to mess with but I still prefer still doing things the regular right way lol.
