cool idea but it doesn't look very cost effective.

Seems it'd be worse than a normal belt driven supercharger in terms of efficiency too.

"• Low-output alternators, which can't recharge the batteries quickly enough, can limit ESC running time."

i wonder how much power loss there is maxing out the alternator while this puppy is on booste?

I remember reading a test on one in a car magazine several years ago. Can't remember which and can't find it on the net right now. Most of the electric superchargers are only good at lightening your wallet. The one you linked to actually does work with certain conditions.
1. Multiple batteries - added weight with all the problems that implies.
2. Max use time of about 15 seconds prior to batteries needing recharge - similar effect to nitrous. You recharge on your vehicle, but this is not a constant power source.
3. High current draw so large, heavy cables needed from batteries to the supercharger motor/s.
4. Expense: initial outlay is substantially higher than nitrous setup.

Link to one site with complaint on their quality:

Oops! Too much boost. Blew something on the Altima. We took some visitors for test rides and some burnout photos, and after more than 30 runs at 10 psi, the engine let go. The fuel cut leaned out the mixture too much. Time to pull the head.

hmmm yea i guess even the electric supercharger isn't without issues... i'll stick to a VNT turbo thanks :lol:
