Do the math: our customers with NOS go through 3-4 bottles/week, and at $30 to $45 per bottle, that's from $4680 to $9360 a year in refills. In contrast, if you install our ESC400 and upgrade your alternator to a 200+ amp unit, the system can regenerate at a 10:1 ratio. That means if you race two 15-sec runs, your system will recharge in a matter of minutes at zero additional cost.

If you have laptop in your car that says "DANGER TO MANIFOLD", you're gonna need AT LEAST 6 or 8 bottles a week.

Re: Finally a real electric supercharger that works.
A 200+ Amp Alternator would "steal" power from your engine through the added frictional losses on the belt and you would lose power whenever you are not in "boost".

So it is an electric motor driven Eaton Blower? Interesting
I wonder how heavy it is by itself?
I also wonder what a replacement 200amp alternator costs??

Electric superchargers work, Garrett has done some R+D on the subject. So far the aftermarket ones are snake oil.

Re: Finally a real electric supercharger that works. (J. Davis)
I'm here, I'm there..
What I think is cool about this one is the fact its designed for short term use.. I am thinking more of the coolness factor on factory fuel efficient cars..

Re: Finally a real electric supercharger that works. (vtec.dc2)
one thing that i see as a potential annoyance of this system is the battery aspect. the battery will not last too long IMO with such abuse. with the constant pulses of high loads i'd be surprised if it lasted a year with typical street driving habits. the battery is well over $100....not something you'd want to be paying for every year...the dynos do look nice though

OK, electric supercharger 101.
1st, your alternator is not the desired source of power for an electric supercharger. As it has been noted countless times, the drag on the engine from the alternator will offset the amount of boost supplied. Power comes from the battery.
The work that has been done is with sub-2 liter turbo cars. Said electric superchargers can increase engine output by 15% or more before, for a few seconds, before the turbo spools and takes over. That's right, an estimated 15% below 3000 rpms. I can see in the proper aftermarket application it would make a noticeable increase of more than 15%, or at higher than low rpms, but you're going to have to work at it.
JDogg strapped an electric leaf blower on a stock H22 he was dynoing a while back and got an extra 10 ft/lbs below 4000 rpms - above that it acted like a restriction. Have you ever checked an electric leaf blower's power rating? ... it's going to have to suck some pretty serious power.

some research
here's some research ive done on the "electric supercharger trend"
http://www.dieselnet.com/news/0002honeywell.html
http://www.turbodyne.com/product2.html

electrical turbocompounding.....kinda interesting
the data looks as if "electrical supercharging" helps with transient response during low engine speeds.....it helps with lag, but doesnt do much up top. i dont know if adding all the extra parts would be worth it for turbo SI (spark ignition) engines.....but it looks like it might work well with diesels.

Re: some research (javierb14)
The supercharger I posted really is a supercharger.. it has three electric motors that it uses to spin it. There is no reason why it would not work just like a belt driven super.
I just thought it was pretty neat.. Not that everyone should go out and ditch their turbo systems.
