um, i was checking out pictures of zeff789's and it was suprisingly small. the whole kit doesnt weight much at all.... im going to try and ask him the shipping weird of the package (might not be TOTALLY accurate, but i try)

973 amps / 3 = 324 amps per motor !!!
2/0 wire is recomended
man if that shorts out to chassis ground....
I mean if you've ever worked with that kind of power you would understand how dangerous this kit can be if installed wrong or you get into an accident or something. The arc would be like the equivilant of a small bomb going off in your car, not to mention the extra batteries would probally burst.
I honestly think for all the trouble its easier and safer to get a regular supercharger this seems like more work plus you only get 10~20 seconds of boost per charge. Not to mention its only the blower for 2 grand plus you need all the extra stuff.
Granted its a neat idea but as far as using electric motors for boost in cars the physics arent in its favor.

Very well put in the last statement you made. Stephen, it is nice to actually have a member who can calculate the equations of the energy and look at things from a purely functional standpoint. People need to not let there previous knowledge or in most cases ignorance influence opinions on things like this new invention.
Others have stated weight issues, when you will only be adding roughly 75lbs to the vehicle. The extra batteries are ~15lbs x 2 so 30lbs add another ~30 for the blower and starter motors and maybe 15lbs for wiring and brackets. The batteries would be isolated from the main electrical system but allowing a charge back system to be incorporated and would most likely need to be mounted in the front of the car for current draw and shorter wire reasons.
When people start understanding this system the intrest will grow and soon the fact that you can put this on just about any vehicle with the right modifications will be a major plus. I would probably not buy it now myself but if it were available in the future for a complete system around $1500 that would be a steal. Max boost at any rpm, wot instant boost, hard hitting like N20 and without the bottle and refills. This is for real and you heard it here like 3 months before its official release.

The important thing though, is that there is nothing theoretically unsound in using an electric motor to power a blower, there are only practical issues in making a useable system. And there are some very attractive features about an electric supercharger from a control aspect.
Unfortunately, the $50 ebay electric superchargers have prejudiced people against the concept.
