OK, here is another company that seems to be selling the same supercharger at the same price:
http://www.electricchargers.com/
at least they have an address (Tacoma, WA) and a phone number to call for further info.
Here are some video of people playing with them...

Here is a similar company with more info and a different product. Specifically, they have much more realistic claims, looks to be a compact size as well. I think this is the real deal.

Here is the report (from a different website) of a guy who put one of those on his NSX:

No need to add an extra battery Ed, If you are just using short bursts it will draw off your current battery.
Here is a guy who tried to build his own out of a Marine blower... did not work, tiny little motor so probably not a fair comparison:

Finally, here is a Q and A from a guy who built his own for real racing... won't apply to us, but he did it right (just does not say how)
