Certainly some fascinating claims, Dave.
1 psi would appear in the feasible category on the one. The $299.
price for the other which from the photo appears not to be a turbo compressor
scroll, but black ABS plastic which is different from the Thorton photo of a
turbo compressor scroll for $99.00.
The Thomas Knight electric supercharger appears the most
credible by far. He is using 3 starter motors to drive a positive
displacement compressor to get 3-6 psi boost using 700 amps at 12 volts - It
appears he went to three 12 volt batteries in series to get the voltage higher
and lower current. So that installation has got to weigh a ton counting
the three batteries.
Still looks like the mechanical driven supercharger or
exhaust drive turbocharger are still the most credible means of forced
induction. I had hopes for the Aeorchallenger Turbo that came out
requiring no lubrication lines back a few years ago (had its own self contained
lubrication), but they never had one for the rotary and it appears they have
vanished from the scene.
Well, fun to think about a $99 supercharger that would
produce 3-6 psi of boost - but, I don't see it happening. So guess got to
wait for the 16B as Dave suggested.

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)
