ED,
I built and electric supercharger back in 1980 that would produce about 3 lbs. of boost. It was built from a Hoover vacuum cleaner. Even then the high output motor was over a hundred bucks. I wired it direct to the alternator (back the they were external volt regs) and ran it off 110 volts. Still have it. Would make a significant difference in the performance of a GLC!

Well, I have already confessed my skepticism - however, its really hard to say.  One thing in their favor, they appear to be using a centrifugal pump with a scroll diffuser very similar to that on a turbo charger.  Meaning that if indeed they can spin it fast enough it should work.  Now one of the individuals on their  forum indicated they measured its spin at 25000 rpm.  That's a bit slow for a turbocharger but, it may indeed be enough to produce some boost.

Ed, this thread is starting to look like the electric water pump thread that can't work.  I just have a feeling that your inquisitive mind is going to go somewhere with this one.  JohnD
