Hi John,
There has been several of these so-called Electrical
turbo/super chargers. One that was the rage a year or two ago advertised
2psi and 350 cfm for around $69.99. The thing might could have produced
2psi with no flow or 350cfm with no pressure above ambient - but not both at the
same time. Just did not have enough power.
I recently saw another one that was a bit more credible
claiming 1.7psi at 300-400 cfm with a big current drawing DC motor. They
clearly state that it was intended for only a short duration run. The
price of this one was around $350, so might be the one you are referring
to. If they can spin it to the 23,000 rpm they claim, it just might
produce some results. At least this one does appear to have a centrifugal
compressor (looks like a turbo compressor housing in the photo). Here's
the URL:
However, you will now be required to haul the weight and
complexity of a system that can apparently be used for only a few seconds.
I also considered whether it would be worth it (to me) and could not convince
myself that it would. I would certainly be interested in the results with
a rotary if you try it..

Gentlemen; After I mentioned the electric
water pump which set off the firestorm, I figured that I might as well throw
this one out. In the new JC Whitney catalog that came yesterday, there
is an electric turbo charger for on demand boost, all for $349.00. Rated
at 803 cfm, that should ram in enough air for short field take offs, while
getting away from the heat, by-pass and the continued cooling that is needed
with the exhaust turbo. Every day there are more options to experiment
with. I still have the two bushels of pistons with holes (auto related)
in them to remind me that I'm not ready to try the turbo in the
airplane. JohnD
