Okay, I know I'll get clobbered by BOb on this idea but here's
at it.
There was a guy in California who spent a lot of time tinkering with
propeller mechanics. Now this was done to figure out how to wring
out more energy from the wind for those electrical wind generators
who's designers seem to always copy the airplane propeller to catch the
energy from the wind.
Now I read this in Popular Science and was fascinated with his findings.
So much so that I wondered why the reverse couldn't happen.
Namely, take his redesigned wind machine propeller and use it on
an aircraft. The reason? He managed to prove his design could get
45% efficiency from the wind rather than the 12% from the airplane
propeller. Anyway, his working model impressed Popular Science Mag
enough to publish his results for wind generators.
So . . this propeller could make a 50 HP VW motor very . . . ?

*p.s. those % are from memory.

Yep. We have a lot of VW powered airplanes around here.
Heck, I've had two myself, and a new one about to hatch.

A home brew VW engine making 50 HP or so is one thing.

A home brew turbo is another breed of cat completely.

I'll happily let those with less brain power have at it.o
