<VV>Fanz, and how they work

[N. Joseph Potts]

If the fan can be powered with 1 horsepower rather than 15 or more, I'd say
that is a better system than the original (assuming equal or better
cooling). With advances in both motor and blade technology, I CAN imagine an
engineering option for this function that might not have been available, at
least for mass production, in 1965. However, you could also power a Corvair
with a Wankel (rotary) engine. That would save a lot of weight and space.
     Personally, I very much doubt the two 90-degree turns the belt must
take (plus twisting) to go around the corner of the engine actually consume
much power. No doubt, this can be calculated, but not by me, who has neither
the data nor knowledge of the applicable formulas.

Ron --

No disrespect to your opinions, but Tom's little set up just happens to
work. And his off-road buddies that are using this system out in the
sand say they are getting 25 more hp to the wheels (as reported by Tom).

So, maybe, just maybe, what has happened in the last 45 years, is that
some folks have engineered a better system for moving air that uses less
power than GM's Corvair design -- surely a lot is wasted with the belt
going around those two extra pulleys and changing direction twice --
with the electric fan, the alternator can be relocated axially, greatly
improving belt efficiency.

My basic thoughts on this are:

If one can cool 350 ci high perf water pumpers on a dyno with one of
these fans, why not 164 ci in a Vair?

Eddy - what happened to Eddy - had one running a couple/three years ago
that he took to convention, now Tom has one out there driving around
doing burnouts in the street in front of the hotel with a turbo on it,
and some of y'all still say it can't be done. (Yeah, he's an impetuous
young guy -- people thot Edison was a crackpot, too.)

Well, I want to tell you, it's time to sell that horse and buggy and
move into the 21st Century -- electric fan Corvairs have been done. Tom
took his wife out to dinner in the contraption Friday night (really a
very nice clean LM, a pearl goldish yellow with a white top and
accents), and then they returned in that very same car - it was still
running. Yeah, it was a bit warm when he returned, but it is a turbo
setup, he'd just been 'showing off' (above), and he shut it down without
a turbo cooling off period (remember; young, impetuous).

PS: He is not using the cheapest fan on the market - it pushes/pulls
roughly double what a stock fan will do -- remember the stock Mag fan is
a design compromise - the '60 fan, a VW/Porsche copy, is the high
efficiency design from that era, it just doesn't work well with the
Corvair layout.

PPS: John Deere has used the Corvair style belt layout on some garden
tractor/lawm mowers from the same era as Corvair, only they had a
centrifical clutch and a spring tensioner on the idler side, oem. Seems
to get my dad's lawn mowed without throwing belts - replaced the first
one in at least the last 20 years this summer.

PPPS: Tom's also got some nice big valve covers for you roller rocker
guys.
