<VV> less fan crap

NO! Nobody is telling you that and frankly I don't really see how you
could conclude that.
But despite your satisfaction with your Corvair's cooling, there
remain...yes 60 years later.....two major problems with the Corvair's cooling
system. First is that the fan just consumes too darn much horsepower for the
amount of cooling it does. GM found that the fan (the best one) takes some 26
horsepower at 6000 rpm. That is a lot of power stolen from a Corvair engine
that might be producing a couple hundred HP at that speed. If the hp
consumed could somehow be reduced more power would be available to power the car.
that is the goal of most racers.
And then there is the problem with the engine. There just aren't
sufficient cooling surfaces to provide adequate cooling under certain conditions.
Chevrolet found that out when they ran their major road-trip tests during the
summer of 1966. Then Corvairs with both A/C and A.I.R overheated badly for
the 80 mph tests and overheated disastrously for the WOT testing. They had
to be shut down to prevent MELTING the engines. Sure, now I will get some
push-back that Corvairs don't overheat, but realize that these were
Chevrolet tests, not mine, and should be taken to heart. Chevrolet even knew of the
limiting cooling capability of the early Turbo power engines. Benzinger
often spoke of the driver running out of road before the engine overheated as
a prevention to disaster. And the Chev engine test engineers running the
dyno tests frequently reported that they had to let the Corvair engines cool
between max power tests just for this same reason.
And all of these were new stock engines. Just imagine the loss in cooling
when the engine has some miles on it and a few head passageways get plugged
up with dirt. Everybody is concerned with this situation.
So, face it. The stock Corvair's cooling system is adequate for most
driving conditions but it can be overheated under certain conditions easily
obtained with certain models and equipment.
