<VV> Electric cooling fan results

[Mel Francis]

The main reason we are all interested in an electric cooling fan is that
it be electric, for the obvious benefit of low drag on the engine at top
speed. Also, the benefit of achieving aftercooling between runs at an
autocross, etc.
 
Since the fan tested was a bladed fan, which has now shown to be unable
to effectively pressurize a Corvair engine cooling system, how about
retaining the stock impeller fan and mounting an electric fan motor to
the top of the existing fan pulley?
 
I've found a fan motor online, made as a factory replacement for the
current GM V8 line. This motor could be mounted on a tripod bracket
above the fan pulley, with a suitable drive connection between.
 
It would appear that this setup might have the benefits of electric
cooling, with none of the low-pressure drawbacks of a bladed fan. You
wouldn't have to modify anything below your upper shroud either.
 
Since the testing group already has the test vehicles still in hand,
perhaps this mod could be readily done and a second test performed,
maybe with better results.
 
Does this look like a reasonable alternative to the testers?
