<VV> Electric cooling fan results

[corvair at mts.net]

I bet Tom's race car was running rich enough that at those speeds he saw significant cooling through the fuel. In the case of propane, you'd think ingesting ice-cold propane (due to expansion from the pressurized storage tank) would freeze that engine right down.

Gee Tony, maybe we should ask Tom Keosababian just what sort of FAN he  used 
for cooling during his 157 mph (on gasoline) and 170 mph (on propane) runs  at 
Bonneville.  According to Car Life magazine, he also drove the gasoline  
powered car to work which would imply it stayed cool enough at more "normal"  
speeds.  He must have been putting out well over 300 HP for these  runs.  I'd say 
he had a LOT more waste heat to get rid of than the 95 hp  car driven at 40 to 
60 mph!!

That mag  fan is a simple casting that has NO attention paid to 
aerodynamics or  efficient air flow.  The only thing it does is beat 
out a more  efficient fan in manufacturing costs and less weight, 
which means belts  will stay on better, both factors more important to 
GM...  efficient  cooling is a lesser matter when money is concerned, 
when the mag fan would  be "good enough".

Well...  we see today that in certain  applications it's NOT enough.


I would really like to see some  modern test specs on Corvair cooling 
fans.   I mean *Modern*  test specs and not the specs that GM drifted 
down through  channels.
