<VV> 90 degree cooling fans

[jvhroberts at aol.com]

 Keep in mind when comparing apples to gorillas, the Franklin was FAR lower specific output than a Corvair. In fact, most VW engines don't have the specific output of a Corvair engine. Meaning, what may be noncritical in those designs most likely is critical in our engines.

Harry,
Sounds like the way the Franklin was cooled, a large fan on the end of the  
crankshaft. The early Franklin engineers found you can get a better 
(larger-  more uniform) cooling done by "sucking" the air past something. If you 

"blow"  the air through what you want cooled it will only cool what the fan is 
pointed  at. They figured a fan sucking air over something may cool more 
with less... at  least according to an old book I have from 1920, "Everyman's 
Guide To Automobile  Care & Maintenence"...
Keep in mind they were dealing with inline six  engines (and later an 
almost 400 cubic inch V12).
Later,
Lonzo

I  remember the cooling fan (squirrel cage)
on my '72 VW bus was on the end of  the crankshaft. Very clever.

How is the blower driven on that  engine?
