<VV> Alternate Fans?

[hallgrenn at aol.com]

John,

All of my LMs came with one.  Even had irregular blade spacing for quieter operation.  And if they took a bit too much HP at higher than legal speeds, why I was going too fast anyway.:)

 Just a plain, really well designed fan is the answer here. Preferably without 
the mule drive...

Wouldn't a clutch fan work better ?
It would only catch when the fan speed is less than the belt speed and 
would free wheel on deceleration...

Just a thought

 Rodney....  common "clutch fans" do not work that way....  three common types


1  Cheap...centrifugal...  clutch releases at higher  rpm...  as when car is 
going 20 mph  or more....  not good for trucks / large cars....  they will allow 

overheating on hills.


2  Thermo  ... these are the normal....  only engage when the AIR going thru 
them reaches a set temp..IE  180f   Our fans PUSH COOL AIR


3  Electro-mechanical      Too big and bulky...


  Several years ago...  We tested an "Over-running clutch"  allowing the fan to 
freewheel  during downshifts /engine decel...


Sadly way too expensive... but worked fine..
