Yeah,  when I get that 500 amp alternator and the 50 pound electric motor   
with enough HP to spin it. <G>

Horsepower is proportional to  torque times RPM. HP is a BIG number here  
relative to the available  electrical power in an automotive electrical 
system.

Has  anyone ever considered just driving the factory  magnesium corvair fan 
with an  electic motor?  The easiest  solution I would think would be to belt 
drive  the stock fan with an  electric motor that puts out enough power... 
electric  motors are  generally not short on torque so I wouldnt think this 
would be 
too   hard to accomplish........

comments?

HP required to drive any fan: take the ratio of the new RPM divided by  the 
original RPM--then cube it, and multiply this by the original HP.  If  this 
isn't clear, look up "Fan Laws" on Google.  Now do you understand why  the belt 
can only do a limited amount before slippage sets in?
