There is a flat fan kit, produced many years ago - for racing use. It  
involved a ducted shroud on top of the motor and a correctly pitched flat fan.  The 
one used was from a water cooled car  - an Austin America. The fan was  
pitched this way because of the transverse nature of the Austin. Anyway, several  
people used it for an assist fan for road racing and autocross. Of course the  
motors were cleaned up and tightly shrouded for this use. All in all it was  
still marginal. If the cars were not going at a reasonable rate on course, they  
would heat up. I believe there was a ram-air component to the overall 
cooling.  Nothing special, just the regular Corvair effect. Sitting still on grid, 
not  enough helping flow would cause heating up. - Seth  Emerson
