[DeTomaso] Flex-a-lite question

[Julian Kift]

In all fairness I think it was  sustained 150 mph before he hit cooling issues!When I mounted my Flex-a-lite sucker fans I fabricated brackets and stand offs to obtain the correct 3/4 inch (?) clearance for the fans from the radiator core. The standard shroud and rubber gasket put them almost on the   radiator which reduces efficiency.Julian
> >>>My most strident objection is to mounting a shroud-system fan in a 
pusher application at any time.   It will block a substantial percentage of the 
surface area of the radiator from seeing airflow.   The net result is like 
fitting a radiator that is 20-30% smaller than what you have now.
 
That's cubic dumbness.
 
If you really want one of these deals, install it in a sucker application.  
 Those work well except they restrict airflow at much higher speeds.   
Johnny Woods saw overheating in his car with that kind of setup at triple-digit 
speeds because air would stagnate on the back side of the radiator and 
couldn't escape.   In typical Johnny Woods fashion, he fabricated a series of 
one-way flaps that would open up when pressure dictated, yet suck closed when 
the fans were providing vacuum, and that cured the problem.
 
Seriously though--if you have Meriah fans, you have some of the best fans 
you can buy.   Look elsewhere for your problem first.
