Like the title states. does any one know how many CFM the OEM 34" 05+ efans flow? I would like to know if it is more worth while to go with a higher flow aftermarket fan/shroud setup as opposed to the OEM version. If they are roughly the same the only advantage I can see with going custom would be slightly more room for the turbo system in the works.

 

do not know the specs but i see no advantage unless you need the extra room.

 

The OE fans pull a dam good amount of air when they kick to high!!! Trust me!!

 

I have LT1 fans with new motors... they hardly ever come on..

but i can override the PCM with mini switchs and they move alot of air!!

It will pull your shirt to the grill if you walk close to it..

 

yeah, the stock truck fans will too. not sure how much but i know its alot.
