Will this fan develop the same CFM when reversed and used as a puller? On every site I've found these, they indicate to be used as pusher only, but the Derale site indicates they can be used as puller when mounting to your own shroud,which is what I have made for the 65 El Camino.

Another odd question. Just because I install two of these, the CFM remains the same...correct? Its just displaced over more area....correct? I've got a fellow telling me two of these will be good for 4300 CFM. It just didnt sound right so I waited until
I talked with my fellow CHR members before ordering.

The ones that are dual setups with shroud wont work.....I'm limited to 25" in width.


From Derale's site:

Part #16925 High Output Single Rad Fan Reversable

. Injection molded fan housing with stator flow directors
. High output 265 watt motor
. 2150 CFM
. Pusher (grill side) applications only *can be used in puller application
when custom shroud is used.

I'm wanting the most CFM I can muster with a pair of 12" puller fans bought and mounted as single units.
