[DeTomaso] Flex-a-lite question

As I recall, the fan assembly I have on my Pantera is one I sourced
from a kind soul on this list ans is a Flex-a-lite. It was a pusher
assembly, that is, the fan blades were meant to push air. I however
wanted to mount it behind the radiator and pull air. I was able to
source just the fans from Summit racing so I purchased a set of pullers
and swapped them on the shroud/motors. It's documented here with some
photos:

Given that there are two distinct Flex-a-lite parts #'s I would assume
the puller and pusher have different fan blades optimized for their
respective duty, what the two units likely have in common is the
electric motors and their wiring of std color coding. As written below
the wiring instructions are unique to each part # simply indicating the
puller rotates in the opposite direction to the pusher, which if you
think about it is perfectly sane as the face of the unit is turned 180
degrees as a pusher in front of the radiator when compared to a puller
behind it.

All,
I've come to the conclusion the Hall Pantera Meriah fans are getting tired and a
re not up to the task of slow traffic cooling.
I say this because in Summer/Winter I now always see a large jump in temp when I
get into city traffic versus highway travel. 20-30 degrees jump. Wasn't always
that way.
I would rather not remount the three-pass Quella/Ron Francis radiator for sucker
fans, so I'm looking at pushers.
Felx-a-lite offers model 440 as a pusher. 2500 cfm, S-blades, etc.
But I noted the online-available PDF installation sheet groups the 440 pusher an
d the 420 puller in the same section.
It instructs the 420 puller to be wired red/red and black/black, fan to power so
urce. And to reverse the wiring to red/black and black/red for the 440 pusher mo
del. This tells me the fan blades are expected to perform whether rotating CW or
CCW. But I've always heard blades are
optimal for one direction only, and show reduced efficiency when rotating opposi
te to the intended function.
I will try to talk with a Flex-a-lite tech about this on Monday, but in the mean
time I'm asking for any of your ideas, thoughts and suggestions.
Thanks,
Larry
......and no, I don't know why my emails (at least in the archives) are now gett
ing duplicated by the List software.
