[DeTomaso] Flex-a-lite question

[jderyke at aol.com]

FWIW Larry, Flexilite shrouded sucker fans can be mounted tothe back of a straight-up-mounted Pantera rad. There are several in Nor-Cal rigged this way. By adding a pair of simple  2-1/2" long straps to the stock upper mounts, you then have a lay-down rad, which makes water and electrical hookups easier and less damaging to knuckles. No other advantage to a lay-down rad. The only disadvantage is, longer than stock rad hose sections are needed to hook up. Both straight up & lay down have room ahead of the assembly for a front-mount A/C core.  
Hi-output DC electrical motors sometimes need brushes replaced and an occasional shot of oil in the front & rear bearings.bushings. If done regularly,  they will normally outlive us!

   All,
   I've come to the conclusion the Hall Pantera Meriah fans are getting
   tired and are 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 and the 420 puller in the same section.
   It instructs the 420 puller to be wired red/red and black/black, fan to
   power source. And to reverse the wiring to red/black and black/red for
   the 440 pusher model. 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 opposite to the intended function.
   I will try to talk with a Flex-a-lite tech about this on Monday, but in
   the meantime 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 getting duplicated by the List software.
