I have been running two mazda oil coolers in parallel and the oil and
water temp has been running at 200 on both I removed the mazda
coolers and installed a 80000 btu fluidine cooler and the water temp
went to 240 and the oil went to 250 at that point I added one mazda
cooler back on and both water and oil temp went to 225 so I went back
to the mazda coolers I guess if it works don't fix it.

Ken,

  A little clarification please. I assume this means you've been running
the  2 stock Mazda air-oil coolers to cool the oil in addition to a coolant
radiator? How large is the radiator?

  I also assume that the Fluidyne unit you tried was a water-oil cooler?
Did you up the size of the radiator when you made this change?

  Fred Moreno estimated that we would need a 100,000 BTU water-oil cooler
to do the job for a 180HP. So perhaps not too surprising that your
experiment with the 80,000 BTU Fluidyne cooler didnt work. Particularly if
you didnt increase your radiator size by 25 - 35%.
