Mike, are you using vibration isolators to mount your oil cooler?   Jerry

Jerry,

  My oil cooler will be mounted in a "tray" lined with 1/4" neoprene. This
is the stuff sold at hardware stores for use as door insulation. The guys
where I bought my Setrab recommended this. Their customers using Setrab
coolers in Baja racers use this mounting scheme.

  The tray will in turn be mounted to the airframe or engine mount. Still
not certain of the details. I'm now working on my third iteration of
building an oil cooler mount and ducting. The first 2 iterations I wrote
off when it became clear that the chosen locations/ducts would be
hopelessly inadequate at providing sufficient airflow.

  Charlie and Paul, thanks for the follow up info on Positech. I wasnt
aware that they had changed designs and expanded their line. I'll take a
look. I'm confident that the Setrab I have is safe, but may eventually need
a cooler with slightly more capacity.
