I have not seen Dave's installation so I don't know what precautions he

took, but the Setrab instructions state that the cooler  should be
isolated from all  vibration.  Mine is rated to 600 psi. If Setrab's
claims can be believed,  I don't think  dynamic pressure blew the
cooler.  I  have not worked on mounting the oil cooler yet.  But I am
going to proceed with great care, even more so after Dave's experience.
Ed knows quite a bit about isolating radiators and oil cooler from
vibration.  Maybe we can talk him into writing about this for ACRE.
Ed.  are  you listening?       Jerry

This is an interesting thread. Earl's sells oil coolers, and they had so
much trouble with people breaking them they removed all the mounting
tabs. The recomendation was to capture both sides with a "c" channel
with rubber/foam lining. I though this was overkill but did it on several
motorcycle applications. I never had a problem. These were used with
80+ psi oil and racing apps. (they saw lots of high frequency vibration
and often saw very high G impacts without problem) We all might do
well to look at the way the motorcycle manufacturers mount their
radiators and oil coolers on the motocross bikes. These operate in an
enviroment that mose people would call "abuse" to begin with!

I also felt that Mazda installed the oil coolers with such nice rubber
mounts for a reason. My cooler installation uses the original Mazda rubber
mounts and they are attached to the eng. mount tubes with rubber lined adel
clamps. The cooler does not contact anywhere any metal. I'll  take photos
when I'm done.
