About the only good thing you can say about the Mazda oil cooler is
that it works.  It does not "fit"  anyplace inside most aircraft
cowls.  Even with the magic of Rhino, the oil cooler with inlet and
ducts, is as out of place as a wart on a pretty girls nose.  The
ideal oil cooler set up would be two cheek coolers  setting  in the
nose, perpendicular to the air steam.  They could outlet through
louver plates in the side.

All I have ever heard about after market oil coolers is that they
will not stand up to the pressures the rotary produces.  I have been
trying to recall the oil cooler set  up on the Star Mazda's to no
avail.  I don't think they were using the stock coolers but I may
have them confused with something else.  Does anybody know of a well
built, small oil cooler that would handle the pressure?     Lynn,
are you using the stock cooler?   Jerry

Perpendicular to  the air stream is not always or even necessarily 
the best answer. Even in a race car. Here in fact is the Star Mazda oil
cooler NOT mounted perpendicular to the air stream.
