Paul,
I have attached some photos of how I mounted my radiator and oil cooler in a
Cozy MKIV. My oil cooler and radiator sit end-to-end, with the oil cooler
mounted forward, to the firewall. The oil cooler just fit between the
engine mount, which was built by Conversion Concepts.
Since I'm not flying yet, I don't know how well it will cool, but I did buy
a fairly large furnace blower and I pointed the outlet of the blower toward
the air inlet, which is a modified NACA. These results showed good air flow
overall, but I was also surprised by how much of the air was going through
the oil cooler.
I had thought that I may need a deflector to get sufficient airflow to the
oil cooler, but based on my initial (and probably unscientific) test, it
appears that I may instead need to restrict flow to the oil cooler. I'm
still thinking about some sort of ground adjustable vane so I can control
the distribution of the cooling air.

Hi, fellow rotary enthusiasts....I managed to mount my radiator, and I am
now engaged in oil-cooler mounting. (Sounds like it could be "R" rated or
something). I was intending on mounting it underneath my oil pan (on a
canard pusher). Unfortunately, due to height restrictions, I cannot mount it
vertically under the oil pan. I can, however lay it face down and mount it,
then tilt it at an approximate 30 degree angle. Any idea if I might get
sufficient flow through the stock Mazda oil cooler if it is inclined
approximately 30 degrees from laying flat? If I remember correctly, Ken has
his oil cooler mounted so that the air is coming in from one end of the
cooler, running along the full length of the cooler, inside a tube. It is on
an amphibious Coot aircraft. If this won't work, I'll probably have to go
to a different size/type of oil cooler. I would prefer to use the stock
Mazda unit, because it has the thermostat built in, and should be of the
appropriate size for the 13b. Thanks for all of your input and advice.
