Here are some pictures of a cardboard mockup of the cowl I plan to build for my oil cooler. The 19 row Mocal oil cooler will fit flush inside the back end of the cowl. The oil fittings will protrude out the top of the cowl to allow for removal. The cowl will have both top and bottom surfaces. The cowl will be fastened to the both wing roots with Camloc fasteners.
The front opening of the cowl is right above the leading edge of the wing to allow it to collect high pressure air. The opening will be 2" tall by 13" wide.
This setup for the cowl and oil cooler does not leave much room for the thermostat which I was planning to install. The oil line routing without the thermostat would be straight forward. I will do some more research to see if running without it would be recommended.
