I have a RV-6A that has an 8 Row Stewart Warner Oil Cooler mounted on the firewall behind the #3 cylinder. I use a 3" scat tube to run air to the oil cooler. Every summer I have issues with oil cooling and am looking for a good solution, especially since I live in Las Vegas!
I use a plenum for cylinder cooling so mounting behind the #4 cylinder is not an option.
My question is: does anyone have experience with using a NACA duct to route air from the side of the cowling to the oil cooler. Or using a duct/vent on the bottom of the cowl to help draw air more efficiently. Looking for ideas and pitfalls to watch out for. Thanks.
