Installed an extra oilcooler, between oilcontainer and heat exchanger. Parts: KYL040 cooler, AN284 AN8 oilhose, VS020 fire sleeve and 2 piece AN058 fittings. The 9 row cooler 300mm long, is very efficient, when placed in cold airflow. Some tests has been done with cooler open inside cowling, and in directed airflow. Other possibilities, to adjust cooling performance, are to slow down coolant flow through heat exchanger or change to a smaller oil cooler.
