Decided to do a little more to the car over the winter.
First up is relocating the oil cooler. Stacking it in front of the radiator worked ok, but while oil temps were very good all summer at around 250, water was higher than I liked at 200-205. The oil cooler was blocking 22% of the radiator surface area. Essentially blowing hot air into the radiator behind.
So I moved it to the side so it will get dedicated airflow on the passenger side behind the stock brake duct hole. This should greatly improve water temps and also make it easier to tape over the oil inlet when it's cold.
