Hi: With my system, which is a front radiator AWIC driven by a 12V circulating pump to the engine compartment I see about ambient temp +10F for the AIR temp to the engine after the intercooler. What I don't know is if the radiator in front is returning the water back to ambient, or if the extra load from the oil cooler would drive the need for a bigger radiator in the front. I have a dry sump whose discharge line goes through an air to oil SETRAB cooler that is ducted with two ducts to the side scoops, before sending the oil to the Spintric and reservoir. There is fan assist controlled by thermostat as well on the air to oil cooler. Where I was running my car, I would see 105F days and 60F days. I typically ran 20 minute sessions. My biggest heat challenge was with the 5MT. On the short track in NM at 80-85F outside temp, I saw 102 after the AWIC, engine coolant temps of 190. Oil temps of 205-215 and 225F on the 5MT using an infrared.
