I have a F600 and would like to help improve the cooling on my car. At Road Atlanta this weekend I was seeing oil temps of 230 and water temps of 210. I have a pretty good sealed air box in front of the oil cooler and radiator that is significantly larger than the opening to slow the air down and create a higher pressure area in front. I think the flow behind the radiator can be improved upon. Currently the air has to make a 90 degree turn inside the side pods and flow into the engine bay and out the back of the car. I have a nice large flat surface on both the side and the top of the bodywork as well as a flat surface directly in front of the rear wheel to work with. What would be a good device for creating a low pressure behind the radiator to evacuate the hot air?
