Hello, great info here, we race an FD3S RX7 here in New Zealand.
We are looking to impliment something similar to our car, based on your info.
Could you advise as to how the Gearbox & diff are cooled to prevent overheating, our car races in 8-10 lap sprint raced, produces 550 RW/HP on Hankook 280/680×18 Slicks
With the underbody there is very little airflow to the differential so we added an electric pump and setrab oil cooler and put the cooler in the airflow. On the transmission we also should have added an oil cooler similarly but we did not. We didn’t monitor our transmission temperatures but we felt a decent amount of airflow was still getting to our transmission despite the underbody covering it.
If you are doing short sprint races perhaps the first step is just to install temperature sensors in both the differential and transmission and monitor the temperatures. It would be unfortunate to add weight to a race car for short races when you don’t need to. Our car was for endurance so we felt it was really necessary to have at least the differential cooler.
