It can be challenging to place a rear end oil cooler in a place where youre sure there is good fresh air flow.If you can place the cooler in direct airflow, you dont need a fan, nor ducting. But in most cases you need one or the other. I prefer ducting over a fan for two reasons. A 300CFM fans flowswell 300CFMall the time. With ducting, we may see 100CFM at 30mph & 600CFM at 100mph. My experience is we get more overall airflow with good ducting. Plus, no fan means no electrical draw or problems. The main reason to run a fan is so you can cool the rear end even more on slow laps, or stopped. I find this critical with all the yellow flag laps in oval racing, but not road racing.Rear end cooling packages A & B duct fresh air to the cooler, using a NACA Duct mounted where there is airflow & 3 ducting hose to our wrap around shroud that encapsulates the cooler.Mounting the cooler in open area where the rear suspension operates is common. There is airflow going in there, but its not directed airflow. This is when you need a fan to pull that air through the cooler. Rear end cooling packages C & D utilize puller SPAL fans, so they need to be on the back side of the cooler, pulling air through the cooler.The 1.75 Tube Clamp-On Mounting Brackets in packages E & F do NOT have enough room behind them for a fan. E & F cooler packages are for mounting locations you have lots of directed airflow. 710'
