“You can see that while inlet air temperatures were within a few degrees of each other, the oil temps on the OE cooler just climb and climb, until about 260F where I called it quits and did cool-down lap. With the CSF cooler in place, despite almost identical ambient & track temps, engine oil temps seemed to level off right around the 235F mark.”
