After a full day at the track I've been debating on getting an oil cooler. I think the SP has one already but its obviously not keeping the oil cool enough under track conditions. I was seeing temps holding at about 278 after about 5-6 hard laps on a 1.2 mile course. I've done some research and it seems after oil exceeds about 250 it beings to reduce its performance, get it into the 300s and its basically acting like water. I don't see much info about charger owners getting oil coolers. Anyone have one? If so what brand, and how is it working?
