Hey guys sorry I haven't been on the forum in a while. I'm in Puerto Rico! Anyways, oil temps were barely 220 because I was at about 6000 ft elevation in traffic climbing up Mt Charleston. Outside temps were around 95 degrees. So yes I think the f.I. oil cooler does an excellent job at keeping temps down. On top of that I was doing flybys at 9000 ft elevation as you can see in my exhaust video. Temps never passed 220 degrees. I hope this answers you're questions.
