Carl, what I meant is that if I could lower my operating temp so that I'm worried about TOO cool I would prefer that. If nothing else, I could manually bypass the cooler most of the time and engage it only for track days. I seriously doubt that it will be the case. Keep in mind that the car is not run in "cold" weather at all. It's a May to Oct car here in PA. No heater, defroster, it's a vert, and salt comes out in Nov and isn't really washed off the road surfaces until May. That means outside temps for when the car is running varies from around 50s at the coldest, to 100 or so.
Currently, it takes a bit during normal street driving to get the oil to 180 but then that's where it stays. That being said, I'm not usually pushing the engine on the street. I'm running Brad Penn partial synthetic 20-50.
