Agree on the oil temp. I was probably driving 6/10 or 7/10. I can tape off one or both of the intakes that go to the rear-mounted cooler on the cool days. The test this time out was if I could get cool enough. The time before, the spintric was before the cooler and I think was bypassing most of the oil back to the tank. Now all the oil/air from the scavenge pumps go to the heat exchanger first. The Setrab rep told me the cooler would be fine with air/oil mixed. From there it goes to the spintric back to the tank. It will be interesting to see what happens when the air is 105....If I can succeed there, I will no longer need the oil coolers up front and their associated lines. That would be nice. For now, they are clean, empty and capped off awaiting warmer weather.

I wonder how "linear" oil temp will be with ambient temperature? All else being equal will a 50F increase in ambient temperature translate into a 50F increase in oil temp? Time will tell.
