Good write up. Thanks. And 50 degrees above ambient would be about 20 better than I get. In summer you're going to run upwards of 150 IAT.
I concur. I'm pulling air directly from behind the hot coolant entry into my radiator and get 20-30* temp rise, depending upon the time of year. I also put a small grill block right in front of that point to help drive up the temps.
