Just as a comparison I finally got around to installing my Oil and water temp gauges. Well it does seem the HR is a cooler motor.
It was 102 degree's out, and the car's oil temp was reading a steady 190 degree's. I got it as high as 205 when I shifted to 4th at 70 and left it there for a little bit. Water stayed around 180. Will have to see what it does on the track now.
