I got a high engine temperature warning late in my 2nd 20 minute session at Harris Hill Raceway in San Marcos, TX. The car had 40 minutes of cooldown betwen the 1st and 2nd session. I had no temperature issue the 3rd 20 minute session after a 60 minute rest period.

Just this past Friday I did a road course class where I was the only student. I did about 66 miles that day in several back to back sessions. Here are the times that I was on track:

09:59 - 10:10 10 miles
10:21 - 10:28 6 miles
11:01 - 11:24 26 miles
11:28 - 11:33 8 miles
11:47 - 12:00 16 miles

It was 70-77F and I had no heat issues. Regardless of that, I intend to track the car in the Texas summer heat, so I've just purchased do88's complete e9x cooling kit.
