Well as you can see from the above posts, we had a great track weekend! Some wins and losses on my part and I found out that some of my theories are completely wrong but nothing that can't be solved. Nothing fell off the car, nothing auto cleared but the right front needs alignment work which will be done by the shop at the track. Both gauges worked fine so that issue is solved but I now have an overheating issue.
We have a introductory program during lunch and we do lead /follow with novices to get them out and see the track. I usually tag along as it gives me time to look over things as I go out in the back and can hang back and then jump on it if I need to see something at a higher speed. First run is about 60 mph so you don't even need to brake. Coolant temp was pegged right at 170 which told me the Mishimoto thermostat works as designed. Let the car heat soak prior to the second run which they get up to around 80 mph in spots. Left pit at 220 and as we ran the temp dropped down to around 200 which should have alerted me to an issue but I am too stupid.
Later in the day we have instructor lead laps and the students get to ride in our cars. Out pounding on it, 235! Oops. I think the large trans cooler mounted to the back of the radiator is messing with the airflow through the radiator. The cooler is probably too big and simply as a heat sink it should cool the DCT. So the plan is to remove the cooler, run the car and see if the temps drop back down. The coolant gauge was bad since April so I am not sure what temps I was seeing there so it might have been an issue not seen earlier. The car did not go into limp mode as it has done before so I am assuming the limp mode was caused by DCT temps.
Previous was all done on Saturday @90 degrees.
Sunday did the same program but for the instructor laps I turn the heat on full blast. Made the ride memorable. Short shifting the the car I was able to keep the temps 220 or lower so I think I am on the right track. If removing the DCT cooler brings the temps down I will purchase a Derale cooler with a fan and mount it in the trunk venting it outside.
...to be continued.
