My pleasure. It is uncommon for anyone to do this level of research and data logging, much less share the data. Even the company I used to work for didn't bother, but boy did they sell a lot of transmission coolers. Personally, I'd rather know exactly what is going on by doing the testing and ensuring that target performance is actually met. Who would have known that the airflow modifications we did made such a significant difference unless we tried and verified the modifications actually worked.
The track testing I did was not a full road course and as such, is more comparable to an auto-X course. The difference between the track I went to and an auto-X course, however, is that time between runs is much shorter. In the auto-X days that I have done, it was a good solid 30 minutes between 50 second runs due to the sheer number of people at the event.
The nice thing about the airflow mods is that when you are on a road course, you are moving much quicker and you are getting better air flow through the cooler. The other nice thing about an HPDE event is the cool down lap. With this setup, you simply won't have temperature issues because you'll actually be getting the temps back down before you even pull into the pits (provided you actually take it easy on your cool down lap). In addition, the HPDE's that I have attended have about an hour to 1.5 hour break between 20 minute sessions. Compare that to the 9 - 10 minute break we had at Adams and the transmission will have plenty of opportunity to cool down between sessions.
