Ok, probably last post on this thread. Again, in case it is helpful to anyone else.
I installed the Mishimoto oil cooler kit and a B&M cooler for the ATF (inline, after stock), and just took it to the track for a shake down.
I have data for 7 sessions before the cooler installs, and 3 sessions after the cooler installs. On different days, ignoring ambient temp differences.
Before the coolers, I averaged under 7 minutes of hot track time before the car started shifting at 5k rpm instead of redline. After installing the coolers, I completed the sessions shifting at redline the whole time (about 15 minutes).
Before the coolers, according to Torque, average max ATF, CVVT oil, and coolant were 257F, 281F, and 228F, respectively per session. After the coolers, average max ATF, CVVT oil, and coolant were 210, 242, and 234, respectively per session.
So, the ATF was almost 50F lower and oil was 40F lower. The coolant was 6F higher. And that is for 15 minutes of hot time, rather than 7 with reduced rev shifting the rest of the session. The coolant was a couple degrees higher even after the 7 minute mark. I'm guessing the coolant is higher because the new radiators are creating less cool air flow over the stock radiator. But, it seems to have solved my shifting problem.
