Also, an external oil cooler can't hurt. For the way I beat on the car on the track, it is definitely a safety precaution.
Sounds like a good opportunity to back up what the race team claims. Replace each piece one at a time and test in between. Change the pump before you go to the track and if it still overheats you can easily replace the bottom hose and get back on the track same day to test.
