If you're serious about tracking the car then this problem will probably need to be addressed on a couple different fronts.
Talk to @Jake@ptf about a map specifically for road coursing the car and, if it is allowed by your sanctioning body, methanol injection. The chemical cooling effects meth injection offers is awesome.
Then look into running a better oil cooler setup than the stock unit. I know @MDORPHN has a really slick setup on his 1M and he probably is one of(if not THE) top track guys on the forums. So you may want to talk to him.

Thanks for the reply. Could you help me understand how hot cats kill power? Are they heating up the block, and therefore the oil? Would you expect power to begin fluctuating as I'm experiencing at 260* on the gauge?
