Been through 3 plates now and talked to Mocal directly doing testing.

If you are on the track and depending on the track and oil used it would be easy to hit 245F in a 30 minute session if you are flat out.
Again depends on the fuel, our tracks all run Sunoco race fuels. At autobahn there are race teams onsite who put warnings out for street cars to only use the 100+ octane without cats. They have had plenty of people with issues. It started with guys loosing cats on a Ferrari or GT3 so they warn everyone.
You don't need race fuel on a tune designed for 91/92 octane if the tune is sound, its just insurance. You should be able to know this logging right away on street and first track session.

Maybe I should disconnect the cooler for the winter? I wont be going to the track between October and May anyways and I should not need the oil cooler for street driving.
We can get 93 octane here, but not everywhere. Most of the time I am stuck filling up with 91.
What problem did you have in the winter?
