Just realized you were saying it shut down at 220*F.

How much fuel did you have in the tank? If you are not on a full tank the car has issues with fuel running away from the pickup and starving the engine.

I think the issue is anything but the oil cooler not doing it's job. I've never heard of anyone needing 2 days after a hard fuel starve before they could restart the car either tho. My best guess is it's neither of the above and just some random sh!t wrong with the car. Not very helpful I know but if the car isn't overheating and isn't throwing a diagnostic code, and now runs fine, it's going to be a nightmare to figure out.

That's true.

So that car is running like nothing ever happened?

What was the CEL code?

It didn't throw any code.

That is awesome. Good luck finding the cause of the shutdown..............

LOL that this thread just came back from the dead. I'll answer my own question even though it's obvious. Yes, a 25 row cooler solves the overheat problems on track in 95% of situations.

As for the reviving post, that's not your oil cooler or limp mode. That's an engine fault that apparently isn't monitored by the engine diagnostic system.

I got up to 265 ish really quick when I drove on GMR for only 5-10 minutes. Didn't even get 1/4th the way of the route I was planning on taking. After an oil cooler it never went above 240 and I drove the whole thing this time. I also purposely drove it harder/reved more cause I wanted to make sure the oil cooler helped keep things cool like it was supposed to.

In summer at between 97-99 degree ambient temperature at Sears Point I slowly got my oil temp up to 260 with high heavy revving and no limp mode and no problem.

Gas starvation sucks with or without an oil cooler.

I hit 260 over the summer at 105 degrees but I didn't hit limp mode. What pissed me off is how fast I got to 260. 2 more months and I'm installing the cooler for the spring.

At race pace, up to 25 minute sessions, 100f ambient, I have not hit limp mode once. I see temps ~280f max.
