how does the 2012 factory oil cooler stand up to track/auto x

ban25

With a 34-row cooler in my '09, I typically peak out at 240F on the track, including at ACS. Before that, I was hitting 300F and experiencing severe limp mode. Obviously the 2012+ model years have improved cooling, but I would still be concerned about hitting 260F+ because you are likely to get some reduction in performance even if it's not full on limp mode.

Whats times were you running at ACS. I had a base stock 09 7AT and never hit limp mode. I was kissing the 265-270 every now and then but never really got close the 280. i ran 2:10-2:12 times

I run 2:08 at ACS. Even at 260, the engine's going to be slower...it seems to me that you start losing performance gradually at 240F and it gets really severe, to the point of restricting RPMs, at 260-280.

I was running 2:05-6 with passenger on OEM tire (stock everything) , but nowhere close to that record 2:01 posted T_T. Engine is significantly less peppy and just doesn't rev when it gets >260.

From what it looks like on this forum, the oil cooler definitely does something, so if you were fine without it, you should be even better with it (unless you have more mods on this one?)

And hmmm, next time I should just not engine brake as much, maybe just brake and downshift at last second. But my brakes also overheat after 3 laps T_T
