Video of my fastest lap (I’m still pretty slow) and review of ducting and temps below:



The car was reading 100°+ on the gauge for all 3 track sessions at the event on 7/9. I think ambient was more like low 90°s.

An update on the duct I made… it was an improvement over my previous setup, because I “only” hit a max of 250-255°F in my first two sessions with similar driving on my end, despite the hotter weather. HOWEVER, I did turn traction control off for my last session (first time driving on track without it), went ~4sec faster driving more aggressively out of corners, and hit 260°. Limp mode kicked in hard. So the duct helped a bit but I still have temp issues on a hot day with multiple “push” laps in a 20min session. It’ll only get worse the faster I get.

Next step towards a solution here is adding a similar duct on the radiator/intercooler, and making a V2 of this oil cooler duct that pulls in more air. My car does NOT have the OEM radiator “side” shrouds (GTM kit deleted those) so I’m hoping that ducting the radiator will get me some big improvements in water and oil temps.

Not sure if this is related.. but my oil temp gauge is a little jumpy at higher temps. It must be going bad. I’ll get that sensor replaced and hope I miraculously have lower oil temps haha

One last thing to note.. I *think* my oil temp has been higher in general once I switched to Mobil 1 0w-40, from Redline 5w-30. I might switch back to Redline oil and see if that brings down oil temps. However, the higher temps I noticed with the Mobil 1 COULD be attributed to a bad sensor like I mentioned above.
