Yeah, that's a good idea, better if you can log it and see what it does during track events. Oil pressure can be an issue with these cars, but it's not temperature-related but rather oil-feed related, RTV blockage, drops during cornering (more an issue with '22+).

275F indicated is reportedly 255F at the sump. This is just no big deal for any decent 30-weight synthetic, and if you want higher pressure than what that gives just run 40-weight. Honestly at 235F indicated I'd probably just run 0W20 street or track all year. These cars have had engine failures with and without oil coolers. Some are so fixated on it that one guy with a cooler and 235F oil temps had a failure, and was desperate to get oil temp lower still for the rebuild! It wasn't the oil being too hot that caused failure... Last edited by ZDan; 11-28-2023 at 08:17 AM. |

Have you seen this thread ? I find more and more people trying to keep the oil cool. Running high oil temps might not been an issue but I still can't wrap my head around wanting to run higher oil temps just cause. https://www.ft86club.com/forums/showthread.php?t=154233

Also, my grandkids are still at the age where they're salivating over the car. Maybe it'll be an heirloom.

What I don't get is the fetishistic obsession over lowering oil temps that are perfectly reasonable. |

I think it boils down to "There's more than one way to skin a cat"
There are many people doing different things and all having good outcomes. |

Kinda reminds me of my 240Z days, one guy in our local Z club would always go on about the 4-row aluminum radiator he put in his stockish power 240Z and how it never overheated. Meanwhile I had a stock 260Z radiator in mine and it never overheated either, on the street in traffic or on the track, while running a high-compression big-cam 3x2 45mm carbed 255rwhp 3.1 liter monster. I mean, yeah, he had a ton more cooling capacity than me, he just had absolutely no need for it! Last edited by ZDan; 11-28-2023 at 10:12 PM. |

Oil gets to a lot of places in an engine that cooling water can`t. So it picks up heat from some very hot areas. It gets a lot of heat from areas in the engine not in oil pressure. Oil is not the best for exchanging heat, but it does and it reaches far more places than coolant water. That`s why it gets so hot and not forgetting its primary purpose of lubrication.
