Oil cooler thermostat?
#201

does anyone here have their OEM oil cooler thermostats laying around? My oil barely gets to 140-160F during street driving and only even gets to around 200F during time attack at the track. i suspect the previous owner may have bypassed or disabled the thermostats, causing overcooling on the street. i'd like to swap some OEM oil cooler tstats back in as troubleshooting.

didnt you cut one your oil temp sensor to the thread to bypass it ??? and that helped even out the oil temps???
I don't run any oil cooler thermostats and getting up to temp is no problem. But I live in South Texas. It takes about ten minutes to get oil temps above 160F in my Turbo RX8 and it rarely drops below 200F if I am driving as I normally do. That is about the same as it is in my twinscroll Turbo inline 6 335i.

One thing I’m looking for and can’t recall ever seeing is what the actual oil flow rate is to the coolers or through the engine (oil pump output)

I'm resuscitating this thread...
I've been working to maximize cooling on the track as my most recent DE saw high temps.
I believe I have the water cooling maximized without going too crazy...Griffin radiator, Davies Craig EWP, Flex-A-Lite fans, distilled water with MoCool, foam around the radiator, and an aluminum tray.
I was reading this thread and have come to understand that the biggest issue is not hitting operating temps in a street driven car, esp in colder climate.
My goal is to maximize cooling on the track, so is adding the oil cooler thermostats (from Rotary Performance which open at 165 F) the most reasonable next step to help keep the track temps down?
I don't DD this car, but I do drive it to/from the track. I live where the winters do get down to the 20-30's often, but I obviously won't be tracking in those temps or even driving it on the street.
I'd appreciate any constructive input, and YES I did use the search function already.
Thanks.

Ahh, there you are. I was hoping you’d chime in.
Well, I guess I’m wondering if I’ll see much of difference on the track with the thermostats, enough to go through the hassle of having to block off the coolers on the times I may actually drive in cooler weather.
I read a couple other threads from years ago, some which I believe you even commented, and it seemed like they were a waste of time.
Now, all these years later and with more experience from members on the forum I figured I’d see if there is more informed input available.
Thanks.

Well just like opening the radiator t-stat earlier, that’s really an influence on low load situations.
So going back to your original premise, this isn’t really doing much of anything once the engine is getting slammed under high load. The deal with blocking the bypass though guarantees that everything is going to the cooler without bypass leakage. Frankly, you should be applying the same thing to the coolant system. IMO pretty much almost everyone tracking this engine is overlooking these things. They’re falling all over themselves fawning on about foaming off the radiator and other such nonsense instead.
