I have just put in a oil cooler and filter kit.

But was thinking with everyday driving /hiway driving oil temps will be too cold??

What its normal running temp for oil in a rb25?

I was going to run a oil temp gauge and have a cover over oil cooler for everyday driving then take cover of ect on track or very hot days?

Any ideas or input?

Sorry if it's been covered I did search and google it

Get a sandwich plate with a thermostat in it. That will only open up the oil cooler circuit when the oil gets to operating temperature.

Do you do all your racing in the Antarctic?

Edit: damn you edited your post :P

mine sits around 60 deg. celcius... hotest ive seen it was 70 just the other day.. it was nearly 35deg with nearly 100% humidity in brisbane... running turbolight 4100 also..

Since you already have a sandwich plate you should get an in-line thermostat. 60deg is too cold. Your water thermostat opens (or should) at eighty something degrees.

I have one of these:

and it opens at 71deg C

Oil doesn't start to beak down until much higher temps than 100°C. No point in having a panic even if the oil is up towards 120°C, which is about the upper limit for sensible operation. Just don't flog it if it's running that hot, and if it keeps going higher than that, then you start to worry, shut it down and wait for it to cool off. 90-105°C is the sweet spot. Anything as low as 60°C is too cold to consider opening the throttle - It's not even warmed up until the oil is hotter than normal coolant temperature.

I doubt that the trip to the oil filter is cooling the oil much. And if you shift the sensor to the sandwich plate look carefully where the port is because if you connect it to the return from the oil filter it won't read any differently. Try a hood over the cooler until you can get a thermostat.

Its cooling too much.

My Greddy thermostat sammich plate opens at around 80 degrees I seem to remember. I have seen 110 degree temps on a squirt through the mountains, perhaps I need a larger cooler before I track it...

^^^^ added to my list of stuff to buy...

i still get normal oil pressure, no excess burning of oil...

so pretty much my set up is cooling the oil far too much... or is it that im not running thin enough oil?

Your oil level could go up because it never gets hot enough to boil off the fuel/water conatmination.

    • Sorry to hear your HFM BM57 was faulty,  did you contact HFM I would hope they would be at least grateful for the information if there was some sort of manufacturing fault, you would hope they would be sympathetic even if your item was 2 years old if it had never been fitted. May I ask where it leaked from ?
    • Cats are called Bella, and Donna...  Like that poisonous plant And I remember your 2 monsters, I remember making a little bit of wee when you let them out... LOL I have already installed cat doors into the laundry where their kitty litter is, and the sun room, apart from the cat doors there's not going to be any permanent mounted stuff on the interior walls (interior doors are cheap and easy to replace) I will get a outdoor cat cage thingie once I finish the landscaping out back... https://catnip.com.au/ The only off limit areas are the main bedroom and the gym room....but, currently the cats are curled up in bed, in the main bedroom with the Mrs.....LOL, the off limits for the kittens to the main bedroom lasted about 5 minutes with Jackie I currently only have 1 free standing huge cat tree multiple level scratching post thingie in the lounge room, but, I will be getting another one soon now that I'm happy with the furniture layout in the back room and have a perfect spot for it  
    • All of this is making it seem clear that running the Coppermix twin was definitely the way to go, especially in hindsight with how insane tariffs have gotten and the strength of the USD vs yen at the time.
    • That sounds like no chance of even importing one for road registering then Now I see why Duncan wants to check LHD rules for Targa...   I wonder how "bolt in" the AWD would be if you got one imported from the US and swapped it to an AUD one
    • Not to mention they drive like a bucket of bolts! yuck!
