Oil Cooler, Oil Temps

[mr turbo]

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.

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..

Do you do all your racing in the Antarctic?

nope but i was just reading how people have oil temps up around 100 degrees and i was like WTF?

[Piggaz]

What's wrong with 100 degrees?

[defari]

40 odd degrees hotter than mine? makes me think my car has a problem...

[N1GTR]

Mines around 80 normally, but give it stick and the temp goes up of course. Thats HKS cooler kit with thermostat.

[rob82]

Yeah you need to be least be close to boiling temp to get rid of any moisture in the oil. I would be concerned if it was over 105.

i use this

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

^^ cheers - sorry to the OP for hijacking the thread

i read somewhere on here that wot water temp should be simliar to wot oil temp?

[GTSBoy]

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.

Urban myth on oil temperature , it run fine at 90-100C . 60C is really low and you will be losing to cool oil drag . Also as was mentioned this is not hot enough to boil off condensation or combustion products that get past the piston rings .

cheers for the info... could it be that the temp sensor might be in the wrong place? mine is on the relocated oil filter bracket.. should it be closer to the block? i.e the sandwich plate which connects to the block?

[KiwiRS4T]

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.

^^^^ 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?

[scotty nm35]

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...

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