what are you track day temperatures?
with what engines and modifications?
My s50 was only getting up to 80deg on track - I do run a large oil cooler
Oil operating temp etc

Is 80 degree an ideal running temperature for when on track? I'm fitting an oil temp gauge at the moment to mine and was wondering too about temperatures.

Where is your oil temp sensor fitted?
80º sounds pretty good to me! You can also run a thinner oil with those temps and get a few HP back

Do you have a photo of it?
sorry to hyjack this but has anyone got a spare 'U'pipe same as in this picture that go's in place of the cooler lines?as iam after one....DanThe wrote:Mine is in the oil filter housing cap, so directly in the flow of oil from the pump

I can see only oil pressure as SPA and the rest are stock BMW?
Is the far away sensor the temperature one? Where is it sending its signal? If its going to the SPA gauge, have you configured the new setting for the sender in the Engineering menu?
Also those oil hose connections need looking at, I would not be surprised if they popped off under high heat and high RPM's.

hoses seem fine - did croft at the weekend with not problems!Demlotcrew wrote:I can see only oil pressure as SPA and the rest are stock BMW?

oil sensor is now in the far hole
think I best get the manual out and learn out how to configure the settings
spa gauges - seem the best on the market for ease of fitting - ie they come with all there wiring sensors etc!

I still can't see where the Spa gauge is getting its temperature reading?
I know a handful of people who have had hoses popping off with fixings like that.

80 deg C is at the very botttom of the recommended operating range for most oils...
If you're running an oil cooler, perhaps you also need an oil stat to control the flow.
My M3 runs around 100-110 deg oil temp on track and I use 15w/50 Fuchs Titan ProR.

Is that an s52 set up on yours Danthe? I haven't seen a cap with a sensor take off before. If it is then does the alternator and tensioner also have to be changed?
I'm thinking of doing some track days this year and would like the assurance of regulated and monitored oil temps. I was considering the s52 set up although I've not done much reading on it yet.

80 degrees is a wee bit low, but as Andrew rightly states, it depends on where the temp sensor is. The hottest point in the oil circuit should be the oil OUT of the engine to the cooler as this is when the oil has been bashed about by the engine bearings and whatnot.
The coolest point should be the oil into the engine after the cooler - I would aim for around 90 degrees C on the oil INTO the engine (coolest point) - it should rise about 10 - 15 degrees in the engine. Your oil cooler should be sized to be able to cool by the same amount so that oil temperature stabilisation can occur. This of course is ambient temperature related (as your oil will be cooled by an air to air oil cooler) - so 90 degrees in at an ambient of around 20 degrees is ideal.
As a general rule of thumb, mineral oils are ok up to around 130 degrees C and will work at these temps all day. Synthetics should be fine up to 150 degrees.
I would suggest checking where your sensor is and keep an eye on temperatures accordingly - a thermostat is a must!
Just as a reference point, back in my Cosworth days, we ran Sierra Cosworth oils at 150 degrees in the SUMP for durability tests of 1000 hours+
