Oil temperature on Track

[gugotim]

I modifed my E90 M3 with Do88 cooling package (oil, dct, power streering, radiator), and I get 100 °C oil temperature on street in noraml scenarios.

Recently I take the car to the track, in 33°C days, the engine oils get quickly to 125°C after 3 or 4 laps on 2km tracks.

Is this normal or safe? I know F8x or G8x, you only get around 110°C after heavy use on track.

Do I need to do extra things to take care of the oil temperature?

Normal and it's fine. I see 130C just from hill runs. Don't need to worry unless you see errors.

Thanks for replay.

After search from owners and posts, there comes up with a conclusion that 125℃ on tracks won't be a problem.

But still, I tend to slow down after hit this kind of temperature.

Do you experience any leaking with your DO88 power steering cooler?

Not yet after 3 track days, is it a common problem?

I went to install mine and the hose is very loose to the cooler. The hard line on the cooler seems to be a smaller diameter than stock. I had it sitting in my garage for 2 days and there is a pool of power steering fluid on the ground.

125C is def on the max upper end. This correlates to about 260F.

Bimmerworld has a nice writeup on this topic and states that oil running about 260F would be the max using a high quality oil like Red Line.
