I am having fits with oil temperature on my 2010 E89 6 speed N52 3.0 when I run track days. It was 91 degrees the other night at the track and I was seeing 275 degree oil temperatures on the gauge. This was after I had installed a 19 row Setrab oil cooler properly ducted and vented in the same location as the N54 oil cooler behind the lower grill under the passenger side headlight. I've never run a car that had such high oil temperatures. This is with the added quart of oil needed for the cooler and lines. The only option I see is to install a larger oil cooler behind the lower center grill. My concern there is that it will effect radiator cooling. How are others working to solve this obvious BMW design flaw?
