Oil Temps.......What gives?? Options

[Fastbird]

Ok, so on the advice of people, I finally moved my oil temp sensor down to the pan and had a bung installed there. Yesterday was the first test, and it STILL was hitting 240*+ on the dang highway after 13 minutes (my highway commute) of 3000+ RPM operation, constant RPM between 3000 and 3700 RPM. It's lower, definitely, but it wasn't quite as hot as last time I drove the car with the sensor mounted in the sandwich adapter.

So what the heck gives? I watch MR2OC and I see guys talking about 200 temps during normal driving, 220 when leaning on it, maybe 240-260 ON A TRACK DAY. I NORMALLY see 240. Odd though, the temp wants to go up at idle with the sensor in the pan, I'm assuming due to lower flow at that low RPM state. I wasn't even being hard on the car yesterday, just lazily driving it around, barely getting into boost at all. And you can tell it's getting DANG hot. I popped the hood last night to clean up a couple of things when I got home from work, and that was a no-go. Too much heat.

Thoughts? Ideas?
