Typical Oil temps you guys see?

Typical Oil temps you guys see?
I maybe just getting a bit worried over it...
I run 9 psi on my FM GT2560 on a AEM FIC piggyback on my 03 with the 6 speed
Big 55mm rad, coolant reroute, and I normally run 5W40 Liqui-moly oil (as i can get it decently cheap)
At highway cruise, I am seeing oil temps rising to about 240F and even up to 245 after about 30 minutes on the highway, and not on a very hot day. Normally it stays around there after that but I haven't taken the car on a far enough drive to find out if it'd get past 250 after about 1 hr on the highway.
Just want to know, is this normal to see? Perhaps I got too used to seeing a relaxed 210 when i was in N/A form.
Has anyone done any scientific testing on the benefits of an oil cooler?
Thanks

My oil sits at 185 degrees during street driving. On long road trips on the highway it will sit at 195. On the track it was consistently at 215-220.
I would be worried about 240* oil temps during normal use. That's not cool (pun intended).
I will let wiser people chime in about what they think may be the issue or what to do about it, but you shouldn't be seeing those temps during light use.

Oil temp will depend on where you take your sample from. My probe is in a filter plate, and I will see oil temp ~30° over coolant at high speed cruise.
A sensor in the sump should see (significantly) lower temps.

My sensor is in the pan.
Before the oil cooler (not even the stock one) 200* cruise, 240* on 100mph pulls.
Now I have a crappy Canton oil cooler that keeps everything at 180* unless I'm on the track...then its 260*. RX7 cooler is going in soon.

Tap sump = oil drain plug... you're reading the oil temp in the sump both times (which isn't really a bad thing on a wet sump car). Best place is somewhere after the cooler and before the pump inlet, you don't really care how hot the oil is coming out of the engine, you want to know if the cooler is doing its job and the engine is getting cool oil at the inlet.

Exactly. You don't need to see it inside the turbo either. Generally you want to see what comes out of the engine - THAT will tell you if your cooling is OK.
Your cooler might be able to bring it down to 250F, but what does that tell you? It might be going in at 300F? If it goes in at 260F you know you're on the edge of OK.

My RX7 cooler sat in the garage for about 8-months now...it may be ready to go in the car now. I don't know if any more time on the shelf will make it more efficient.

I made the same numbers when I had no oil cooler at all. If you don't duct it, it won't work...it also needs to be a decent cooler too, not some crappy JC Whitney trans cooler POS piece of ******ry.
