What?s the normal oil temperature for the average b230 being run very hard?

82 B21FT, i don't see over 180? F.
I saw a max around ~230 F after ten minutes of autocross (read: absolute flogging it in second gear). If I drive it hard on the street when it's 93 F ambient like it has been lately I'll touch 210 F but it drops fast. Stock heat exchanger front-mounted with -10 lines.
Looks like I need to do something about my oil cooler.
Ducting makes a HUGE difference. I played with a ton of options, finally found having a solid bellypan from the airdam to the crossmember resolved a lot of my oil cooling issues (RX7 cooler is mounted right behind the airdam opening).
One other thing I noted as well was a modification to the grille. I added an insert into the airdam opening, a section of grille I snagged from an S40. Purely for aesthetics, but it also helped oil temps. The top part of the slats is about 3/4" wide, the bottom is only 1/4", so it causes some turbulence, pulls air in better. I tried the same concept on the eggcrate, saw the e-fan runs less on the freeway.
Think I mentioned to you earlier in the year the next thing I want to play with is some sheetmetal and a brake to make ducting for the front of the car. I think my water temps creep up too quickly. I've got to really run it to build up the oil temps though.
Are you guys all running drain plug temp senders? I want to see what my oil temp does and I'm not sure where to locate the sender. Pan, before cooler, after cooler, etc?

My Lemons car [94 b230ft, aftermarket sandwich plate that I think is a 90 c tstat] has always ran 105-115 after a few hard laps and will stay there for well over an hour. Have about 3k race miles on it
I am probing it in the factory oil feed hole on the side of the block
Do you think exhaust manifold temp is affecting the sender there?
