Oiling issue during autocross

The problem is that the oil temperature gets too high and causes a significant drop in oil pressure.

For my car (Base 986, running Motul 300v 10W40, EBS oil baffle, Boxster S Oil cooler) the ticking happens when oil temperature hits 230F.
At this temperature or above, the oil pressure @ idle drops bellow 10psi and the tick becomes audible.
Under these circumstances - coming back to the paddock or after finishing an autocross run - I keep the revs above idle where oil pressure is 15psi or above (no ticking)
Of course, this is no real solution.

At this time, I'm hesitant to install a 3rd radiator. I wonder if using 15W50 would help minimize the oil pressure drop when the oil temp hits 230-240F

I've added a temp gauge and oil pressure gauge -- I'll have to keep an eye on
those my next track day.

contemplating adding a fan and external oil cooler.

As I have the S -- I already have 3 coolant radiators.
