Rather consider the PPK aux radiator kit if cooling is a concern, as water cooling will also lower oil temps. HP Autowerks also sell larger radiators. |
I suspect the OE oil cooler thermostat prevents a cooler oil temp, on a significantly colder day.
The oil temp is not only influenced by the efficiency of the oil cooler, but the temperature at which the thermostat allows the engine oil to circulate throughout the cooler.
I would imagine if you had a similar 82 degrees Celsius as the one I am running, you would see a cooler oil temps on a cold winter track day.
I would not spend the money on the PPK cooling upgrade, as you are still utilising the OE radiator that has end tanks made of plastic.
IIRC the HP Autowerks rad was removed from sale, as they had issues with leaking cores, that their supplier could not sort out.
