Even the thermostatic plates allow for a small amount of oil to flow to the cooler at all times to prevent air lock. So what that means is even though its not full open below 185F the cooler is still getting oil circulating through. I tried blocking mine off but then of course coolant temps started to run higher. So I just disconnected it. I even replaced the Mocal plate as a test. Same story.
This weekend we finished our track video with the S2000 and honestly we just parked the FRS after 4 sessions. On 10w30 I got 9 flat out laps before temps hit 245F and oil pressure hit 45PSI at 7000RPMS. Just did two cool down laps to let oil temps recover, then got another 4 laps before it hit 245 again. Ambient temps were around 65F.
Now the answer I keep getting told to run a bigger cooler.
Well I already have issues on the street with over cooling as it is.
Its not a race car I get it. But there is no good in between.
High oil pressure can be just as bad as low. And I hate seeing 85PSI at 2000RPM for half my commute to work on 10w30.
So its just another thing to deal with if I want to track this car. Change oil at track to 30 or 40wt, and switch back to 0w20 for street duty.
Remove oil cooler during winter, put it back on in spring.

What about one of those Laminova water/oil cooler setups? How effective would that be warming in the cold and cooling in the hot?
