David,
I’ve always run Griffin. On my dirt car I run the
oil cooler in the radiator because it’s less complicated and it keeps my water/
oil temps in the desired range. If I ran longer races, on hooked-up, hammer down tracks, I’d run a separate Setrab
oil-to-air cooler. With the separate oil cooler, as long as you have the airflow, the temps will be lower for both the water and the oil. The Cobra has an Earls oil cooler (identical to a Mocal). It is in the standard location and temps are never a problem.
I’m surprised that the majority takes temps after the cooler. I want to know the maximum oil temp that the engine and bearings are seeing. I will do what is necessary, with regard to cooler types, airflow, etc, to control maximum temps for water and oil. Monitoring temps after the cooler implies that you want to make sure minimum oil temp is not too low. You certainly are not concerned with or learning anything about the max temp by checking the oil at its lowest temp. That’s backwards to my thinking.
