Plus I have a big cooler (which I need) which it cools so well along with being more oil it can't bring temps up to a certain level even with the thermostatic sandwhich plate in colder weather. Being that coolers cool so well it's not going to keep the temps at a perfect set degree even with the thermostatic sandwhich plate. Especially in colder climates. Lots of threads here on both of these issues. This is the best I can explain.

interesting...i only ask because when i was doing some research into oil coolers i remember reading about thermostatic sandwich plates. essentially, they have a thermostat, and when it reaches a certain temperature, the valve will open and allow oil to start flowing to the cooler, and when the oil is too cold, it will shut. thus eliminating the need for a plate to block off the cooler.
