One oil cooler is not enough

SunsetZ

I installed the largest Setrab cooler available for the Z and on the third 25 min session at PBIR it hit temps high enough to limit rpm. The 13 and 14 model year cars have a collar between the engine and oil filter that uses engine coolant to help "cool" the oil. I have a feeling this is actually heating the oil instead when a separate cooler is installed. I took it off to see if I could just put a return on it and not use that coolant thing, but there needs to be a new threaded fitting made to be able to connect the Setrab directly to the engine. Anyone know if these are available?

I turned the heater to full blast and that helped get some heat off the engine, but in Florida even with the windows down, that is not comfortable. Any ideas on how to have the heat set on max, and get that air directed outside the car instead?
