this is the root of LLY cooling system problems. This is with a light load, on a normal Phoenix afternoon. I have had this number as high as 245.
At 245, and 20 psi of boost, at 5000 ft elevation the CAC offloads an additional 154,000 BTU/hr into the radiator. This is as much heat as is required to heat about 5 homes in North Dakota. Not to be too dramatic, the radiator is under attack.
