It sounds like poor air-flow or a weak WP. Thermostat good and of quality? Possible collapsing lower hose? All air out of the system? Coolant recovery system?

Like mentioned, perform a pressure test. Does it lose coolant?
I'll post a pic soon. It draws a ton of air through the radiator. The shroud completely covers rear of radiator up to fans. Thermostat is good and the lower hose is not collapsing. I shoved a thick piece of PVC in there to prevent that. I could not find a lower hose that would fit that had a spring. Thinking back, I had to use aftermarket pulleys in places. One was smaller than the original.
