The intercooler on this truck is massive, and located in front of the radiator. It goes all the way across the front.
Under normal conditions and eco-driving, the temperature struggles to get to the thermostat point. It has way too much air.
The boost is also at 2~4 PSI. No need for cooling the inlet air either.
I'll control the louvers for both underhood temps and coolant temps. I have to figure all that out. I'll make the linkage slotted and connect an air cylinder and springs to manifold pressure, so any time boost exceeds 15 PSI or so it will open the louvers further and over ride the main servo setting.
