A vehicle operates under various ambient conditions and various operating parameters. To compensate for the ambient condition and the operating parameters an engine, a donor intake air temperature is controlled. A donor intake air flow restriction system is used to vary the flow of the donor intake air through an air to air aftercooler. A valve is operatively moved between a closed position and an open position. A controller interprets a respective signal from a plurality of sensors to define the position of the valve.
