Eaton has posted up a video on Youtube demonstrating how the bypass valve works for low throttle cruising conditions, and the laminova cooling cores built into the manifold.
Under full throttle, the bypass valve will close, giving full power, and under light throttle the valve will open as boost doesnt need to be made for light throttle/cruising.
