First problem with flipping the inlet was the bypass actuator had to be flipped to the other side. This entailed removing the bypass blade/shaft and the actuator itself.


The actuator is vacuum controlled. With engine vacuum the valve is opened allowing air to bypass the rotor lobes thus reducing parasitic loss and increasing efficiency.
When there is no vacuum, and the blower starts to go into boost, the actuator forces the valve shut.

The actuator is calibrated by Eaton (Magnuson in this case) so it must be installed the same way to keep it accurate.
