Abstract: An exemplary compressor wheel includes a proximate end, a distal end, an axis of rotation, a z-plane positioned between the proximate end and the distal end and a proximate end extension wherein the extension includes one or more pilot diameters and an engagement mechanism for engagement with an operational shaft of a turbocharger.

Abstract: Methods, devices, and/or systems for controlling intake to and/or exhaust from an internal combustion engine. An exemplary method for controlling intake charge pressure to an internal combustion engine includes determining one or more control parameters based at least partially on an intake charge target pressure; and outputting the one or more control parameters to control an electric motor operatively coupled to a compressor capable of boosting intake charge pressure and to control a variable geometry actuator capable of adjusting exhaust flow to a turbine.
