Abstract: An assembly includes a cast cartridge component and a curved wall where the cast cartridge includes a base plate having an opening configured for receipt of a turbine wheel, an exhaust conduit having an inlet and an outlet, a cylindrical wall, and vanes disposed between the cylindrical wall and the base plate where adjacent vanes define throats; where the curved wall includes a proximal end and a distal end, and an upper edge and a lower edge; and where joinder of the proximal end and the outlet of the exhaust conduit, joinder of the upper edge and the cylindrical wall and joinder of the lower edge and the base plate forms a volute configured to direct exhaust received via the inlet to a turbine wheel via the throats. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed.

Abstract: An assembly includes a cast cartridge component that includes a base plate having an opening configured for receipt of a turbine wheel, a cylindrical wall that comprises a shroud portion, one or more supports disposed between the cylindrical wall and the base plate, an exhaust conduit that has an inlet, an outlet and a wastegate opening positioned intermediate the inlet and the outlet, and a substantially planar surface integral to the exhaust conduit, the wastegate opening located on the planar surface; and a wastegate outlet component that includes a cylindrical portion that extends between and defines an inlet and an outlet, and a cover portion configured to cover the substantially planar surface of the cast cartridge component to form a wastegate chamber where one or more openings provide for flow of exhaust from the wastegate chamber to the cylindrical portion. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed.
