Abstract

A turbine wheel (10) for a turbocharger includes a hub (12) extending in an axial direction between a nose (14) and a back wall (22). The hub (12) defines an axis of rotation (28) extending in the axial direction and the back wall (22) includes a peripheral edge (20). A plurality of turbine blades (26) is coupled to the hub (12) and is disposed in a circumferential direction generally at equal intervals around the axis of rotation (28). At least one scallop (44,48) is formed in the peripheral edge (20) of the back wall (22) for balancing the turbine wheel (10). The at least one scallop (44,48) is positioned along the peripheral edge (20) such that the peripheral edge (20) is not symmetrical in the circumferential direction about the axis of rotation (28).
