An exemplary compressor wheel housing for a turbocharger compressor wheel includes a substantially cylindrical shroud surface definable with respect to a radial dimension and an axial dimension along a rotational axis of a compressor wheel with an origin coincident with a z-plane of the compressor wheel wherein the axial position of the shroud surface decreases with increasing radial position to a compressor wheel blade outer edge radius and a diffuser surface extending radially outward and axially downward from the cylindrical shroud surface wherein the diffuser surface includes a minimum diffuser surface axial position at a radial position less than about 1.25 times the compressor wheel blade outer edge radius and wherein the diffuser surface includes a greater axial position at a radial position beyond that corresponding to the minimum axial position. Various other exemplary methods, devices, systems, etc., are also disclosed. |
