An exemplary compressor housing includes a compressor volute; concentric walls that define an annular passage and a compressor wheel shroud disposed about a central axis where a compressor wheel positioned with respect to the shroud has an intended direction of rotation about the central axis; positioned with respect to the central axis, from a lower axial position to a higher axial position, a gas inlet to the annular passage, one or more ports extending between the shroud and the annular passage and a nozzle; and a gas volute to provide, to the gas inlet to the annular passage, gas having swirl in a direction opposite the intended direction of rotation of the compressor wheel. Various other exemplary devices, systems, methods, etc., are also disclosed.
