1. A method comprising: rotating a compressor wheel about an axis in a compressor housing that comprises an ascending annular passage that surrounds a ported shroud wherein the rotating draws air to an inducer portion of the compressor wheel; swirling exhaust gas received from an internal combustion engine in a direction opposite the direction of rotation of the compressor wheel; introducing the swirling exhaust gas via a gas inlet to the ascending annular passage; forcing air radially outward through one or more ports in the ported shroud to the ascending annular passage wherein the one or more ports are located axially above the gas inlet to the ascending annular passage; in the ascending annular passage, mixing the swirling exhaust gas with the forced air; and introducing the mixed air and exhaust gas to the compressor wheel via a nozzle.
