A compressor assembly (404) includes a compressor housing (412) having a main inlet bore (424) and a secondary inlet passage (422) that has an increasing flow cross-sectional area. The secondary inlet passage (422) is positioned in the compressor housing (412) and around the main inlet bore (424). A secondary inlet slot (426) and an outlet slot (420) fluidly connect the secondary inlet passage (422) with the main inlet bore (424). A compressor wheel (418) is in the compressor housing (412) and has a stepped portion (518) formed by at least one plurality of vanes (506). The stepped portion (518) is located adjacent to the outlet slot (420) of the housing (412).
