A turbocharger system for an internal combustion engine is provided with at least one rotatable shaft and a multi-stage compressor. The multi-stage compressor includes a first compressor wheel carried by a corresponding shaft, an axially extending first inlet associated with the first compressor wheel, a radially extending first outlet associated with the first compressor wheel, a second compressor wheel carried by a corresponding shaft, an axially extending second inlet associated with the second compressor wheel, and a radially extending second outlet associated with the second compressor wheel. An interstage duct fluidly interconnects in series the first outlet associated with the first compressor wheel with the second inlet associated with the second compressor wheel. At least one bypass duct is provided, with each bypass duct fluidly interconnecting the first outlet with the first inlet; the first outlet with an ambient environment; and/or the second outlet with the first outlet. At least one valve is provided, each valve being positioned within a corresponding bypass duct. A controller is coupled with each valve and selectively actuates each valve.
