A turbocharger for an internal combustion engine, is provided with a turbine including a rotatable turbine shaft, a turbine wheel carried by the turbine shaft, and a drive gear carried by the turbine shaft. A first compressor includes a rotatable first compressor shaft, a first compressor wheel carried by the first compressor shaft, and a first driven gear carried by the first compressor shaft. The first driven gear is operatively engaged with and driven by the drive gear. The turbocharger has a compact arrangement, and allows for optimization of compressor wheel operating speeds, including in a turbocharger having multiple compression stages.
