A centrifugal compressor for a turbocharger includes an inlet-adjustment mechanism operable to move between an open position and a closed position. The inlet-adjustment mechanism includes a plurality of blades disposed about the compressor air inlet and located between an upstream wall surface and a downstream wall surface of an annular space within the air inlet wall. The blades are pivotable about respective pivot points such that the blades extend radially inward from the annular space into the air inlet when the blades are in the closed position so as to form an orifice of reduced diameter relative to a nominal diameter of the inlet. Aerodynamic pressure balancing across the blades is achieved by spacing features that space a majority of the upstream surface of each blade from the opposing upstream wall surface.
