Abstract

A turbocharger is provided having a turbine wheel (4, 4') with a plurality of extended tips (400, 400'); and a variable turbine geometry assembly in fluid communication with the turbine wheel and having a nozzle ring (6) with a plurality of vanes (7) movably attached thereto. One or more of the extended tips are non-parallel with an edge of one or more of the plurality of vanes. The incidence angle can vary and can be from 1 to 60 degrees. The extended tips can extend into an inlet of the vane space housing the vanes.
