Improved cambered vanes are constructed for use within a vaned turbocharger and comprise an inner airfoil surface oriented adjacent a turbine wheel, and an outer airfoil surface oriented opposite the inner airfoil surface. The inner and outer airfoil surfaces define a vane airfoil thickness. A cambered vane leading edge or nose is positioned along a first inner and outer airfoil surface junction, and a vane trailing edge positioned along a second inner and outer surface junction. The vane inner and outer airfoil surfaces, in conjunction with the vane leading edge, are specifically configured to provide a vane camberline, measured between the airfoil surfaces and extending along a length of the vane, that has a gradually curved section and a substantially flat section. The vanes have characteristic camberlines that are flat for at least about the first 5 percent of the vane length, moving away from the vane leading edge, for reducing unwanted aerodynamic effects within the turbine housing, thereby increasing turbocharger and turbocharged engine operations.
