A compressor wheel for a turbocharger has an improved geometry that provides improved performance as compared with a comparably sized conventional compressor wheel by having the radially inward portion of the primary blades sweep upwardly into the upper region of the hub portion. The through bore and integral nut of conventional compressor wheels is eliminated and replaced with a blade extension that has an angled upper edge which extends downwardly and radially outwardly from the hub portion, effectively increasing the size of the blade, the amount of air movement and the amount of power generated, without increasing the overall cost, size or mass of the compressor wheel.
