: and what the 'variable nozzle' feature is: the compresser wheel is actually 'variable' in that as the engine speed increases, so does the angle of the vanes on the compressor wheel: adjusting to all engine speeds.
Nope.
The compressor wheels spins at 100,000+ rpm. Rest assured that the vanes are stationary on it. What does change is the angle of the vanes surrounding the compressor in the compressor housing. This changes the angle which the air contacts the compressor wheel.
