When the engine is suddenly accelerated there will be a small time delay before the extra energy discharged into the turbine housing volute can speed up the turbine wheel.
The compression of the charge entering the cells of the impeller depends upon the centrifugal force effect which decreases with the square of the rotational speed of the impeller wheel.
Turbocharged engines produce lower cylinder volumetric efficiencies compared with the normally aspirated induction systems.
The turbocharger relies solely on extracting up to a third of the wasted energy passing out from the engine’s cylinders to impart power to the turbine wheel and compressor wheel assembly.
