Turbocharger compressor wheel must be constructed of cast or billet aluminum.

A small hose can connect from the turbocharger compressor outlet, charge pipes, or intake manifold to the nipple on the wastegate actuator.

The turbocharger compressor housing features a built-in bypass valve, and the turbo housing is cast into the exhaust manifold with a loop-around flow pattern.

Actual characteristic curveWhitfield, A. and Wallace, F.J., 'Performance prediction for automotive turbocharger compressors', Proc.

If no valve were employed and both compressors were merely routed directly to the intake manifold, the supercharger would blow backwards through the turbocharger compressor rather than pressurize the intake manifold, as that would be the path of least resistance.

The turbocharger compressor housing had four vanes made from heat resistant Inconel alloy surrounding the turbine wheel on the air intake side that would fluctuate based on engine load and transmission gearing above 2,000 rpm to allow for increased airflow into the engine as needed.
