A turbo system often requires a specially designed exhaust manifold to handle exhaust heat and pressure, and to properly deliver exhaust gas to the turbo unit.
2Turbine section Engine exhaust flows through the turbine section of the turbo.
3Exhaust wheel Energy from exhaust heat and pressure spins a turbine called the exhaust wheel
4Shaft A shaft connects and supports the exhaust and compressor wheel
5Compressor section Incoming air is pumped through the compressor section of the turbo.
6Compressor wheel The spinning compressor wheel draws air into the compressor chamber and builds compression.
7Air intake manifold
8Air intake pipe
9Air filter
10 Turbo housing & scroll shap
The turbine and compressor chambers have a spiral shape like a rolled up scroll, though the term “scroll” in connection with turbos often refers to the exhaust chamber (i.e.: twin-scroll).
