Turbocharging has revolutionized the automotive industry, allowing cars to achieve higher performance levels while maintaining fuel efficiency and reducing emissions.

Like other forced induction devices, a compressor in the turbocharger pressurises the intake air before it enters the inlet manifold. A turbocharger is made up of two main sections: the turbine and the compressor. The turbine consists of the turbine wheel and the turbine housing . It is the job of the turbine housing to guide the exhaust gas into the turbine wheel.
The energy from the exhaust gas turns the turbine wheel, and the gas then exits the turbine housing through an exhaust outlet area. In addition to the extra power, turbochargers are sometimes referred to as devices that offer “free power” because unlike a supercharger, it does not require the engine’s power to drive it.

he hot and expanding gasses coming out of the engine are what power a turbocharger so there is no drain of the engine’s net power. Turbochargers also improve the fuel efficiency of a vehicle however there is a misconception when it comes to turbocharged vehicles and fuel efficiency. Modern turbos contain complex systems that control how gases move through them to miniscule degrees of accuracy, giving more ‘linear’ power delivery and greater efficiency.
