Description
How Does a Turbocharger Work?
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.
The compressor also consists of two parts:
the compressor wheel and the compressor housing. The compressor’s mode of action is opposite that of the turbine. The compressor wheel is attached to the turbine by a forged steel shaft, and as the turbine turns the compressor wheel, the high-velocity spinning draws in air and compresses it. The compressor housing then converts the high-velocity, low-pressure air stream into a high-pressure, low-velocity air stream through a process called diffusion. The compressed air is pushed into the engine, allowing the engine to burn more fuel to produce more power.

And What are the Downsides?
Expensive Repair Costs
Turbochargers add complexity to an engine, with a whole host of other components beneath the bonnet that can fail or develop faults. These problems can be expensive to put right, and can have an impact on other components if they fail.
Turbo Lag
Turbo lag is a brief delay in response after pressing the throttle, which can occur when the engine isn’t producing enough exhaust gas to spin the turbo’s intake turbine quick enough. This only really happens when the car is being driven aggressively, or from a closed throttle position. In high-performance cars, manufacturers prevent turbo lag by adding two turbochargers of differing geometry, rather than one big one with only a single turbine.
