A **turbocharger** is a device that forces more air into an engine's combustion chamber, allowing it to burn more fuel and produce more power. It consists of two main parts: a **turbine** and a **compressor**. Exhaust gases from the engine spin the turbine, which is connected to the compressor by a shaft. As the turbine spins, it drives the compressor, which compresses and forces more air into the engine. This process increases the engine's efficiency and power output.

In high-performance cars, especially in racing or car chase scenarios like the one in your Unreal Engine project, turbochargers are often used to give vehicles an extra boost of speed and acceleration. The downside is that they can introduce **turbo lag**, which is a delay in power delivery as the turbocharger spools up.
