What is boost in a car?

Boost in a car refers to the level of pressurized air or fuel mixture that is forced into the engine's combustion chamber to produce more power and torque. This is achieved through a device called a turbocharger or supercharger, which increases the air intake and compression within the engine.

Boost can be measured in units such as pounds per square inch (PSI) or bar, with higher levels of boost resulting in increased performance and acceleration. However, it is important to note that running too much boost can put strain on the engine and other components, leading to potential damage if not properly managed.

Drivers often use boost controllers to adjust and regulate the amount of boost being sent to the engine, allowing for more precise control over performance and ensuring the engine operates efficiently and reliably. Additionally, tuning the engine's fuel and ignition system is necessary to optimize performance and prevent engine knock or damage.

Boost is often associated with high-performance vehicles and is a common modification for car enthusiasts looking to increase horsepower and improve overall driving dynamics.
