Boost Pressure

Boost pressure refers to the increased air pressure in the intake manifold of an engine, achieved by using a supercharger or turbocharger. These devices compress the air entering the engine, allowing it to hold more oxygen. This extra oxygen enables more fuel to be burned, resulting in a more powerful combustion process. Essentially, boost pressure enhances engine performance and efficiency, leading to increased power output without enlarging the engine size. It's commonly found in performance vehicles and is a key factor in achieving better acceleration and overall responsiveness in cars.
