How to make an Audi A4 turbo louder?
Elevating the boost pressure into your engine makes the turbo spin harder, spool up, and make a louder sound. Boost pressure is known as the additional air that is forced into your engine. You can get this adjusted by managing the amount of exhaust gas flowing via your vehicle’s turbo. The airflow to the intake manifold is low, but the air pressure from the turbo is high. Now this high air pressure should go somewhere, but there is no way to move forward. So this air pressure tries to escape back through the turbo. This process is called “Compressor surge” and we get this “stututututu” sound.
