dump valves & adaptors

By releasing excess pressure, dump valves help prevent the turbocharger from stalling or suffering damage. Some enthusiasts even claim that dump valves can improve throttle response and overall performance. Atmospheric dump valves are known for their distinctive "whoosh" sound when they vent pressure, which is a popular feature for some drivers.

​

Our dump valve adaptors allow you to modify the functionality of a car's existing dump valve (or blow-off valve) on a turbocharged engine, typically by changing where the released pressure is directed, often to create a louder sound or to fine-tune the valve's operation for performance purposes. Essentially, it acts as a connector that allows you to fit a different type of dump valve to your car's existing system.
