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.
