But what exactly does a dump valve do, and how does it work? Also known as a blow-off valve, this equipment regulates boost pressure. When your turbo is running at full speed, it cannot slow down instantly because the intake system is still pressurised. If this pressure is not released, it returns to the compressor, risking damage by reversing the direction of the compressor wheel. The dump valve, mounted on the intake pipe, uses a spring-loaded diaphragm or piston to release air in the event of excess pressure. Once the air is released, you can therefore change gear without losing boost, ensuring continuous power delivery!
