A dump valve releases excess air in your turbo engine when changing from a boosted to a closed throttle state. To maintain your speed in-between gear changes, get bargain prices on a range of dump valves from CarParts4Less.co.uk.
The dump valve (or ?blow-off valve') sits between the turbo compressor and the throttle in your high-performance engine. When you change gear, your engine must close its throttle. Yet while the turbo continues to pressurise air, the closed throttle stops it from leaving the engine. The dump valve allows your engine to release this air. This prevents air pressure from reaching extreme levels, which in turn helps extend the life of your engine. Does your engine ?hesitate' when you change gear? Is it stalling, or do you see black smoke coming from your exhaust when you slow down? These are signs that your dump valve is faulty. When this time comes, find the perfect low-priced replacement at Car Parts 4 Less.
