Dump Valve and Blow-Off Valve are the same parts as their uses, but Blow-Off Valve is the one which makes that exciting Whoosh! noise.
What is Dump Valve?This valve increases throttle response on a turbo charged engine,and reduces wear on the turbo. What's happening in an engine without Dump Valve?When you step off the throttle, the turbo is still spinning and is forced to stop very quickly, due to that the air has no where to go. When you then step on the throttle, the turbo has to rev up again. This takes time, and the car feels tired. |

How does it work?Now the valve comes to work. When you close the throttle, a vacuum is built up after the throttle. A hose goes from the inlet to the dump valve, and the built up vacuum sucks up a valve inside the dump valve, and releases the over pressure built up before the throttle. The air goes out into the engine compartment and creates a familiar sound you hear from turbo charged racing cars. When you then start to accelerate, the vacuum disappears, and the dump valve closes, and the turbo pressure is on top at once. The car feels a lot more powerful than before. |
Benefits of Dump Valve* The kit vents the turbo charger, and releases the air into the atmosphere, it also releases pressure on the turbo. |
