The purpose of the dump valve is a high performance automobile that uses a turbocharger. The dump valve is necessary to reduce engine and turbocharger failures. Compression surge is a phenomenon that occurs in turbocharged engines when the driver releases the throttle. The high-pressure air in the intake system is trapped, and excessive pressure is applied to the compressor.
When this happens, the compressor slows down, causing the turbo to stall. This phenomenon is usually noticed when the driver tries to accelerate quickly after a pressure surge. The dump valve allows the compressed air to be released into the atmosphere, and when it does, there is a noticeable "whoosh" sound. In addition, the dump valve can also return the compressed air from the compressor inlet back to the air intake. The dump valve reduces wear on the turbocharger and engine.
The dump valve, first introduced by Bailey Motorsport in 1997, uses a piston design. The DV24 is used on engines without an air flow meter and has a boost of 60psi. The DV34 and DV36 have a unique design that incorporates a trumpet-shaped outlet. The price of these dump valves ranges from $123 to $165.
Advantages
Piston type dump valves are more efficient and quicker to respond than diaphragm valves. This translates into increased power boost and better overall performance. It can also be used on a variety of engines with or without mass airflow sensors.
Disadvantages
The only disadvantage of using Bailey's dump valve is that if the dump valve is installed after the mass airflow sensor, it may result in a fuel rich environment. However, with proper installation, this problem can be eliminated and the driver can enjoy the benefits of the dump valve.
Forge Motorsports offers piston or diaphragm dump valves. Forge's diaphragm-type dump valve is similar to the piston type, but uses a rubber diaphragm to relieve excess pressure. This type of dump valve makes a hissing sound compared to the hissing noise of a piston-type dump valve. However, Forge Motorsport also manufactures piston-type dump valves for other turbocharged engines. Prices for Forge Motorsport dump valves range from $104 to $211.
Advantages
Forge's dump valves are manufactured to protect the turbocharger for a long time. They are made of billet aluminum metal to ensure that they do not shorten the service life. Forge dump valves can also be used in vehicles without or with mass airflow sensors.
Disadvantages
Forge's valves are a bit more expensive than other products. Dump valves have been known to cause carbon buildup on spark plugs and catalysts.
