4 Wheels - Road Tuning. When you come off the throttle on a turbocharged car the built up charge of pressurized air has to go somewhere. If it can't, or if the air isn't released quickly enough then the turbo will slow down or even stall leading to a delay getting back on boost when you get back on the throttle. This is where a dump valve comes in. It releases the built up pressure.
Most cars have a valve of some sort these days. This will have been tuned for the factory remap and factory boost levels though.
On many cars a soft flexible diaphragm is part of the valve and these wear out. The factory valve will be designed for quietness too.
Forge Motorsport offer a wide range of uprated Atmospheric Dump Valves / Blow Off Valves. These are designed to handle additional boost.
Because they are atmospheric, they release the charge of air with that distinctive "Whoosh" noise. Each valve is designed to do a very thorough job of releasing pressure, keeping your turbo spinning fast. Releasing to atmosphere rather than recirculating the air should help to keep inlet temperature down (because air coming out of the turbo is warmer than air from outside the engine bay).
Forge Motorsport offer properly engineered solutions with most of their products and these are no exception. Many modern engines have problems when you switch from recirculating to vent to atmosphere.Forge have, in most cases, engineered a complete solution to try and get around this. Forge are also offering complete kits for vehicles with ECU controlled valves (many newer VAG cars have this set-up). This means you can enjoy the sporty blow off valve noise on a wider range of cars than ever. For many of us that noise is all part of the fun a of a turbocharged car!
