Introducing the Forge Piston Blow Off Valve, featuring a stylish silver finish to complement your vehicle's exterior. This premium upgrade from the factory valve is engineered for enhanced durability and superior performance under high boost pressures. With the option of an atmospheric valve available on many vehicles, you can now enjoy improved reliability as well as the iconic 'whoosh' sound associated with turbocharged engines.
When accelerating or decelerating on a turbocharged vehicle, the pressurized air trapped within needs to be effectively expelled. If not properly vented, this can lead to a delay in your turbo regaining boost, affecting overall engine performance. Forge Motorsport's advanced Blow Off Valves (BOV) are designed to address this issue by releasing built-up pressure promptly and reliably.
The stock valve may employ a soft diaphragm that can deteriorate over time, leading to leaks and performance degradation. Our BOVs replace these vulnerable components with robust materials for long-lasting reliability and optimal function.
For some applications, Forge offers both recirculating dump valves and atmospheric dump valves. Recirculating valves discreetly return excess air to the inlet without any added noise, while maintaining compatibility with increased boost pressure. Conversely, an atmospheric valve releases the pressurized air directly into the atmosphere, creating a distinctive exhaust sound. For selected vehicles, Forge has developed solutions to mitigate potential engine issues arising from this change.
It is important to verify the valve type in the product title, as recirculating valves will not produce the signature 'blow off' noise typical of atmospheric valves. For vehicles with an ECU-controlled dump valve, our kits include necessary wiring and connectors for seamless installation.
