** Used for supercharger applications only

Select the BOV spring pressure rating based on your engine´s vacuum reading at idle when the engine is at ideal operating temperature. Boost is unrelated to spring pressures; it is solely associated with vacuum. The lowest rate spring (Light Gray) is specifically designed for superchargers and is not intended for use with turbochargers.

The BOV50c uses enhanced diaphragm technology and low friction valve guidance to ensure swift response and seamless operation for any need between 200 to 1600hp+.
The 50mm diameter valve moves smoothly with minimal friction, thanks to the Teflon-treated hard anodized diaphragm guidance. This guarantees reliable performance even under rigorous use in motorsport applications.

 A single BOV50c supports anywhere between 200 to 1600hp+

The Viton seal together with the new superior enhanced diaphragm the Nuke Performance Blow Off Valve BOV50c V-Band has an unmatched swift response and seamless operation which promotes efficient turbo spooling and maximum performance. The new reinforced diaphragm ensures exceptional durability, reducing maintenance requirements.

The top-mounted 1/4 BSPP vacuum port gives you endless possibilities to connect the blow-off valve to your vacuum line.
With the 1/4 BSPP top-mounted vacuum port, it effortlessly links to your vacuum line for boost reference. We offer a wide range of fittings, including barb hose fittings, and quick-connect tube adapters, available in straight and banjo versions. To ensure precise functionality in line with our specifications, we recommend using a 6mm inner diameter hose or tube.

 What is the purpose of a blow-off valve, and how does it work?
An atmospheric (such as the BOV50c from Nuke Performance ) BOV releases the boost into the atmosphere when the throttle closes, preventing compressor surge and ensuring the turbo´s longevity. A BOV is essential for the turbo´s lifespan but also plays a significant role in enhancing performance. By releasing excess boost, the BOV prevents compressor surge and reduces lag by allowing the turbo to spin up more quickly when the throttle valve is opened again.

The needed vacuum reference "detects" throttle closure, prompting the valve to open and release excess boost. The Nuke Performance BOV50c uses an oversized 1/4 BSPP vacuum port, that guarantees that the vacuum reading is accurate and swift.
