Second generation blow-off valve from Nuke Performance, with ground-breaking function and even faster response. Highest possible flow capacity and unmatched performance.
BOV50c is the upgraded version of the classic Blow Off Valves from Nuke Performance. Uses the same flange as the old one, a quick and easy change without the need for new intake pipes. Its 50mm (1.97") valve and superior improved diaphragm ensure fast response and precise boost release.
• Improved reinforced diaphragm technology
• Fast response and precise boost release
• Billet aluminum V-Band clamp and flange included
• 1/4 BSPP top mount vacuum port
• Replaceable setting spring, supports 250 to 1600hp+
• Lightweight blow off valve for motorsport installations
Equipped with a low friction valve guide, the BOV50c V-Band blow off valve offers an extremely fast response and is ready for some serious boost and power.We believe this upgraded version of the popular first generation dump valve has the highest flow capacity for an atmospheric blow off valve.
• Easy to connect to your intake manifold with the included V-Band flange and clamp, safe and secure installation even when pushing your engine to its limits.
Nuke Performance Blow Off Valve The BOV50c V-Band comes with an included aluminum billet V-Band clamp and weldable aluminum flange.This provides a safe and secure installation even when pushed to the limit.
• Aluminum 60mm V-Band clamp and flange included
• Optional 51mm (2") hose fitting available - mount the V-band to your silicone hose
A stainless steel flange is included available if needed and we also have a 51mm (2") hose adapter (available here) ) that allows you to mount the blow off valve to a silicone hose without the need for welding or custom fabrication.

• What is the purpose of a blow-off valve, and how it works
An atmospheric (like the BOV50c from Nuke Performance ) releases the boost into the atmosphere when the throttle closes, preventing compressor shock and ensuring turbo life.A BOV is critical to turbo life but also plays an important role in improving performance spin up faster when the throttle valve opens again.
The required vacuum reference "detects" the throttle valve closing, which prompts the valve to open and release excess boost. The Nuke Performance BOV50c uses an oversized 1/4 BSPP vacuum port, which ensures that the vacuum reading is accurate and fast.
