Our PSR Sport 50mm BOV is what we started using on our NC turbo systems several years back. This valve features a full reinforced silicone diaphragm for an ultra durable action. The preload and piston design leave this with a very sharp release action. You get a solid air release sound that's super FRIM. 

SPECIFICATIONS

• For use on turbo-charged and super-charged applications (Paxton, Vortec, etc.). The body and all internal components are CNC-machined from 6061 aluminum alloy. It features a large 1.98 in (50.5mm) valve.
• The V-Band design aluminum mounting clamp gives a very clean and unique appearance. This MATCHES the TIAL flange - The clamp uses Stainless Steel hardware for a long lasting, corrosion-free appearance.
• The valve seal utilizes a Viton O-ring that is clamped in place to prevent the possibility of sticking to the seat and pulling out. The valve stem and guide are Teflon-lubricated, hard anodize-coated for wear resistance.
• The Blow Off Valve also comes with our own machined aluminum banjo-type air fitting and bolt, with over sized 10mm hose barb for quick actuator response. The actuator has a high temp silicone Nomex-reinforced diaphragm for long life.
• An aluminum or mild steel weld base mounting flange is furnished with each unit. Stainless Steel is available at an additional cost. The use of 6061 aluminum allows the housing to be anodized with a selection of colors.
• Color anodized aluminum options (Silver, Red, Blue, Purple, Black).
• A single Q BOV can support up to 800hp
• -2psi spring for supercharged applications
