Technical Specifications:

• For use on turbo-charged and super-charged applications (Paxton, Vortec, etc.) The body and all internal components of the blow off valve are CNC machined from aluminum alloy. It features a large 1.98” (50.5mm) valve.
• The V-Band design aluminum mounting clamp gives a very clean and unique appearance. The clamp uses Stainless Steel hardware for a long lasting, corrosion-free appearance.
• The valve seal utilizes a high temperature resistant 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 hard anodize-coated for wear resistance.
• The Blow Off Valve also comes with a machined aluminum banjo-type air fitting and bolt, with oversized 10mm hose barb for quick actuator response. The actuator has a high temp silicone reinforced diaphragm for long life.
• An aluminum weld base mounting flange is furnished with each unit
• Through countless hours of R&D Tial was able to make the same size valve flow a staggering 60% more than the original design – that means 60% more air is blown off per cycle! This is the highest flowing BOV on the market
• A single Q BOV can support up to 1,800hp
• Anodized aluminum color options (Silver, Red, Blue, Purple, Black)
