Tial's beautiful Q blow off valve is CNC-machined from 6061 aluminum alloy and features a large 1.98 in (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 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 a 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.
Through countless hours of R&D Tial has been 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, and the only BOV we reccomend! Save your turbo(s)!
Comes standard with the 6psi spring (-8 to -11 in/Hg Vaccum opening).
