TiAL Sport Blow-Off Valve, Q-Series, 50mm, 11 psi Spring, Billet Aluminum, Black

TiAL's Q series is the most current revision of the original TiAL BOV. The Q bolts up to any standard TiAL flange, no re-welding. For use on turbo-charged and super-charged applications (Paxton, Vortech, 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. 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 PTFE - lubricated, hard anodize-coated for wear resistance.

The blow off valve also comes with TiAL's 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 weld base mounting flange is furnished with each unit. The use of 6061 aluminum allows the housing to be anodized with a selection of colors. 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. Proud to be made in the USA.
