TiAL Sport Alpha Q Recirculating Blow Off Valve

TiAL Sport Alpha Q Blow Off Valve

  • 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; we believe this is the largest valve available with the highest flow capacity.
  • The V-Band design aluminum mounting clamp gives a very clean and unique appearance. The clamp is anodized and 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 where most cast aluminum allows can not be anodized. This allows the individual to match, or coordinate, the engine compartment color scheme. The clamp, valve, and housing will be offered in Silver, Titanium Gray, Red, Blue, and Purple to allow you to mix or match the clamp, body, and valve assembly to create a look unique to your application. You may also purchase a plain or unassembled unit to anodize or color-coat as you like.
  • The TiAL Alpha Q BOV is the first ever recirculating blow-off-valve offered by TiAL. This unique TiAL 50mm BOV flows 6% more than the current vent-to-atmosphere TiAL BOV
