TiAL Sport Q BOV

The first revision of the nine year old original TiAL Blow-Off Valve.


- The "Q" BOV bolts right up to any standard TiAL flange, no re-welding needed
- It flows a staggering 60% more than the original design, which means 60% more air is blown off per cycle
- This is the highest flowing BOV on the market. For use on turbocharged and supercharged 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 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 supplied with each unit or a mild steel version can be ordered instead
- 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 alloys 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, Black, 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.
