Features of this specific product are as follows:

QR is the more compact re-circulating BOV. Optional 1.00" (Subaru), 1.14" (GTR), or 1.50" (DSM/EVO) re-circulation port, uses the standard TiAL V-band flange and can be converted into a standard Q BOV by swapping the bottom piece.

Specifications:

- For use on turbo-charged and super-charged applications (Paxton, Vortec, etc.). The body and all internal components are CNC-machined from 6061 aluminium alloy. It features a large 1.98 in (50.5mm) valve.
- The V-Band design aluminium 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 our own machined aluminium 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 aluminium or mild steel weld base mounting flange is furnished with each unit. Stainless Steel is available at an additional cost. The use of 6061 aluminium allows the housing to be anodized with a selection of colours.
- Colour anodized aluminium options (Silver, Red, Blue, Purple, Black).
- A single QR BOV can support up to 600hp.
- Multiple return port options for easy OE fit.
- 2psi spring for supercharged applications.
