QR is the more compact recirculating BOV. Optional 1.00"/25mm, 1.14"/29mm (GTR), 1.25"/34mm (DSM/EVO, SUBARU), or 1.50"/38mm reciruclation 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 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 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 aluminun, mild steel, or stainless steel weld base mounting flange is available at an additional cost. The use of 6061 aluminum allows the housing to be anodized with a selection of colors.
-
Color anodized aluminum 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
