TiAL QRJ Blowoff/Bypass Valve
(0 reviews)  

New for 2014 - The TIAL QRJ is our latest boost control valve. Designed with the needs of high performance recirculating systems in mind. The QRJ features a new body design, compact installation envelope, high-flow capacity, and configurable inlet and outlet ports.


  • 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 1.50 in (38.5mm) valve.
  • Optional configurations of Hose and or V-band connections for the inlet and outlet ports.
  • The valve seat 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 QRJ comes with our own machined aluminum banjo-type air fitting and bolt, with over sized 10mm hose barb for quick actuator response.
  • Color anodized aluminum options (Silver, Red, Blue, Purple, Black).
  • Multiple inlet and return port options for many install configurations.
  • Internal return spring pressure tuned for fastest response. Custom spring options are available for other configurations.
  • When Ordering, the Body, and 2 Flange sets will be selected.  [ Body #] + [ Inlet Flange #] + [ Outlet Flange #]


Included with every Tial QRJ:

  • QRJ Assembly

The QRJ can be configured with V-Band and Hose connections on either port.

  • V-Band in - V-Band out

The QRJ features TiAL's high performance diagram. Long cycle life, zero leakage & zero breakaway friction. For fast and reliable boost control.


TiAL QRJ to Q/QR Flange option does not include a mounting clamp and o-ring.  The o-ring and mounting clamp is required for installation for if you have a TiAL Q/QR flange on your intercooler piping.
