TiAL Q 50mm BOV

<h1>TiAL Q 50mm BOV</h1>


ARM Price $282.00

Product Code: TIALQ

Q is the first revision of the original TiAL BOV. The Q bolts up to any standard TiAL flange, no re-welding. This is the highest flowing BOV on the market. It's offered with a variety of springs for different vacuum levels and a special spring specifically for supercharged vehicles


  • 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 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.
  • Through countless hours of R&D we were able to make the same size valve flow a staggering 60% more than the original design - that means 60% more air is blown off per cycle! This is the highest flowing BOV on the market.
  • Color anodized aluminum options (Silver, Red, Blue, Purple, Black).
  • A single Q BOV can support up to 1,800hp
  • -2psi spring for supercharged applications

5 of 5 Top notch customer service and quality April 9, 2020
Reviewer: Nick from Mesa, AZ United States  
Now with this entire pandemic, you'd think that business would be ramping everything down to a halt but that's not the case with my friends at ARM. Not only did I get my BOV to accentuate my ARM downpipes, intake, and chargepipe- but I got it sooner than expected. Everyone says VRSF this and that. At the end of the day it comes down to this- quality. I'm not just talking quality of the perfectly machined parts you receive. I'm talking about the quality of service from the PEOPLE who are working at ARM. The boys out in the yard willing to personally email me and appreciate the business that I've given them. The very same people who- because I noted in my order all I'm missing is my intercooler- said "Hey, Nick. We appreciate that you're buying all these things from us. Shoot me an email when you go to grab an intercooler and I'll grab you a little discount as an appreciation token. Top notch services from the guys at ARM. I'm proud to rock their stuff. GET ARMD!

Reviewer: Kyle Coleman from Denver, CO United States  
Glad that I've purchased nearly everything from ARM to get to Stage 1+.

Would recommend anyone looking for bolt-ons to first look at ARM.
