## Description

The TiAL Q Blow Off Valve is the first revision of the original TiAL BOV and it will bolt right up to any standard TiAL flange, so no re-welding is needed. This is a universal blow off valve for use on any turbo-charged or super-charged application (Paxton, Vortec, etc.). With a TiAL 50mm Blow Off Valve in place you can improve the long term durability and reliability of your turbocharger by preventing compressor surge during closed throttle and high vacuum conditions. What's Inside the Box? - TiAL Q BOV Assembly - TiAL aluminum V-Band Clamp - TiAL V-Band Weld Flange - TiAL High Pressure O-Ring - TiAL Banjo Type Air Fitting/Bolt - 10mm Hose Barb for quick actuator response

## Features

- About this item
- 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.
- A single Q BOV can support up to 1,800hp
- 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.

Love the sound. Switched from a tial that was just a swoosh of air. This works great and has an awesome fluttering sound.
