TiAL BOV for sale

Adding a 50mm blow-off valve to your car is like having an extra pair of hands on the road.

This standard TiAL 50mm BOV allows your engine to produce more power and torque by eliminating the unwanted boost pressure. This eliminates heat soak and reduces supercharger clutch wear. It also makes sure you get rid of any significant RPMs at idle/normal use without worrying about damaging other components.

With countless hours of R&D (research and development) by TiAL’s engineers, this is now the highest flowing BOV on the market. Offering a variety of good quality springs for different vacuum levels and one specially made just to deal with supercharged vehicles, this product delivers as promised. We’re proud to offer the latest generation of TiAL blow-off valve products.

Features

  • The body and all internal components are CNC-machined from 6061 aluminum alloy. It features a large 50mm valve with a dedicated valve stem/valve seal.
  • An aluminum or mild steel weld base mounting flange is furnished with each unit. Stainless Steel hardware is available at additional costs for total supercharger reliability and durability. The use of 6061 aluminum allows the housing to be anodized with a selection of colors.
  • Flows a staggering 60% fuel ratio more than the original design - that means 60% more air is blown off in the size valve flow! This is the highest flowing BOV on the market.
  • Quick actuator response.
  • A single Q BOV can support up to 1,800hp
  • -2 psi spring for supercharged applications
  • Spring Pressures: -2psi, -6psi, -8psi, -10psi, -11psi, -12psi
  • Thread: M10 x 1.0

Applications

  • Universal blow-off valve

What's in the box?

  • Q Assembly
  • TiAL Vband Clamp
  • Vband Weld Flange

Excellent BOV

Coming from the tried and true greddy type r, I was skeptical of this bov at first. Read on a forum somewhere that the springs recommended on the spring chart tend to be too heavy. Chart recommended 11psi for my idle vacuum. Bought an extra 8psi spring and installed. Spring was too soft and valve was open at idle. Fitted the 11psi(as recommended by tial) and it worked beautifully. No partial throttle flutter, valve was closed at idle, blow off was crisp, loud and immediate. (Sounds like the crack of a whip). So if you’re wondering if the spring chart is accurate, yes it is. Product is of good solid quality and anodized finishing is excellent. No regrets with the purchase. Highly recommended. Looks great in the engine bay too.
