TiAL Q Blow Off Valve, 11 psi yellow Spring, Red Body, Aluminum Flange

#ad
TiAL Sport #ad - The valve stem and guide are Teflon-lubricated, hard anodize-coated for wear resistance. 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.

The body and all internal components are CNC-machined from 6061 aluminum alloy. The v-band design aluminum mounting clamp gives a very clean and unique appearance. It features a large 1. 98 in 505mm valve. 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. A single q bov can support up to 1, 800hp. For use on turbo-charged and super-charged applications paxton, Vortec, etc.
