TiAL "Blow Off Valve" for 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. (50.3 mm) valve; we believe this is the largest valve available with the highest flow capacity .

The V-band design aluminum mounting clamp gives a very clean and unique appearance. The clamp is anodized and uses stainless steel hardware for a long lasting, corrosion-free appearance.

The valve seal utilizes a Viton O-ring (viton is an elastomerthat 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 TiAL's 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.
