The first revision of TiAL's original BV50 blow-off valve, the Q Series flows 60% more than its predecessor and bolts to any standard TiAL flange without welding.
An included weld mounting flange (available in aluminum, mild steel, and stainless steel) cut for 2-1/2'' pipe and CNC machined aluminum V-band mounting clamp with stainless steel hardware create a durable corrosion-free appearance.
A banjo-type aluminum air fitting and bolt with 1/4" hose barb allow quick actuator response.
Springs available to accommodate various vacuum levels and supercharged applications.
10PSI springs come in the blow off valve by default. BOV Springs are based on the vacuum your engine pulls and not by the desired boost level. Supercharged or big cammed engine applications may require a different spring. Please let us know if you require anything other than a 10 psi spring.
You also have your choice of color and flange material.
