Vortech Maxflow BV57 Bypass Valve - Polished 8D205-008
Polished Maxflow BV57 Ultra-High-Flow Bypass Valve
The Vortech Maxflow BV57 Bypass Valve (PN 8D205-008) is a race-grade pressure relief solution built for extreme airflow, high-boost forced induction systems. CNC-machined from billet aluminum, the BV57 delivers a massive 1,300 CFM at 10 PSIG, making it ideal for high-horsepower supercharged and turbocharged combinations where conventional bypass valves become restrictive.
This configuration features a durable, high-visibility polished finish and is designed exclusively for speed density or blow-through Mass Air setups. The BV57 operates as a vent-to-atmosphere bypass valve and is not intended for re-circulation, ensuring rapid pressure relief and stable boost control under aggressive operating conditions.
Advanced BV57 Valve Design
The BV57 utilizes a large rolling diaphragm combined with a -4 AN signal hose connection and dual filtered vents to provide exceptionally fast valve response during throttle transitions. A unique valve head attachment method allows controlled articulation, ensuring a perfect seal against the mechanically retained valve seal even under sustained high boost.
