TiALSport Q-Series 50mm Blow-Off Valve - Universal Turbo & Supercharged Applications

The TiALSport Q-Series Blow-Off Valve is the next evolution of TiAL’s legendary BV50, engineered to deliver unmatched airflow and response for high-horsepower forced induction builds. With a massive 60% increase in flow over the original design, the Q-Series stands as the highest-flowing 50mm blow-off valve available, making it the go-to choice for serious turbocharged and supercharged applications.

Precision CNC-machined from aluminum alloy, the Q-Series BOV features a large 50.5mm valve and a clean V-band mounting design that bolts directly to standard TiAL flanges with no welding required. High-temperature internal components, a reinforced silicone diaphragm, and hard-anodized wear surfaces ensure consistent performance, durability, and reliability even under extreme boost conditions. Capable of supporting up to 1,800 horsepower, this valve is built to perform where lesser BOVs fall short.
