Tial QR Recirculating Blow Off Valve

The Tial QR Recirculating Blow Off Valve is a high-performance upgrade designed for vehicles requiring precise air management. Based on the TiAL Q series, this valve offers seamless integration with both the Q and original BV50, providing an adaptable solution for various applications. With a range of springs available for different vacuum levels and a specialized spring for supercharged vehicles, the QR ensures optimal performance across the board.

Key Features and Specifications

The Tial QR features a variety of recirculation port sizes, including 25.4mm, 29mm, 34mm, and 38.1mm, making it compatible with a wide array of vehicles. It utilizes the standard TiAL V-band flange and can be easily converted into a standard Q BOV with a simple swap of the bottom piece. Constructed from CNC-machined 6061 aluminum alloy, the QR is suitable for both turbocharged and supercharged applications, such as Paxton, Vortec, and others. Its V-band design and stainless steel hardware provide a durable, corrosion-free appearance, while the Viton O-ring and Teflon-lubricated valve stem ensure long-lasting performance.

Included Components and Customization

Every Tial QR comes with a comprehensive package, including the QR assembly, TiAL V-band clamp, V-band weld flange, TiAL air fitting, high-pressure O-ring, and a return fitting of your choice. The valve also includes a custom-machined aluminum banjo-type air fitting and bolt, with an oversized 10mm hose barb for rapid actuator response. The actuator features a high-temperature silicone Nomex-reinforced diaphragm for longevity. Available in anodized aluminum colors such as silver, red, blue, purple, and black, the QR can be tailored to match your vehicle's aesthetic. With a -2psi spring for supercharged applications, the Tial QR is a versatile and powerful addition to any engine setup. Please verify compatibility before purchase, as some modifications may be required for proper installation.
