TiALSport 002581 Q Series 50 mm Blow-Off Valve 6 PSI Spring Silver - Universal

Vehicle Fitment

• Universal fit - designed for use on turbocharged systems that support a 50 mm blow-off valve mounting. Not vehicle-specific.

Features

• Precision-machined Q Series blow-off valve body with 50 mm diameter for high-flow turbo systems.
• 6 PSI (≈0.4 bar) spring preload for performance applications requiring moderate opening pressure.
• Silver-anodized finish for corrosion resistance and high-temperature durability.
• Direct-replaceable top cap, spring and internals allow tuning to specific boost/vacuum characteristics.
• Quick-response piston mechanism ensures consistent valve operation under varying boost loads.
• Compatible with both recirculating and atmospheric outlet configurations (selection dependent on plumbing).
• Ideal for high-boost turbo builds, custom applications, and serious performance tuning setups.
• Designed and manufactured to motorsport standards, offering reliability under sustained load and heat.

Product Description

The TiALSport 002581 Q Series 50 mm Blow-Off Valve offers a high-flow solution for turbocharged engines requiring robust boost control and efficient discharge. With a 50 mm bore size, this valve is well-suited to large-turbo applications, motorsport builds, and custom performance setups where standard BOVs may restrict airflow or respond slowly.

Pre-set with a 6 PSI (approx. 0.4 bar) spring preload, the valve opens cleanly under boost conditions while maintaining reliability under repeated high-load cycles. The silver-anodized finish not only looks high end but resists heat and corrosion typical in performance turbo systems. Because this is a universal part, you'll need to ensure your piping, flange, vacuum/boost port and outlet configuration match the valve's mounting requirements.

Ideal for performance enthusiasts building serious turbo systems - whether street, track or motorsport - you'll want a valve that flows, responds, and lasts. The TiALSport 002581 delivers all three. Note: As a universal component, installation may require custom plumbing or adapter hardware to match your specific turbo system. Be sure to verify dimensions, outlet style (atmospheric vs recirc), and boost target before purchase.
