Kraftwerks 155-99-1100 Large Billet Aluminum Blow-Off Valve 1.00 Inch Port

The Kraftwerks 155-99-1100 is a large body billet aluminum blow-off valve designed for high-performance forced induction systems. This premium BOV features a CNC machined billet aluminum construction with a black powder-coated finish for durability and a stealthy appearance.

Key Features:

• 37mm piston design for maximum flow and rapid response
• 1.00-inch (25.4mm) port size for custom supercharger and turbocharger applications
• CNC machined billet aluminum body and components
• Black powder-coated finish
• Piston-based design without diaphragm to prevent leaks and tearing
• Highly efficient compressor surge control
• Superior response to pressure fluctuations

Unlike traditional blow-off valves that utilize diaphragms which can leak or tear over time, the Kraftwerks BOV employs a robust piston design for enhanced reliability. This valve helps minimize bearing failure and wear in both superchargers and turbochargers by effectively managing compressor surge. Designed for custom race kits and high-performance turbo setups, this large body valve delivers the flow capacity and responsiveness demanded by serious forced induction applications.
