Product Details

The Turbosmart Kompact Dual Port Blow Off Valve (also called a BOV, dump valve or compressor bypass valve) is a compact, lightweight blow off valve for turbocharged engines. It releases excess boost pressure when the throttle closes, which helps protect the turbocharger from compressor surge and keeps the turbo spooled for quicker response between shifts.

Key Features:

  • Dual port design: Vents pressure through two outlets and can also be set up to recirculate air back into the intake.
  • Compact, lightweight construction: Machined from lightweight alloy for easier fitment in tight engine bays.
  • Adjustable spring preload: Lets you tune the valve to suit your boost level and engine setup.
  • Fast, consistent response: Designed to open and reseal quickly, helping to reduce compressor surge.
  • Turbosmart engineering: Built by a respected brand in boost control and turbo accessories.

The Kompact Dual Port line gives performance and street-driven turbo applications a reliable way to manage boost pressure. It also gives the engine bay a clean aftermarket look. Choose the variant that matches your application.
