The RacePort Series Blow Off Valve is an amazingly small and light BOV for supercharged competition level engines. Featuring our unique collar design and internal flow structures, it is 50% lighter and 25% smaller than the competition while flowing 330 CFM – making it the highest flowing BOV of its type on the market.

These ‘Female Flange’ Variants are designed to fit peer/competitor flange systems for ease of changeover & do not include a weld-on mounting flange.
