The Race Port is famous for being 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 is type on the market.
The supercharger-specific Race Port features a soft spring so it can stay open at idle, when the supercharger is still producing a boost.
