Designed specifically for supercharged applications. The supercharger-specific Race Port features a soft pink spring so it can stay open at idle, when the supercharger is still producing boost.  The largest and the highest-flowing BOV in the Turbosmart range has just been redesigned and now features our unique collar design. 46% lighter and 25% smaller than the product it replaces, the new Race Port provides greater performance through faster turbo spool-up from idle and reduced turbo lag between gears.SUPPLIED WITH: Vacuum fittings, weld flange, V-band assembly, and Pink Spring Rated -24 to -14 InHg (installed).
