Flange O-Ring RacePort/Big Bubba

Turbosmart RacePort / Big Bubba Flange O-Ring

Turbosmart is a leading Australian manufacturer specializing in turbo engine tuning, active since 1997 under the motto "Engineered to Win." A long-standing specialist in dump valves (blow-off valves), the brand designs, machines, and tests its products in-house to guarantee reliability, sealing, and performance.

According to Turbosmart, the RacePort is the highest-performing dump valve on the market in the 50 mm segment, thanks to an internal geometry that moves more air than competitors of the same apparent diameter, while remaining the lightest and most compact in its category, a decisive advantage in competition. V-Band mounting for secure fitment and quick removal during races. Available in VTA (atmospheric vent), Plumb Back (recirculating, popular off-road), EM (electromechanical, electronic boost management), and female-flange (compatible with existing competitor flanges) versions. It supports up to around 1,500 hp and covers the vast majority of high-performance applications.

Replacement flange O-ring for Turbosmart RacePort and Big Bubba dump valves. It seals the valve to its V-band mounting flange, preventing any boost pressure leaks.

Replace during valve servicing or if a leak develops at the flange.
