O-Ring Kit Big Bubba

Turbosmart Big Bubba O-Ring Kit

The Big Bubba is the largest-piston dump valve in the Turbosmart range outside of RacePort/ProPort/PowerPort, with a 50.8 mm (2-inch) piston and a supported capacity above 800 hp. It builds on the proven BOV5 design, scaled up to meet the needs of engines boosted by positive-displacement or centrifugal superchargers and large turbo-diesels, which demand more flow than a standard BOV5 can provide. Aluminum V-band construction, no-removal cap-adjustable preload, and 4 spring options covering 7 to 21 inHg of opening pressure: the Big Bubba is reserved for serious builds, not an ordinary road car.

Replacement O-ring kit for servicing Turbosmart Big Bubba dump valves. It restores the positive seal of the 50.8 mm piston and extends the valve's service life.

Wear part to replace during periodic maintenance to maintain a perfect close and prevent boost leaks.
