Dump Valve Big Bubba 50.8mm Sonic (VTA) Sleeper

Turbosmart Big Bubba 50.8 mm Sonic (Atmospheric) Dump Valve – Sleeper

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.

Sonic version with 100% atmospheric (vent-to-atmosphere) discharge, Sleeper finish (stealthy black). This isn't a discreet valve for a small engine here, flow comes first.

Extension of the BOV5 design with a 2.0''/50.8 mm piston for maximum flow. Body machined from billet aluminum, hand-built and tested in Australia. Boost-Balance technology with a positive-sealing O-ring, V-band clamp mounting, cap-adjustable spring preload. Several springs available (7, 12, 17, and 21 inHg: Purple/Blue, Purple/Green, Purple/Yellow, Purple/Red).
