Turbosmart Big Bubba Sleeper 50.8mm Universal BPV Bypass Valve - TS-0204-1203

Universal fitment for large-capacity turbocharged and supercharged engines, including high-output diesel applications.

The Turbosmart Big Bubba (TS-0204-1203) is a high-volume, piston-style bypass valve engineered for extreme performance builds where air-mass requirements exceed the capacity of standard valves. This Sleeper edition provides a discreet aesthetic while housing a massive 50.8mm (2.0-inch) piston designed to move massive volumes of air. CNC-machined from billet aluminum, it utilizes Turbosmart's Boost-Balance technology with a positive-seal O-ring to maintain pressure stability under high-boost conditions.

The valve mounts securely using an aluminum V-band system, ensuring a leak-free seal even in high-vibration environments. The cap features an adjustable spring pre-load for precise tuning, and the assembly is hand-tested in Australia to ensure reliability. This valve is designed for high-horsepower setups and is not intended for low-boost or small-displacement daily drivers.
