Sometimes bigger is just better. Designed for large capacity supercharged and turbocharged engines, including turbo-diesel engines, the Big Bubba is our largest and scariest Blow-Off Valve.
 

Big Bubba is available in two different styles, Bubba Sonic (Full time vent-to-atmosphere) and Big Bubba (Full time recirculating)

Big Bubba features:

• Precision machining and assembly – the piston and valve body are measured to mere fractions of a millimetre, and perfectly matched to fit each other exactly. Because of this precision, an O-ring is not needed to create an effective seal
• CNC billet aluminium body and components
• Huge 50.8mm/2” inlet and outlet
• Lightweight 52mm (2.05”) hard anodised aluminium two-piece piston
• -4AN threaded vacuum port
• V-band mounting system interchangeable with the Race Port
• Weighs only 790 grams (1.7lbs)
• Designed, manufactured and validated in-house at Turbosmart HQ

Supplied With:
Alloy Hose Adapter/Weld Flange, V-Band Clamp, and Green Spring Rated -12 to -8 InHg (installed).
