Big Bubba From Turbosmart exists because sometomes Bigger is Better! Big Bubba is a piston style valve for large capacity supercharged and turbocharged engines including diesels! If you’re looking for an inconspicous valve for a small capacity, low loost daily driver, you will need to look elsewhere!
Turbosmart’s Boost-Balance System means the more boost you feed this valve, the better it closes and seals – It is literally as simple as that. The 2 inch piston design is an expansion of our traditional BOV5 design, simply expanded to provide big flow and fitment options.
