Outlet fitting size: 50 millimeter (2.0 inch)
Big Bubba as its name suggests, big, bold and in-your-face. It is the largest valve in the Turbosmart range. But it is not all about the size and looks. With a heavy duty, CNC billet aluminum body and components and a 52 millimeter (2.05 inch) hard anodized aluminum two-piece piston, Big Bubba gives a new meaning to the term "hardcore". A -4AN threaded vacuum port offers a wide variety of connection methods. Outlet fitting size: 50 millimeter (2.0 inch). To make things easy it is ensured that all Big Bubba valves use the same inlet flange and V-Band clamp as the Turbosmart Race Port. All that in a package that weighs only 790 grams (1.7 pounds).
