Offenhauser Dual Port Intake Manifolds

The Offenhauser Dual Port Design is best described as two separate manifolds in one resulting in more power across the rpm range. The entire manifold is divided from the base of the carburetor to the head flange. In operation, the primary mixture is fed into the bottom runners and the engine operates on this smaller port until the engine demands more fuel. When the secondaries open, more fuel goes through the bigger, cooler upper passages. Fuel is then forced into the cylinders when it encounters the high-volume mix from the primaries. The results are better fuel economy and a 15-30 percent power increase across the entire rpm range.
