Calculator CFM Calculator

These 360 degree dual port single quad intake manifolds from Offenhauser feature completely separate runner systems for the primaries and secondaries. At low-load, the primaries feed the fuel-air charge through the smaller bottom passages at near sonic speed, improving power and efficiency. When the secondaries open, their charge goes through the bigger, cooler upper passages. Then, in turn, it is rammed into the cylinders when it encounters the high-velocity mix from the primaries. The result is better fuel economy, lower emissions, and a substantial power increase across the whole rpm range.
