Honda S2000 Project Car - S2000 Square One
Street Header
For a two-week stretch in April, Skunk2 had our S2000 at its compound in Norco, Calif., to complete R&D on its street header (right) for the F22C1 motor. Since the manifold is technically still under development, they were mum about any real details in design. But we did get Skunk's Dr. Charles Madrid to reveal that the primaries are about a foot longer than those of competing aftermarket headers. The tubes are longer because the Skunk header pairs off primaries in sequential firing order, that is 1 with 3 and 4 with 2, whereas the OE and most aftermarket headers pair primaries non-sequentially, or 1 with 4 and 3 with 2. The sequential pairing of primaries is preferred for ultimate power output in a Tri-Y, but because of the difficulties inherent in manufacturing this design for street engines, namely that the headers work best with primaries almost as long as traditional 4-to-1, it has proven more cost effective and space efficient for Honda and most aftermarket header producers to make manifolds that use non-sequential pairings. We can only assume that Skunk has found a financially feasible way to mass-produce these headers. View Related Article
