Wilson Manifolds has applied the same technology used in our one-off custom designed billet bank sheet metal racing manifolds to our new line of Limited Production Billet Bank Sheet Metal Manifolds. By producing these select manifolds on a limited production basis, we are able to provide a much more affordable manifold that fits the most popular cylinder heads and produces excellent overall performance in many high performance and racing applications, particularly with larger displacement and/or high RPM engines. They also look great on street rods and show cars and are designed to fit under stock hoods. These manifolds are ready to bolt on out of the box and are designed to accept Wilson Manifolds high flow throttle bodies and ultra high flow fuel rails as well as Nitrous Pro Flow direct port nitrous systems and manifold pressure relief valves. These designs were developed using our state of the art solid modeling software, and each manifold’s cylinder banks (flanges and runners with integral injector bosses, stanchions, and direct port nozzle bosses) are machined from billet 6061-T6 aluminum on our simultaneous 5-axis CNC machining center. Each manifold is then precision fixtured and heli-arc welded for a perfect fit and maximum structural integrity. This production method allows for optimum runner to runner and manifold to manifold consistency in terms of both geometry and performance. Contact Southeast Performance for more custom applications.
