Williams Engineering, LLC

All of our manifold development starts with the fundamental principles of fluid mechanics in conjunction with actual testing via cfd analysis, flow benches, the engine dyno, and track data for measurement in error and improvements. Analyzing all of these variables carefully is where product refinement, knowledge, and experience increases with each manifold we produce. We consider every customers manifold a R&D project. We base the foundation of products and applications around these principles as a result of feedback from engine builders, tuners, dyno technicians, and racing teams. We will not push our theories on anyone. We simply provide what each customer wants and demands, with factural suggestions on potential improvements based on test data provided by the customer as related to their engine performance configuration.

each set of runners is custom designed to match any type of cylinder head port configuration. CNC runners provide precise and balanced geometry to each cylinder for improved volumetric efficiency. 5-axis machining allows us to control the inside surface finish and create contours that will optimize airfuel distribution into the cylinder head. Facts & Features Custom designed for each engine application Greater geometrical accuracy than sheet metal runners. Minimal distortion during assembly and welding Unlimited runner designs from round cross-section, to rectangular, oval and square ports with fillet radii. Nitrous bosses and curvedcontoured runners also available
