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.
