At Ward Performance, we're dedicated to providing high-performance solutions for your motorcycle's engine. Our latest service, the CNC porting for the S&S and Harley Davidson 55mm Intake Manifold, is designed to take your engine's power to the next level.
During the development of this manifold, we focused on maximizing the flow between the front and rear cylinders. We discovered that by optimizing each leg of the manifold, even though they are not equal, we were able to substantially increase horsepower output.
To ensure the best results, we utilized a variety of testing methods. Our Superflow 1020 adapter allowed us to attach the manifold directly to the flow bench, while 3D printed radiused inlets were bolted directly to the manifold for testing purposes.
The results of our testing speak for themselves. Our CNC porting for the S&S and Harley Davidson 55mm Intake Manifold delivers unparalleled performance gains. Trust Ward Performance to help you unlock the full potential of your motorcycle's engine.
As you can see from the test results, the CNC ported intake manifold provides a significant increase in airflow compared to both the stock plastic and un-ported S&S and SE 55 manifolds. With an average increase of 22cfm, and up to 65cfm over stock plastic, our CNC ported S&S and Harley Davidson 55mm Intake Manifold is the perfect solution for achieving maximum horsepower gains.
