Four Stroke Design, Inc. is an engine design and consulting company that specializes in cylinder head and valvetrain design for high performance engines. State-of-the-art computer design and analysis software is utilized to model cylinder head geometry and valvetrain components in order to analyze the performance of the components before they are manufactured. Many design iterations can be performed and modifications made based on analysis without spending any money on manufacturing. This process is commonly known as Virtual Prototyping and is rapidly spreading globally as an efficient method in manufacturing. By spending money during the design process and saving time and money on the manufacturing process, our customers are able to maximize their return on investment and realize performance gains in a much shorter time period than by using traditional methods. We like to think of ourselves as an off-site development group for hire!
