: Enter your engine's stroke and bore. The software sets limits for barrel height adjustments based on these parameters.
: Once timings are set, use the port CAD window to define the physical shape (roof curvature, max width percentage) and save the design as a PNG for actual machining. Technical Requirements Porting Calculator V4.2.2
: Use the graph cursors to set desired durations. For example, durations above 150 degrees typically set the exhaust port, while those below 150 target the main transfer. : Enter your engine's stroke and bore
: Allows for the design of various exhaust shapes, including rounded rectangles, egg shapes, and D-shapes, as well as complex 2 to 6 transfer port configurations. including rounded rectangles
