Porting Calculator V4.2.2 -

Optimizing 2-Stroke Performance with Porting Calculator V4.2.2

: Computes exact durations for exhaust, main transfer, and intake ports (including piston port and rotary valve inlets). Mean Area Analysis : Displays required mean port areas in cm2c m squared Porting Calculator V4.2.2

: 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 Optimizing 2-Stroke Performance with Porting Calculator V4

: 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

based on the current timing and target RPM, ensuring the engine can "breathe" sufficiently at high speeds.
