Porting Calculator V4.2.2 !!top!! [ REAL ]

: 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

: Includes a "raise barrel" control to simulate the effect of cylinder shims or base gaskets on timing, with adjustments down to 0.01mm increments. Porting Calculator V4.2.2

The software provides a comprehensive suite of tools to manage the complex geometry of 2-stroke cylinders: : Computes exact durations for exhaust, main transfer,

: 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. : Computes exact durations for exhaust

: Enter your engine's stroke and bore. The software sets limits for barrel height adjustments based on these parameters.
