: Includes a "raise barrel" control to simulate the effect of cylinder shims or base gaskets on timing, with adjustments down to 0.01mm increments.
based on the current timing and target RPM, ensuring the engine can "breathe" sufficiently at high speeds. 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 : Includes a "raise barrel" control to simulate
: 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 : Allows for the design of various exhaust
: Compare the intake, transfer, and exhaust mean area values. This ensures that the engine can intake enough air/fuel, transfer it effectively, and exhaust it without restriction.
: 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.
While earlier versions like Porting Calculator V4.2.1 laid the groundwork, V4.2.2 refines the user interface and calculation accuracy. The software is typically used by professional tuners on Windows-based systems, though mobile-friendly alternatives like Engine Tuning Calculator PRO offer similar 2-stroke and 4-stroke tuning capabilities on the go. porting Calculator v4.2.2 - Page 2 - ATV Riders
