Porting Calculator V4.2.2 is a specialized digital engineering tool designed for engine builders, machinists, and automotive enthusiasts. It calculates critical cross-sectional areas, target air speeds, and velocity profiles required when grinding and shaping intake and exhaust ports.
(Brake Mean Effective Pressure) to achieve specific peak power bands. 6. Conclusion
: Users can load image files (PNG or JPG) of a port trace. By setting cursors to calibrate pixels-to-millimeters, the program calculates chordal widths and heights directly from the image.
The software utilizes engine geometry to provide performance predictions and modification requirements. Geometric Inputs
: Use the "Raise Barrel" control to adjust the barrel height in 0.1mm increments (or 0.01mm using arrows) to see how it shifts port durations. Porting Calculator V4.2.2
: Buttons like "Clear Mods" or automated offsets for boost ports relative to main transfers. Output Units
: Includes a "raise barrel" control to simulate the effect of cylinder shims or base gaskets on timing, with adjustments down to 0.01mm increments.
The red slide switch located to the left of the displays determines whether the program calculates port height adjustments or port durations. The selected displays will turn red (outputs), while the unselected displays become green (inputs).
A specialized control allowing simulation of raising the barrel from -2mm (at 39.2mm stroke) up to -5mm (for 99mm stroke) and corresponding upper limits, in 0.1mm increments. Porting Calculator V4
