If you need help calculating
The software allows you to work forward from physical measurements or backward from a performance target:
In the world of two-stroke tuning, "pretty" ports do not always equal power. As noted by experts on community platforms like Facebook , many tuners focus on polishing areas that don't affect performance. Porting Calculator V4.2.2
The calculator uses the slider-crank mechanism formula to convert the distance from the top of the cylinder (TDC) to the top of a port into degrees of crankshaft rotation.
Enter the distance from the top of the barrel to the port roof to find the current timing in degrees. If you need help calculating The software allows
Tuners can input an expected Brake Mean Effective Pressure (BMEP) to estimate horsepower or kilowatt output.
Input your foundational engine parameters into the blue variable cells: Bore and stroke dimensions Number of cylinders Peak target RPM Valve diameters Step 2: Analyze Cross-Sectional Area (CSA) Enter the distance from the top of the
Measure your stock cylinder heights, port widths, and current deck height.
