: Models higher sonic waves, targeting 300 to 350 FPS to scavenge spent exhaust gases efficiently. 3. Valve Lift vs. Curtain Area Optimizer
Follow this systematic workflow to use version 4.2.2 for a cylinder modification project. Step 1: Baseline Measurement
All dimensions are entered in unless otherwise specified on the front panel. Stock engine parameters are entered on the top row of controls. Port heights represent the distance between the port roof and the top of the barrel. Input fields are displayed in green, while calculated outputs appear in red for clear visual differentiation. Porting Calculator V4.2.2
Ensure that your Barrel Adjust value accurately reflects combined deck height, cylinder head squish, and base gasket thickness. Many discrepancies between calculated and actual port timings trace back to incomplete inclusion of these mechanical variables.
Porting Calculator V4.2.2 is an analytical software application built for two-stroke engine development. It translates physical engine measurements into critical timing values. Two-stroke engines rely entirely on the physical dimensions and positions of their ports to control gas flow. This software eliminates manual mathematical errors and accelerates the development cycle. Core Architecture : Models higher sonic waves, targeting 300 to
The software utilizes the classic piston displacement formula:
The is a specialized engineering tool designed for two-stroke engine modification, primarily used to simulate and optimize engine porting specifications for increased performance. It is part of a lineage of software that allows engine tuners to transition from "cut and try" guesswork to data-driven "time/area" calculations. Core Functionality and Features Curtain Area Optimizer Follow this systematic workflow to
Porting Calculator V4.2.2 is a specialized engineering software designed for two-stroke engine enthusiasts and professional tuners to optimize cylinder port timing and geometry. It bridges the gap between complex engine physics and practical mechanical modifications by calculating the critical relationships between port heights and durations.
Some users recommend setting Barrel Adjust to 0.00 mm and accounting only for the base gasket thickness to achieve accurate results.
The version 4.2.x series focuses on calculating the physical and temporal relationships between various engine ports. Key features include:
You can lock the relationship between transfer and exhaust ports so that changing one automatically calculates the necessary adjustments for the other. 3. Port CAD and Shape Design
