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.
A common amateur mistake is measuring port width along the curved cylinder wall (arc width). Porting Calculator V4.2.2 outputs the (the straight-line distance across the port). This prevents you from over-widening the port and causing piston ring snagging. 5. Step-by-Step Workflow for Engine Optimization
No software can replace the intuition and experience of a skilled engine tuner. The Porting Calculator V4.2.2 is a powerful assistant, but its output is only as good as its input.
: The calculator provides an Angle Area vs. RPM graph , allowing tuners to visualize the ideal power band for their current port configuration. Porting Calculator V4.2.2
Happy Porting!
The relationship between exhaust port flow and intake port flow, usually expressed as a percentage.
: The software highlights required changes in green, showing exactly how many millimeters a port needs to be raised or widened. Smolik Performance The software is currently available for purchase (approx. porting-programs.com The calculator uses the slider-crank mechanism formula to
Porting Calculator V4.2.2 assigns a .
: The port is too large. The engine will lose low-end power and throttle crispness. You must minimize widening or add material (epoxy/welding). Step 4: Export Dimensions to the Workshop
Calculator would just reject a number if it was "unavailable." V4.2.2 behavior: It now detects partial porting . If a customer has 5 numbers on a single account but only wants to port 3, V4.2.2 will flag that the account must be "unbundled" by the loss carrier first. This prevents you from over-widening the port and
Maps runner lengths to specific RPM harmonics. Key Features and Updates in V4.2.2
Optimizing 2-Stroke Performance with Porting Calculator V4.2.2
: Manual porting is often "cut and try," which can lead to permanent cylinder damage. The Solution : Software tools like Porting Calculator allow tuners to simulate changes before removing material. Theoretical Foundation
Choose between Metric (mm, kW, Bar) or Imperial (inches, HP, PSI) using the radio buttons at the top of the interface. 2. Port Timing and Calculations
