Porting Calculator V4.2.2

The software utilizes the classic piston displacement formula:

The button instantly reverts all porting changes, restoring the stock cylinder timing. This is invaluable for comparing multiple tuning iterations quickly. Porting Calculator V4.2.2

The utility of Porting Calculator V4.2.2 lies in its targeted feature set. It focuses strictly on variables that dictate two-stroke volumetric efficiency. 1. Port Duration Calculation It focuses strictly on variables that dictate two-stroke

Provides target blowdown periods based on desired RPM ranges. Prevents exhaust backflow into the transfer channels. 3. Chordal vs. Arc Width Conversions Prevents exhaust backflow into the transfer channels

Do you need help understanding the Jennings/Blair calculations?

Porting Calculator V4.2.2 bridges the gap between old-school hot rodding intuition and modern fluid dynamics. By accurately calculating your minimum cross-sectional areas and monitoring port velocities, it ensures every pass of your grinding burr translates directly to measurable horsepower and torque gains on the dyno.
