 2 Stroke porting software for the enthusiast

 Porting Calculator V4.2.2

  For Windows 98, XP, NT and Vista

  Program features:

• Calculates port heights from durations, or port durations from port heights
• Assign fixed relationships between transfers and exhaust port. Enables all transfer
    port heights to be calculated automatically by just entering exhaust timing
• Exhaust and main transfer timing can be entered by mouse click on graph, or typed in
• Calculates required ranges of Jennings or Blair angle areas, mean areas and time areas
• Adjustable graph rpm scale: 7k scrollable range, adjustable from 1k to 18k
• Calculates possible ring flutter rpm
• Mean piston speed
• Suggests carburettor size
• Power meter (you input expected bmep value). Switch between PSI & HP, or BAR & kW
• Port design in separate cad window: enter shape values, or drag port cursors
• Limitations on CAD: Single exhaust port, single boost port

 Port map analyzer  V3.0

  Calculate your angle areas, mean areas, or time areas in minutes, directly from the portmap image:

• Load png or jpg port map
• Enter bore, stroke, conrod length and deck height
• Mouse click once on each port to start port trace
• Enter port height to top of barrel
• Set horizontal and vertical cursors to calculate image pixels/mm
• Enter port angles
• View exhaust and transfer rpm ranges in angle area vs rpm graph
• View time areas and power, with adjustable rpm and high-low tranfer bmep
• Change bmep and power units between psi/bar, hp/kw
• Measure portmap horizontal (mm, cord, %bore), and vertical (mm, crank degrees) distances

  You can add extra ports to the portmap image (eg using mspaint), load the new image and trace
  the new ports. The angle area graph has buttons to optionally turn these extra ports on and off, so you
  can quickly make a comparison of their effect without loading a new portmap. The graph also has
  a control to adjust barrel height.

  Max 5 exhaust ports, 5 boost ports. Total including main and aux transfers: 14 ports
