LOL... but seriously...
OK, seriously. You are correct. The software cannot calculate other specs from only the lobe lift and base circle measurements.
The program can calculate the LSA (Lobe Separation Angle) from the Intake Centerline and the Exhaust Centerline.
For example, if you know the ICL is 106 degrees and the ECL is 112 degrees, the program will calculate 109 degrees for the Lobe Separation Angle. The program does not allow user input for the LSA… I’m not sure why. The algorithms used and how the mathematic calculations are programmed is above my pay grade.
The software can calculate 100s of data values.
The attachment is just 1 page of data that the program will produce!
