this is not based on jennings or bikes. based on standard engine design formulas used in textbooks. porting is based on power level. physical dimensions of ports will need to be traced and measured properly. degree wheel necessary.
features: (what i have done so far)
-english measure units based.
-unit converter from metric to english units.
-swept volume calculator
-bore/stroke ratio calculator
-BMEP based power level gains between 25% and up.
-specific time area intake, exhaust, blowdown ......all complete.
-RPM based. Pick your peak torque rpm.
features currently working on:
-transfer time area for lower power, small cc engines
-transfer time area for higher power larger cc engines
-physical port area measurement calculators for different sized ports. (in metric and decimal inch).
-degree varience (baseline before porting degree wheel measurement) in 2 degree increments up and down.
-total sum of angle + port size. (if degrees are to be kept constant ...will figure physical port dimensions) also (if port dimension is to be held constant, will calculate degree change needed). based of degree varience of +4, +2, 0, -2, -4 degrees. this will ease the pain in the ass of guessing.
-transfer/blowdown ratio calculator
future ideas:
-transfer/blowdown ratio calculator
-exhaust/blowdown ratio calculator
-big motor program refinement
