1. not opening the piston window's till right AFTER the transfers open. (on down stroke)..
2. Closing the bottom of the piston cut right BEFORE the transfers open (on down stroke)
Playing some more.. I can get .839sqin of area (.419sqin per port) all without them opening untill the transfers are already open.. am I being a bonehead and missing somthing by having them open after the transfers?

I like this cut much better, with the tape covering the bottom of the piston window to delay them a bit more. It may even be beneficial to taper the opening of them a little more too, to create a smoother air flow transition from the air flowing though just the floor and side ports, to the floor ports, boost ports and the piston windows. That way there isn't a sudden pressure change just as the air starts flowing through the other ports. I will try my skillz at paint and see if I can draw what I am talking about. Basically the tape would be oriented at a slight angle, angling down towards the center of the piston, creating a "V" shaped piston port at the bottom vs a square-ish style shape. Other than this one thing (which may be tiddlywinks...), I think you have done a great job at maximizing the port area while maintaining the air differential at transfer port opening (on the down stroke).

Yesterday after working on the CR500AF I looked over at the rolling chassis that is my K5........got a bit sad to the point that sat on the K5 and made a bunch of "BRAAAP BRAAAP" noises.......I think I'm really starting to miss the ol' girl. :cry:
