Gas ported pistons
Have any of you guys tried gas porting the pistons?
I was thinking about trying this, but I wanted to get some feedback first.

I thought about it but think in short time hole would fill in and throw ring pressure out of balance ,the top ring are cut at angle so that is your gas sealing

Is piston porting, like piston "windows" ?

Those pistons are for a piston induction motor....but yea the principle is the same. I was discussing this earlyer in which I use additional piston port induction to draw more intake as well as pushing cold fuel mixture under the crown. This is somewhat what I did to mine just not as big
I also champher the ports upwards so that the charge is forced upwards rather than downwards which most piston port induction motors use.

gas ported piston is where you drill small holes threw the crown to force explosion gases behind the rings to force them against the cylinder wall. like these
