I have never seen anything like that before. There is
more detailed
information about this idea available for people reading this. I am definitely going to give this a try. I wonder if aerohead would have anything to say as to optimizing the shape/angle of the groove(s) cut to encourage vortexes? This is a very exciting and compelling new idea for me. I'm going to have Darin change this thread name to something more appropriate since we're beyond the piston ring group buy and it kind of became a specific discussion on G10 internals.
