Looking for any feedback. Good and bad.
Thanks

This set was designed to run piston rings with a much thinner and reduced radial tension ring that frees up frictional power losses and the ring conforms to the cylinder bore better...... The lesser overall weight of a ring like this reduces the tendency to flutter during the piston directional change going from up to down....... The holes you ask about are gas port assist holes that use the cylinder pressure to force the ring into the bore on the compression stroke to help the ring seal up better..... The holes only go into the the back side of the top ring land and in no way go to the crankcase.Piston design newb question: what are the vent holes in the face of the pistons for? Does it vent to the crankcase? What does this achieve?
Thanks for the explanation. Would a design like this be used in a street / strip build or only race application? Are there longevity issues with this?This set was designed to run piston rings with a much thinner and reduced radial tension ring that frees up frictional power losses and the ring conforms to the cylinder bore better......

This is really geared more towards a race application with high rpm usage in mind, 8000+ with limited street use. We also will be using a vacuum pump to pull a negative pressure in the crankcase to help with oil control. Some of this technology has trickled down into todays current production performance engines. The piston and ring set-ups they use today are a lot different than 40 years ago.Thanks for the explanation. Would a design like this be used in a street / strip build or only race application?
