[QUOTE="SlowSVT, post: 14879687, member: 20202"] Malcolm I have no experience with gapless rings but did my homework before deciding whether or not to run them. In the end I came away with the impression the advantages outweigh the disadvantages [U]in most situation[/U] for our intended use. This pressure build-up between the lands seems plausible but what is the bottom ring have left to do while the 2 thin stacked rings are taking the brunt of the heat and pressure? There is more to this story placing the gapless ring in the top land in this engine which has a few of it's own downsides in my opinion. Pose the question in mod fords. I am sure Ed Eshaider will chime-in. I've discussed this topic with Ed more than a few times. He has a lot of first hand experience running Total Seal gapless rings and I don't think he will advocate running them in the top slot in a supercharged application on a street car. [/QUOTE]
