In this [TECH TALK] Andre talks to Keith from Total Seal Rings about their gapless rings, the design of their rings and how they work better than a conventional ring. Covered is a brief history of the gapless ring and why we need a gapless ring when building high-performance engines in relation to blowby and leakage as well as oil contamination, or in Total Seals Gapless rings case, a lack of all these things. After all, as Keith mentions, no matter what other parts you have in your build, if your rings aren't sealing and helping draw as much air into your cylinders as possible, you're potentially wasting your time and money. Also discussed is a theory around the setup of the top rings and second ring where many suppliers and manufacturers advise leaving a bigger gap on the second ring to help avoid a pressure build-up and destabilisation of the top ring, known as ring flutter. Total Seals Keith explains that while the theory holds water, it’s not 100% true as the specific set of parameters required to cause ring flutter are very rare with misdiagnosis causing a lot of confusion around the topic. The decision process between a gapless top or second ring plus what sort of heat considerations and management should you be aware of with the different rings? With friction reduction in mind ring thickness and micro-welding along with the common causes of this are also touched on.
