Engine Pistons - Piston Rings
Piston rings are important fixtures for your engine pistons. The top ring provides a seal that helps maintain cylinder pressure and the bottom ring provides a barrier to prevent oil from leaking into the combustion chamber.
The key to a good piston ring seal is the finish on the cylinder wall and the condition of the ring grooves on the piston itself. Any cylinder pressure that escapes past the top ring is lost compression that won't be ignited during the engine's combustion stroke. Compression leakage equals power loss! Therefore, well-operating piston seals are crucial to the overall function of high performance engine pistons.
When choosing piston rings for your racing engine, there are many factors that come into play. Different piston ring sets will deliver different results on the street, track or desert. There are also other important considerations such as the choice of fuels, especially nitrous oxide.
A top choice for high performance racing engines is a Plasma Moly ring set. The top ring seats rapidly and maintains its seal under intense compression pressure. The bottom ring conforms quickly and prevents oil from sneaking into the combustion chamber. Another option is the SS50U stainless steel ring, which is a first choice for many builders of racing engines.
