Engine Pro has announced the latest addition to its line of black nitrided high performance engine parts— Nitro Black race rings. Engine Pro president Don Weber says that Nitro Black performance rings were developed to offer advanced features usually found in very expensive performance race rings but at affordable prices.
Weber says the two top rings and the oil rails are made of black, gas nitride hardened stainless steel which creates a super smooth surface for maximum sealing. The faces of the top ring and oil rails are ceramic PVD coated and have very low coefficients of friction and also provide superior scuff and heat resistance and excellent seating. The second ring is a Napier design for optimum durability and oil scraping ability under the most severe performance conditions.
The Nitro Black rings are especially well suited for turbocharged, supercharged and nitrous engines. He says traditional cast rings can lose tension and ability to seal under extreme heat. This can result in a loss of power but can also allow a very small amount of oil to be burned in the combustion process. The resulting detonation can cause total engine failure in boosted engines. The black nitriding and ceramic PVD are completely compatible with all fuels, injections and Nikasil coated cylinder bores.
