Current piston ring packages center around .043-inch/.043-inch/3mm designs, but Total Seal is out to change that line of thinking with their new .9mm/.9mm/2mm ring packages.
“We’ve been using the old package for years, but we’ve taken a lot of our top-end diamond finish technology and trickled it into this new ring set,” says Total Seal’s Keith Jones.
The company’s new designs will be built into their Advanced Profile line of rings, and Jones says they will be affordable for the average user. The ring package uses a steel top ring, a ductile iron Napier-style second ring, and are light and low drag – up to 15 horsepower better than a typical .043-inch package, and for the same type of cost to the end user, according to Jones.
The top ring uses the company’s C33 Particle Vapor Deposition chrome nitride coating on its barrel face, which is a hard coating, but not extremely hard like titanium or DLC, in order to seat up quickly on the cylinder wall. Jones says the ring doesn’t run the risk of dirt particles impregnating into the finish, and the stainless steel design means that corrosion won’t be an issue. The PVD coating won’t flake or chip off.
Gaining more horsepower from a simple set of piston rings has been covered here on EngineLabs in the past, and as the ring manufacturers and piston manufacturers continue to adopt this OE-style technology for the aftermarket, the enthusiast stands to see a gain horsepower and performance with no reduction in longevity.
