Benefits

• Valve Pocket designs that allow maximum flow around valve, also allowing oversized valves and high lift cams to be utilized
• Piston Crown shapes designed to promote maximum Intake Charge efficiency through scavenging mixture “Cross Flow” during intake and exhaust valve overlap. More fuel and air equals more horsepower
• Piston Domes designed for optimal quench during the compression/combustion cycle, resulting in resistance to detonation and preignition
• The end result is longer engine life and increased horsepower potential
• Precision machined ring grooves with proper orifice/accumulator volume feature calculated groove root diameters and axial widths, providing excellent surface finish and flatness, maximum ring seal and minimized blow-by and oil consumption
• World class, ISO Certified, forging facility that utilizes the latest technologies – Featuring complex forged shapes, advanced materials, and feature-aligned grain flow technology
• Complex Piston skirt profiles that reduce power robbing friction, yet promote stability in the bore for optimum ring seal
