Ferrea Racing Component’s Competition Plus Valves have built a reputation as the industry’s most reliable racing valve as they are dedicated to providing the absolute best product on the market. Ferrea's extensive R & D programs provide technological enhancements that are implemented in each of their competition plus valves. Ferrea valves are engineered for high RPMs, high horsepower racing engines, and are chosen by many top Drag, Oval Track, Road Racing and Sprint Car teams. To manufacture the valves, Ferrea uses special aerospace quality alloys, including the EV8-Z18, which provides high tensile strength. An exclusive two-step slow forging process ensures proper grain flow and virtually eliminates any damage to the material structure. The valves are then heat-treated and stress-relieved over a 48-hour period, which is the crucial base of their molecular integrity. These valves feature avionics-quality hard chrome stems along with a specially applied hard tip. The engineering staff at Ferrea spends countless hours conducting flow bench tests to achieve an optimum balance of flow, velocity and efficiency in the design of these valves. As a result, these valves incorporate smoother radiuses and unique undercuts. These exclusive features are what make the Ferrea Competition Plus Valves unequalled in performance and reliability and are ideal for use in top level competition in Drag Racing, Oval & Sprint Car, Road Racing, Sport Compact, Motorcycle and Marine applications.
