How important is a valve's role in your engine? As simple as it may seem, this is the doorway for all air being process in your engine. When we choose a valve for one of our race engines, there is much more than just picking a familiar name. How was it manufactured, what is the heat treatment process for the tip, what are the flow characteristics, does my valve manufacturer deliver a consistent product? How will it hold up to the abuse of high rpm and high spring pressures? For a turbo engine, how much heat can this valve take before it starts to distort and change shape? For an alcohol motor, is the material too brittle for cooler operating temperatures? If a head breaks off the valve, this little $15-20 piece can cost you an entire engine, and thousands of dollars. What about flow? If you ever read my tech article on head porting, you would have seen me mention that CFM gained in a cylinder port on a Honda can generate about 1 hp for every 2.5 CFM gained.....however, CFM picked up at the valve itself as opposed to other areas of a port can produce closer to 1 hp for every 1 CFM. Valve flow and controlling the motion of that valve is critical.

Ferrea Valves, the world’s leading manufacturer of racing valves, introduces the Sport Compact market into the already race-proven Ferrea 6000 Series Competition Valves. This Ferrea Valves Series is designed to provide excellent reliability in an environment of high RPM and high spring pressures, at a budget price. These valves have higher fatigue resistance and tensile strengths than our competitor’s best offering. The 6000 Series Competition Valves are specially designed for street, drag and rally racing applications. To manufacture the valves we use our exclusive two-step slow-forging process applied to the special alloys selected to suit intake and exhaust applications. We provide a unique heat-treatment and stress-relieving process, along with hard chrome stems and friction-welded hard tips. We finish the valves with a swirl-polished head. Ferrea Valves feature flow improvements to deliver the power needed for today’s sophisticated Sport Compact racing engines. |
