| Proper material choice for the application is crucial to the valve performance and reliability. The extreme change of temperature to a valve in the combustion chamber area (in excess of 1600ºF) and in the intake manifold area (up to -25ºF), can cause “thermal fatigue”. The material’s ability to resist these drastic thermal variations is crucial to the valve life. This is why Ferrea is constantly testing and evaluating new materials and processes to provide the highest level of “fatigue resistance” in the industry. Here is the growing list of materials that we use in the production of our valves: |

VALVE LENGTH CALCULATIONS Valve lengths are calculated as overall length measurements. This is the length of the valve from the stem-end tip of the valve to the combustion chamber face. Many of the Cylinder Head Manufacturers use a system that calls for valves to be +100, +250, etc. This is an additional length added to a stock valves for that application. This can sometimes create confusion, since some stock lengths have changed over the years due to slight OEM changes. For the purpose of the Ferrea Racing Components catalog the following will be used as stock lengths for the most popular applications. Understand that as components manufactured for the Racing Industry, many times margins and other measurements will differ from stock, to create better flow characteristics, and to improve durability. As an engine builder or cylinder head assembler, it is your obligation to check this with your setup for that particular cylinder head and assure that proper geometry is obtained. Many factors such as rocker arm choice and setup, seat machining and valve spring install height may create the need for a valve of different length than specified by either Ferrea Racing Components, or the cylinder head manufacturer. |

reduction in the valve train and a better dissipation of heat
from critical areas. We offer these Sodium Filled-Hollow Stem Valves as custom order production run quantity only. Please contact our Technical Department at 1-888-733-2505 or at ferrea@ferrea.com. |
| Ferrea’s Titanium and Tool Steel custom retainer program has grown exponentially in the past 3 years. We have expanded this program with newer updated automated precision CNC machines. These CNC machines give us the ability to custom manufacture lower quantities and competitive pricing for special programs in the performance and racing industry. Our engineering staff places specific designs and testing with each program to ensure the absolute best quality and reliability that comes with the Ferrea brand. The custom retainer program gives you the following advantage. |
| Ferrea offers the finest titanium valve on the market. Our extensive R & D facility is constantly implementing new designs and processes, which continue to keep us in the forefront of engine valve technology. We manufacture each valve by forging a special high temperature titanium alloy with silicon. This high-temp alloy is considered a “special upgrade” by our competitors; however, it has been the standard material in all of our exhaust and some intake valves for years. The valves then undergo an extensive heat treatment and stress-relieving process to ensure molecular integrity and prolong the valve’s life. Each Ferrea titanium valve is meticulously machined in our own precision CNC machining centers where it must pass extensive quality control procedures. Our proprietary Chrome Nitride (CrN) coating sets the standard for valve manufacturers around the world. Our unique CrN coating is applied uniformly to the entire valve, forming a protective insulating barrier from high engine temperatures. Ferrea’s CrN coating provides rapid heat dissipation to the valve guide surface, friction reduction, wear resistance, hardness, and allows dynamic valve train forces and valve flex stresses without delaminating or flaking. All of our special processes provide maximum performance and reliability, affording longer life in today’s professional racing engines. |
| (*) Additional wear resistant coatings such as CrN or DLC can be applied to valve seat and/or tip areas at an extra charge. Please contact a Ferrea sales representative for pricing. |
| Ferrea also offers Titanium Blanks Valves that can be custom-machined to your specifications. These custom valves can be produced with or without hard tips. We assure a fast turnaround time. Our selection of blanks now includes the New Special Hi-Temp, Nitrous compatible exhaust valves, unlike all other titanium valves, they will not flake, chip or peel at the bottom of the stem, due to heat or excessive movement. Stem diameters are available in 5mm – 8mm for use in Honda, Acura, Toyota, Nissan, and Aurora IRL motors. |
|
Ferrea super alloy valves represent the highest level of sophistication
in valve technology. These valves are designed to handle the
extreme heat requirements and punishment of today’s Nitro
Fuels, Supercharged, Turbocharged, Nitrous Oxide, and Marine
race motors. Many Top Fuel and Funny Car teams can confirm the performance and reliability of these valves which are now available for many engine combinations including Drag Race, Time Attack, Road Race, Endurance and Marine applications. We have expanded our selection of stem diameters from 5mm to 3/8 stem size for every specific engine combination. This allows us to improve our valve program in the Sport Compact market. Our manufacturing of small engine valves has led our involvement with race teams competing globally in World Rally Challenge, Drag Racing, Drifting and Road Racing. |
| Ferrea offers Super Alloy Blank Valves that can be custom-machined to your specifications. These custom valves can be produced with or without hardened tips. All of these valves come with hard-chromed stems. We assure a fast turnaround time and a high level of quality control and precision. Our selection of blanks now include stem diameters from 5mm – 3/8 inch. These blanks have lengths available up to 7.5 inches long, so we can make a short run of valves for most applications. |

One important factor to take into consideration to increase the
engine’s rpm’s, is the valve train weight. Of course,
being the valve a main component, the design has to be perfected
to accomplish the weight reduction to allow higher rpm’s. Ferrea’s latest contribution in this area is our Lightweight Hollow Stem Valves. We developed a proprietary manufacturing process that gun drills and micro polishes the bore of a valve stem. This proprietary process insures greater structural integrity than any hollow valve on the market today. This achieves a valve reduction in weight of approximately 20 percent compared to a conventional stainless steel solid stem valve. The valves also feature friction welded tips, radial grooves, avionics chrome plated stems, seat hardness up to 42HRc and Super |

Ferrea Racing Component’s Competition Plus Valves have built
a reputation as the industry’s most reliable racing valve.
We, at Ferrea, are dedicated to providing the absolute best product
on the market. Our extensive R & D programs provide technological enhancements that are implemented in each of our competition plus valves. They are engineered for high rpm’s, high horsepower racing engines, and are chosen by many top Drag, Oval Track, Road Racing and Sprint Car teams. To manufacture the valves we use 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 our molecular integrity. These valves feature avionics-quality hard chrome along with a specially applied hard tip. Our 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! The evolution in volumetric efficiency of today’s competition engines has increased the average engine EGT. These higher Exhaust Gas Temperatures decrease the longevity of the valves as well as creating higher levels of metallurgical fatigue. These increased stress loads create an environment in the engine conducive to valve failure. The exhaust valves in the Competition Plus series are manufactured from Ultra High Strength, High Temp Nickel Stainless Steel Alloys. Ferrea first used this material with great success during the development of a very high stress, high temp endurance racing program. Listed below are some qualities of the Competition Plus Exhaust Valve material: • Tensile strength increased by 20% at high temperature • Fatigue resistance increased by 20% • Valve seat life increased by 25% |
|
The 6000 Series Competition Valves are designed to provide excellent
reliability in an environment of high spring pressures and roller
cams, at a budget price. They have higher fatigue resistance
and tensile strengths than our competitor’s best offerings.
These valves can be used in Drag and Oval Track racing applications. To manufacture the valves we use our exclusive two-step slow forging process using EV8 stainless steel on both intake and exhaust valves. We provide a special heat-treatment and stress relieving process, along with hard chrome stems and friction-welded hard tips. We finish with a swirl polished head. The valves feature flow improvements to deliver the power needed for today’s sophisticated racing engines. These valves are available for both the traditional Domestic performance and racing engine market and the Sport Compact performance and racing market. |
|

Strict quality control procedures and cycle testing ensures consistency
from batch-to-batch. We have expanded our valve spring line offering PAC Alloy Beehive Ovate (Oval/Multi-Radius) wire shape designed to withstand aggressive endurance requirements. Key advantages in using an ovate wire shape are better heat dissipation for longer life, and valvetrain stresses are more effectively distributed over the entire wire shape extending spring life and enabling more horsepower. They have the highest level of fatigue resistance available, while minimizing load loss for today’s aggressive valvetrain combinations. PAC Racing develops beehive springs with aid of RPD (Rapid Prototype Development) technique to ensure that the engine runs as expected. Numerous spring designs are evaluated and tested before the final spring shape is determined. |
|
Harmonics or high frequency fatigue is present in all racing
engines and will usually destroy the valvetrain if not controlled.
Properly designed valve springs will control the dominant harmonics,
provide the needed stability, and reduce valvetrain component
wear. Ferrea Valve Springs are developed from high strength alloys, including premium grade chrome silicon steel. These springs are manufactured with state-of-the-art equipment. Our springs are heat-treated and stress relieved, which dramatically increases the spring’s life. Strict quality control procedures and cycle testing ensures consistency from batch to batch.
