Valve Spring Tech
COMP Cams®

Valve Spring Tech

Revolutionary design features, such as the harmonic resistant shape, Super Clean™ ovate wire material and reduced spring mass, allow the Beehive™ Springs to better control the valve with a minimum of spring pressure. The bottom line in increased valve train stability, yielding more usable rpm and more horsepower than you ever thought was possible.

Design Quest

In our quest to offer the best products and services, COMP Cams® has spared no expense in personnel or equipment. This philosophy keeps us on the cutting edge of design and manufacture of all of our products. The result of our huge investment in personnel, expertise and equipment is no more evident than in the manufacture of COMP Cams® valve springs. From design to manufacture, COMP Cams® delivers advantages to you that are found nowhere else in the industry.

Design - From the Beginning

From a design standpoint, making a spring does not begin with our engineers. It actually begins with you, our customer. That may come as a surprise, but at COMP Cams® everything we make is based on what our customers need. That's why our design process begins by listening. Our technical sales staff is comprised of engine builders and racers who are uniquely qualified to listen and convey your real world needs to our engineering staff.

Design Collaboration

Once loads, heights and diameters are established, the process moves into a design engineering phase. Our spring design method engages every design and test engineer, manufacturing engineer and metallurgist on our staff. Each member of our engineering staff specializes in specific areas of valve train design. Their combined knowledge blends to create the ultimate spring for application-specific requirements. Simultaneously, our world-class metallurgists are integrated into the process to formulate the best materials possible for spring wire. They do this through analysis of materials on the molecular level. A concept is then turned into a blueprint through the use of the COMP Cams® advanced proprietary spring design software.

From Blueprint to Prototype

When the spring has been blueprinted, it moves from paper to prototype at our spring manufacturing plant. Prototypes are manufactured under intensive and rigorous standards and are then subjected to an extraordinary amount of analysis and testing in a full valve train set-up. This process is called system-analysis.

Superior Design for Superior Springs

If spring design is the heart of spring making, then system-analysis is its soul. System-analysis is the investigation of the valve train components as a complete mechanism or system. It includes the study of spring performance as it relates dynamically to the interaction of the camshaft, lifter, pushrod, rocker and valve in an engine while in operation. Understanding how a spring interacts with the entire valve train system is absolutely critical to designing an application-specific spring.

The mainstays of our spring analysis equipment are our Spintron® machines. These machines represent a sizeable investment in our design program, and as such, they play pivotal roles in design analysis. Functionally, a Spintron® is an electrically driven test machine. In the case of springs, it is used for the in-depth investigation and analysis of spring dynamics at any given rpm. These machines are capable of turning the valve train up to as much as 20,000 rpm and provide our engineers with a means of defi ning spring performance. It also provides computer data to verify correctness of each application-specific spring design. In tandem with the Spintron®, our engineers analyze springs through the use of lasers, strain gauges, load cells and high-speed video. Lasers show the cumulative effect of the valve train components at work. This allows our engineers to know that designed springs are in harmony with valve train set-up. Strain gauges and load cells are used to measure the forces on a spring. This permits the understanding of actual stress levels of a spring in operation. By looking at the high speed video valve train movement in super-slow motion, our engineers are able to observe, analyze and assess spring dynamics.

Each prototype is also analyzed on our Computer Driven Spring Analysis System (CDSA). This equipment accurately measures spring loads at different heights. By doing this, they are checked against the design specifications. Data from the CDSA verifies that a prototype spring design is correct for the specific application. This data not only confirms the correctness of design, it also provides a database that's used in the full manufacture of springs. Every part of a prototype is measured and verified against the design requirements.
