Camshafts & Accessories

Camshafts in motorsport vehicles are critical components that govern the timing and duration of valve opening and closing, directly influencing engine performance. These camshafts are engineered from high-strength materials such as billet steel or chilled cast iron to withstand the high stresses and temperatures of racing conditions. The camshaft lobes are precisely ground to specific profiles that optimise airflow into and out of the combustion chamber, enhancing power output and torque. Performance camshafts often feature higher lift and longer duration compared to standard camshafts, allowing for increased air-fuel mixture intake and exhaust expulsion.

Accessories that complement camshafts in motorsport vehicles include valve springs, lifters, pushrods, and timing gears. High-performance valve springs are designed to prevent valve float at high RPMs, ensuring that the valves close promptly and accurately. These springs are typically made from advanced alloys that maintain their integrity under extreme conditions. Lifters and pushrods are also upgraded to handle the increased loads and stresses of a performance camshaft, often using lightweight, high-strength materials to reduce inertia and wear. Timing gears or adjustable cam gears allow for precise tuning of camshaft timing, which is crucial for achieving optimal engine performance.

The installation of performance camshafts and their accessories requires meticulous attention to detail to ensure proper alignment and function. Advanced timing setups may include vernier adjustable cam gears, which provide the ability to fine-tune camshaft timing for specific racing conditions. Additionally, camshaft sensors integrated into modern engine management systems enable real-time monitoring and adjustment, enhancing the precision of the camshaft's operation. Together, these components and accessories ensure that the camshaft performs optimally, maximising engine efficiency, power, and reliability in the demanding environment of motorsport.
