Description
The camshaft is the heart of an engine’s valve train, precisely controlling when and how far the valves open and close. Its lobes determine valve lift and duration—two key specs that directly influence airflow and performance. Depending on engine design, camshafts can be located near the crankshaft and use pushrods, or mounted overhead to eliminate extra components for smoother operation. High-performance engines feature increased lift, longer duration, and optimized lobe separation for maximum power. Modern engines go even further with variable valve timing, allowing real-time adjustment of cam timing for ideal performance and efficiency. In essence, the camshaft isn’t just a moving part—it’s the core of engine breathing and the key to unlocking horsepower.
