This high-performance valvetrain system makes use of a sturdy belt-driven design manufactured by Jesel for Massive Block Ford (BBF) engines. It replaces the normal chain or gear-driven camshaft actuation with a toothed belt, providing benefits by way of diminished friction, improved timing accuracy, and elevated horsepower potential. This technique is usually present in high-performance or racing functions the place these advantages are essential for maximizing engine output and reliability.
Diminished harmonic vibrations, a typical situation with chain methods, contribute to extra secure valve timing at larger RPM. This stability permits for extra aggressive camshaft profiles and better engine speeds, translating to elevated energy and a broader energy band. Moreover, the decrease frictional losses in comparison with conventional strategies unlock horsepower that will in any other case be consumed driving the valvetrain. This expertise represents a big development in valvetrain design for BBF engines, contributing to elevated efficiency capabilities in demanding motorsport environments.
