A crank pulley cover, also known as a harmonic balancer cover, is a component that can be added to the Honda / Acura NSX engine to serve several purposes:
- Aesthetics: The crank pulley cover can be used to enhance the appearance of the engine bay. Some aftermarket covers are available in different colors, materials, and designs, which can give the engine bay a more custom and sporty look.
- Protection: The cover provides protection to the harmonic balancer and the crankshaft pulley from dust, dirt, and other debris. This can help to prevent damage to these components and prolong their life.
- Weight reduction: Some aftermarket crank pulley covers are made from lightweight materials such as aluminum or carbon fiber, which can help to reduce the overall weight of the vehicle and improve performance.
- Performance: Some aftermarket crank pulley covers are designed to improve engine performance by reducing the rotational mass of the crankshaft, which can help to increase horsepower and torque.
- Improved grip: Some aftermarket pulley covers are designed to improve the grip of the crankshaft pulley, which can help to prevent slipping of the belt and improve the overall performance of the vehicle.
It’s important to note that some aftermarket crank pulley covers may require modification of the engine or other components, and that it’s always recommended to consult with a professional mechanic or an experienced technician to determine if it’s the right option for your specific engine, and to ensure proper installation and function.
