Should I use a poly engine mount?
Polyurethane (poly) bushings are commonly used to mount engines in vehicles for several reasons:
1. Vibration Isolation: Engines produce significant vibrations during operation. Poly bushings have excellent vibration-dampening properties, which help isolate the engine's vibrations from the vehicle's chassis. This reduces the transfer of engine vibrations to the rest of the vehicle, resulting in a smoother and more comfortable ride.
2. Improved Performance: Poly bushings offer superior stiffness compared to rubber bushings. This increased stiffness helps maintain better control over the engine's movement, especially during acceleration, deceleration, and cornering. It reduces engine movement, preventing excessive engine torque and movement that could negatively affect the vehicle's handling and performance.
3. Durability: Polyurethane is a durable material that can withstand harsh conditions, such as heat, oil, and chemicals. This makes poly bushings more resistant to wear and degradation compared to rubber bushings. They have a longer lifespan and can handle the stresses and strains experienced by engine mounts better.
4. Reduced Engine Movement: Engine movement can lead to undesirable effects, such as misalignment of engine components, excessive stress on exhaust systems, and decreased overall stability. Poly bushings limit engine movement and maintain proper alignment, ensuring optimal performance and reducing the risk of component damage or failure.
5. Customization: Poly bushings can be designed to provide specific characteristics based on the vehicle's requirements. Manufacturers can adjust the durometer (hardness) of the bushings to achieve the desired balance between comfort and performance. This allows for more customization options compared to rubber bushings, which typically have standardized characteristics.
Overall, poly bushings offer superior performance, durability, and customization options compared to traditional rubber bushings when it comes to mounting engines. They provide better vibration isolation, improved control, and reduced engine movement, resulting in enhanced vehicle performance, comfort, and longevity.
