Depending on your vehicle, horsepower, and engine mount brand, the amount of vibration can vary. Polyurethane will allow more vibration than rubber mounts because of its increased stiffness. This allows more energy to be transferred back through the driveline. Rubber mounts are ideal for stock or mildly modified street engines, but as horsepower is increased, it may be time to upgrade.Ĭompanies like Energy Suspension and Prothaneoffer polyurethane engine mounts that provide a compromise between rubber and rigid solid mounts. The harder properties of the polyurethane hold the engine in place better than spongier rubber. This means less power is transferred from the engine through the driveline and into the rear wheels. They can be prone to cracking and tearing after a while, and also allow the most movement under load. Rubber engine mounts, like the ones provided by the factory, offer the greatest vibration and noise dampening effect. However, there are a few drawbacks to the old rubber-style mounts. Quite simply, there is a give and take between engine mount materials, and choosing the right mount often comes down to your intended vehicle use. That’s because the right choice can come down to your personal feelings about how much vibration is too much…or how much power loss at the wheels is too much. If you look at any forum discussion on motor mounts, you’ll notice that opinions vary widely on what makes the best engine mount materials. All motor mounts are designed to allow some flex or movement, but too much engine movement can lead to strain on your driveline and even prevent normal clutch and transmission operation. Signs of a bad engine mount often include more noticeable vibration inside the vehicle, increased engine noise, or excessive engine movement. They typically attach your engine to three or four points on your vehicle’s frame or subframe. An engine mount’s job description also includes absorbing engine noise and vibration and preventing misalignment between driveline components under high loads.Īs you can see, motor mounts perform some very important tasks, yet they rarely get any attention for their work. It’s a dirty, thankless job, but someone (or something) has to do it.ĭeep down in the abyss of your engine bay, engine mountsare tasked with the tough job of holding your engine in place.
