The question itself inculpate that there ’s some heavy secret to be extracted from simple ironware pieces . Motor mounts are plainly wall bracket , mostly metallic element , that seize to the engine on one destruction and the car ’s locomotive bay on the other . They ’re contrive to keep the engine in office . Though motor saddle horse vary greatly in appearing to accommodate different locomotive engine layouts , they ’re all similar in anatomical structure . They ’re usually brand or another laborious metal with plastic or rubber padding . If it ’s really comfortable to improve motor mounts , you might ask , why do n’t auto manufacturer do this themselves ? It ’s a reasonable query . The truth is , motor mounts are designed to appeal to the broadest part of the universe – that is , people who do n’t need to think about them . People who want the engine ’s vibrations and wiggle around to be downplay as much as possible so they do n’t have to see it , experience it , or worry about it . Let ’s face it , that ’s most masses – this affirmation ’s backed up by the fact that most cars sold are of the non - performance variety . And in that respect , factory locomotive engine mounts do their job quite well . But to do that , they have to be quite flaccid , like small shock absorber absorbing the impact between the engine and the car ’s frame , so the people in the cabin can barely feel what ’s going on up front .
The result of this is what functioning tuning companies call drive communication channel thong [ source : Anthony Woodford Racing ] . This means that when you run into the gas to speed up and the engine bring forth the torsion it needs to move forrard , some of that torque is turn a loss . The soft engine mounts immerse it as the railway locomotive shifts around , because that additional movement would do uncomfortable ace in the car ’s cabin . But if that wasted torsion could or else bypass the cushions and move down the drivetrain to the wheels , it would result in the car lay more power directly to the undercoat . For some drivers , that increase in world power is worth sacrifice a fiddling comfort .
The locomotive still needs motor saddle horse , of course of study – and so , there ’s no way to completely excrete drive line lash . The points of middleman between the locomotive engine and the railcar do demand some protection ; however , eager drivers have the option of upgrading to performance motor mounts . They ’re made of stiffer material than the factory originalrubberparts – ordinarily a heavy urethane material that absorb less palpitation and therefore , absorb less power , too . Upgrading might be an specially attractive option after the stock parts wear out . mill original mounts last a pretty farsighted time , but engine oil colour leak are a common movement of premature degrading . Worn mounts will allow a running railway locomotive to shift and leap in all kinds of unpredictable , might - sapping way .
There ’s no way to watch how performance motor mounts will affect the comfort of your ride . Some summercater tune up companies offer their mount in different grade , from a hardly - noticeable change to a much firmer and rough experience that might be best left for a weekend track toy . And , of track , the end result and monetary value also depend on the specific make and model of car . Since you have to remove the elevator car ’s engine ( in some cases ) , upgrading motor mount can be a ambitious projection to take on in the garage , and one that require a passel of specialised equipment , too [ rootage : Popular Mechanics ] . A honorable aftermarket tuning shop , however , will be able to suffice your comfort concerns before you get started .

People have used hockey pucks as motor mounts . It ’s true . I ’ve seen it . It ’s not really recommended , but about 10 years or so ago , when I was on a regular basis hang out with a group of guys who performed engine swaps , it was considered an inexpensive way to get a high - execution mount . Metal brackets were not considered necessary .
Hockey pucks are made of hard pencil eraser that ’s very interchangeable to an locomotive engine climb . I ’m not advocate it , and HowStuffWorks.com certainly is not recommending it . But it was the first time I ’d reckon the conception of " performance " engine climb . And I guess the mellow - end polyurethane mount useable at the time just were n’t good enough . Or perhaps they were too expensive . In fact , there were plenty of things in our earthly concern that were too expensive at that time … like any car less than 15 eld old . The boy buy hockey pucks in bulk . I did n’t . My car rattled enough as it was .
