Seeing as the Evo 9 has a similar engine (shape)to ours has anyone measured or fitted up Evo9 engine mounts to our cars to see if they will work...

 

Even if they do fit, they're probably not worth it. For the price of a set of new Evo9 mounts, you could buy a set of RRM solid mounts (or make your own) and have plenty of beer money left for the day of installation.

 

I am not sure as to how much a set would be but I suppose I was just more curious that if an Evo puts out xxxhp you would think that the mounts would be quite strong and still be very driveable with very little vibration thru the car vs solid engine mounts... I had a bad experience with some solid mounts so I am very weary of them as to how good they really are...

 

Funny, I just got back in after installing a solid mount a friend made for me out of 75A polyurethane. A bit squishier than RRM's mounts, and a whole lot softer than the mounts I made a while back. Haven't taken a test drive yet, but I did start the car up, and it didn't sound like my dashboard was going to fall off like it did with my old mounts.

 

Here you go. This might help you out with your question?

^ Ralliart50 Thanks for that I did not see that post... ok so the factory stock Evo mounts will fit up... excellent now just need to find out what sort of vibrations they cause although you would not think there would not be any...

Myszkewicz- the vibrations go away when you hit over 60klm hour but at slow carpark speed and even at idle can get a bit severe like I said the last time I put solid mounts on my car it stuffed up the head unit in the car and became unbearable so I bought new set of mounts - Factory and left it at that... the engine dampener is the other alternative to help prevent or just to slow down the movement and hopefully that will increase the life span of the stock engine mounts

 

the damper helped alot but im not putting out the numbers you are.

I recently got the RRM motor mounts and they were almost violent at a light for a 100 or so miles but they broke in and are good now. def. for the money should have gone straight to the mounts as per i can feel a difference. so for your car i wouldnt even consider damper.

 

Remember, the info in that post is for a mount INSERT, not a full mount. The front motor mount from an Evo will probably work (I think all Lancers are the same) but the rear mounts are what's different.

 

so if motor mounts work alot better than the engine damper to eliminate wheel hop, theres no real point in getting the damper right? and what do u mean by "violent"?

 

If you get good solid mounts then there's no reason for the damper. However, the damper is an excellent option for people who don't want extra vibration and want an easier install. By violent he means excessive vibration.

 

sorry dont know too much about them and its probably something i will get in the future. where would the vibration be coming from? i thought the motor mounts were suppose to stop the engine from vibrating?

 

The engine mounts are to reduce the amount of engine movement or slow it down (this is why solid mounts are used) but the downside is that no matter how much you bolt that engine down to stop it moving it will still move.... but instead of it being long movements it is now shorter sharper movements meaning that the vibrations and movement are not being absorbed into a soft surface so the vibrations are now felt thru the car... simple thing to try out you have a golf ball and drop it onto a soft surface.... say compacted sand - result is the sand will absorb the ball and it will not bounce... now drop the same golf ball onto a much denser surface say wood (ony mention wood because it is still a fiberous object that closely resembles the way a engine mount material is made from due to the grain... probably confusing people here) anyway drop it and it will bounce some - the wood is not able to absorb all of the movement of the ball

Trying to find a middle ground were we can reduce the amount of movement in the engine and thus reducing wheel hop and any other not so nice side effects but also making the car very driveable at low speeds - so basicly you still want some movement but not so much that it reduces the hp that the car has or the driveability comfort but reduce the movement too much and you have a very coarse driving car which may not be comfortabale all the time... this is why I am wondering if a major benifit can be found in the Evo stock motor mounts as these cars have similar engine shapes they face the right way but just have more power - so in theory the EVO m/m's should be perfect for our cars and still make for a very comfortable ride

I hope that explains it ok I may be wrong but that is how I see it..

 

Please also remember that they were only violent for about a hundred or so miles, the vibration decreased significantly now but is still their. i think the little vibration is well worth it.

 

Well, I put this one in yesterday, and while there is a little more cabin vibration, it's not bad at all.

 

I've got the RRM mounts and there is, at least imo, little to no vibration change from stock. At idle you can feel the vibrations in the steering wheel but it didn't make the car too much louder. While at anything more than an idle speed you can't even notice. I am not sure why you are so afraid of the mounts, my car squeaked and rattled more the first winter than it did all summer with the mounts. If you go with the damper with your power you are asking for trouble, good mounts are an important part of building lots of power.

For example my buddy with a Civic EX has torn one stock mount up in less than 100k of driving on it, and he puts down less than 130hp with his mods and an aftermarket clutch/flywheel combo (more stress on engine and drivetrain due to faster and harder shifts.)

Either go with solid mounts or watch them closely. As a matter of fact I have some stock mounts for sale in my sig, you should buy them and either make your own or have some for when you tear yours up.
