Engine mount - Suggestions?
 
Aw, Jeez...Here I've been planning on replacing my front engine mount when I did my water pump (which I now NEED to do), fully intending to use Pedro's Enthusiast's Mount when I did it. It sounded perfect for what I was looking for. Now I learn it's no longer offered.

Suggestions, I need suggestions on motor mounts. I'm not looking for rock hard racing mounts, but something maybe a bit firmer than OEM, with comparable or better longevity. (Like Pedro's Enthusiast's mount!)

What do you guys recommend?

go with the cayman mount. it is better than what we had, but still not rock hard.

or go solid

Just a note - the performance engine mount (in between stock and solid/racing) that I had installed does transmit more engine vibration than the stock mount. The add'l vibration is not bothersome but I can definitely notice the difference.

jhandy 06-28-2011 12:15 PM

Thstone is correct. I had a "enthusiast" mount. Semi- solid put on after my original craped out. The vibrations, for me at least, were unbearable.

I then installed the cayman mount which as the same durometer as OEM 986, but is said to be an upgrade on longevity. Now it feels nice- like from factory.

Thanks, guys. This thread is helpful, as I plan on doing this next month. Is the 987 mount any stiffer than the 986 piece, or is is just more durable. I would like stiffer, and am willing to put up with a little bit of vibration, but not much.

ekam 06-28-2011 12:23 PM

I don't think there's a difference between the boxster or cayman engine mount... since Cayman also uses the same 987 mount which replaces the older 986 mount.

987 Boxster and 987 Cayman use the same part. I could tell no difference between the 986 and 987 engine mounts in feel.

Why do you want a harder mount? Are you drag racing the car? You can always make your own mount, it's not hard.

Pat 06-28-2011 01:57 PM

Just for a more firm feel. I track the car a bit, and performance is a bigger priority than comfort.

JAAY 06-28-2011 02:21 PM

Be careful. The more solid mounts can trigger the knock sensor.

I just had mine replaced with OEM 987 from a factory 986 for a 2001 boxster and man alive what a difference!! I think it is a great combination of comfort and rigidity. From what I got from it. I only drove it about 10 blocks due a license discrepancy :( .

So far so good tho. I would recommend the OEM.

Also I don't track the car so I can't speak to that. But for street, she's a beaut!

... right!
Many people that have made their own or purchased a very rigid mount could end up loosing power,
The knock sensors on the engine are actually vibration sensors.
Sometimes with certain mounts the harmonics created can mimic knocking and the DME retards the timing, cutting back power.
Happy Boxstering,

This ******************************************** site is a scam. They stole the item photo and description directly from CHEETAH:

http://www.cheetahonline.com/products/c8036.html
http://www.cheetahonline.com/products/c8037.html

then they didn't reference who actually made them and raised the price. They have not been authorized to do this at all. I have also not sold them any mounts. I will be contacting them. Thanks for bringing it to my attention.

Now to the technical aspects. Both of these mounts were tested long term on my 02 S 6-speed (when it was still a 3.2 with stock transmission mounts). The Delrin definitely is stiffer and adds vibration to the car but serves a purpose. The Polyurethane / Aluminum one is what 99% of people want. I now have that with WEVO solid transmission mounts on my 3.4L swap and I love it. The stock mount is garbage and usually ends up ripping in half (as seen on the product pages).

I periodically scan during races / track days and have yet to see any knock from the mounts (and I have a more aggressive timing from the Softronic tune). Usually, false knock comes from metal contact, such as a something hitting the exhaust, etc. not vibration from the engine itself. They are made to look for certain criteria to activate (look-up vibration analysis).

Since I didn't remove any material I don't think it is much stiffer than the the original. It feels firm, but not too firm to me. If you do a search there are quite a few post about doing this on Hondas and such. I have a spare from an earlier replacement that I plan on filling and saving for a backup. For the price, if it lasts a year, it will be worth it to me.

You used window caulking for your engine mount, you used window caulking on your engine mount.

I have a WEVO with a modded 3.6. It is great for me, at first I thought it was too harsh but it loosened up over time and I got the squeaks fixed, one by one. I love it now.

When a mount say it is for track cars and racing they MEAN IT. In my case I would chew up stock mounts due to increased torque... just rip them into two pieces so I needed a more durable mount. If you drive on the road and run errands and track your car at one DE day per year then get the stock mount.

JAAY 06-29-2011 03:31 PM

Pedro. Learned that from you at Brbs. Waiting to get a cayman mount in. Mine is solid now. :cheers:

Not exactly, it is a polyurethane with a shore hardness of 55-60 when fully cured. I beleive this is somewhat softer than Delrin, and should outlast the stock material.
