Motor mounts

[P944GUY]

Anybody found a good price on the Porsche (CORTECO) motor mounts...been putting this job off for awhile and finally have to get it done...I'm only putting in the CORTECO hydraulic mounts, I found them at Auto Parts at ********AZ - OEM Auto Parts - Discount Replacement Parts, Resources and Car Care Tips for $113 but they have been backordered for months so I have given up on waiting for them, Rocky Mountain European has them for $168 and Pelican are $198,

Let me know if you have found them cheaper else where..

Thanks...

[P944GUY]

Well I just looked again at ********az and they are back in stock..now $167 each.....I need cheaper people..come on!!!!!!!

[Vicious]

why only that brand? if your not stuck to that brand lindseyracing has 4 different kinds you can buy.

[P944GUY]

those are the original and best...dont wanna have to it again for another 10 years unlike a year or so witht he aftermarket cheap ones...

OEM s not always the same quality as OE... usually no difference, but sometimes there is. I've heard that the OE (Porsche branded) motor mounts are higher quality in this case (last longer). FYI.

Also, looking at the Pelican listing, the URO aftermarkets ($36) have a 24 month warranty, whereas the Corteco OEMs (almost $200) have only 12 months... go figure.

Personally, I'd probabaly either go URO or Porsche brand -- one extreme or the other.

No, actually, I'd think I'd go with these guys:

Pelican 951-375-042-04-SMA

Billet Aluminum Super Mounts

These Aluminum Super Mounts have elastomeric inserts that provides vibration isolation, along with superior operational longevity when compared to stock mounts. This engine mount system keeps the drivetrain located in the correct position with proper clearance, and allows you to put the power down where you want it most - at the rear wheels!

The Super Mounts are tried and tested on the street and track in 500+ HP monsters and stock configurations. They do not require shims and need no improvements to install on your vehicle. They are so confident that these high quality SuperMounts will be a permanent engine mount solution, that they offer a Lifetime Warranty that covers material and workmanship to the original customer.

$270 for a pair -- or only $135 each... with a lifetime guarantee! Sounds like a good deal to me...

Are those the Bill Haley shake, rattle and roll mounts? Where you feel absolutely every pothole, every jar in the road?

Only if somehow you've configured your car so the motor mounts take the place of your wheel suspension...

The job of the motor mounts is to dampen the transmission of vibration from the engine to the chassis. So you might feel more engine vibration transmitted from a more solid motor mount, but you aren't going to feel the potholes any more or less than with another mount.

[smokin_944]

Un-huh...A couple of hardcore P-guys that track their cars and frequent Rennlist ran them for, mebbe a couple of weeks and got rid of them for stock ones. I don't think they would agree. I am guessing you actually run a set or is this just speculation on your part? If you think they are good, mebbe you could buy one of their sets. I believe they wanted something like 20 cents on the dollar for them, lol...

Mark is right, motor mounts have nothing to do with feeling road conditions. Anyone who can't handle engine vibration from any motor mount in a track car is not "hard core". You can use solid mounts and no balance belt on a track car. These are comforts

MM replacement is not that difficult. I sure wouldn't shell out big bucks for OE mounts

[smokin_944]

The cars are dual use track and street. Lets review a basic fact. The 944 driveline has a certain amount of flex or float at the various connecting points: engine mounts, tranny mounts, and torque tube. Changing one point to eliminate flex without changing the rest is not neccessarily good for many reasons. As far as no balance belts, that is strictly for a masochist if it is being street driven in any way.

i had those supermounts in my car for about 10 minutes - very pretty, but WAY too much vibration transmitted - i yanked them right back out - when i did, i found that the all-thread rod was actually bent from the torque - turns out it is only grade 2 or something - very flexible

Mark's statement is still correct

Some may call them "hard core"
others may them "masochists"
a matter of perception perhaps

yes, one should use a solid tranny mount also...

We don't have a flex mount on the torque tube, unless you are talking about exhaust hangers, which are unrelated to this subject ...that has expanded from motor mounts.

i am pretty hard core - i have spherical bearings in every suspension location except the upper strut mount - i am very used to such things - i drove british sports cars for 30 years, so i am quite familiar with shimmies, shakes, jiggles, wiggles, buzzes and vibrations too

those mounts made me crazy - the whole car buzzed

maybe somebody else could handle it, and in a race car i wouldn't hesitate to do such a thing, but not in a street car

however, from a design standpoint, i could see that the all-thread was not going to last long under the torque load of the 968 engine - i am glad i removed those mounts, as i would have ultimately snapped one and been screwed

maybe a 944 engine would be better, as it has less mass, therefore less vibration to begin with, and with less torque it would put less stress on the all-thread

I'd like to get a closer look at those alum mounts sometime
perhaps there's some room to improve the design
(for a track car)

I don't disagree about street cars though
and even dual purpose cars - it's a challenge to find the right balance
I do prefer a little comfort on the city streets

[flash968]

lol - i find myself getting more and more that way as i get older

[944 boy]

I put the solid mounts in my track car. I'm going to check the balance belt alignment again. It shakes like crazy at a mid-low RPM load. High RPM it just buzzes. At idle its not that bad actually. But I would definitely discourage anyone to put these in a street car.

And I drove across country in said race-car with no heat/ventilation, sound deadening and with a broken OEM motor mount.

I did also put a solid tranny mount in as well.

Really? B/c I thought it was a beyotch....

[flash968]

at least on the 968, the driver side is a snap - 10 minutes tops - passenger side is a bit tougher, and of course the one that usually fails due to the heat
