Bad engine mount replaced... - 986 Forum - The Community for Porsche Boxster & Cayman Owners

sd_boxster -

what is your impression so far? you like the mount or think it's "too" much vibration? i guess I'm wondering if as soon as you got it installed did you think "OMFG" my car is going to shake apart..or was it just "hmmm...i can detect a little vibration in the steering wheel"....

i can live with "some" vibration. i know some cant....which may be "who" the enthusiast mount is for.

i'm tryhing to figure out if the racing mount would be so obnoxious that it really has no freakin business on a street car, or is it perfectly fine for an "enthusiast" who can live with some minor vibration.

i'm going to order one tomorrow.

The racing mount adds significant but not overwhelming vibration. It's most noticeable at about 3250ish RPM.

I do not mind it, but I'd be lying if I told you it is not noticeable.

No, it's definitely not an "OMFG my car's gonna shake apart" - but the vibration is transmitted via 4 chunky bolts into the body, so you definitely feel it, more through your butt than through the steering wheel.

I wonder if it tends to place more torque on the remaining mounts with the potential to cause premature failure?

i'm confused, does the Pedro mount ONLY include the little center rubber thing and you press it into yhour existing mount...or does he send you a whole new mount/bracket and you just swap them in/out? from the photo SD-boxster uploaded, it looks like he was pressing out the center piece....

when i looked at Pedro's page, I got the impression he was sending a bracket with the mount alrady installed into the bracket itself. you just unbolt hte one you have, and then bolt in the new one.... is that how it goes?

i'm right now torn between whether i do the enthusiast mount, or go for the new "upgraded" 987/cayman mount. not sure which is ultimately "better"?

i don't mind some vibration if there is a benefit to it, but i don't want to get vibration just to have vibration. some people have reported doing the cayman mount and also being very very happy with the result, and I don't beleive it results in any vibration at all...but maybe the end result is "not as good" as the Pedro mount in terms of improved shifting.

is there any improvement in overall "handling" feel of the car...like when you turn or corner, does the car feel more solid / rigid with this new Pedro mount? I did an engine mount on a prior car (which was also broken) and the result was firmer steering feel...as well as better shifting

just wondering what the results really will be...and what is the best mount to pick

When I replaced mine, I'm pretty sure Suncoast said there is only the Cayman mount now, period. The rubber has been redesigned but what I thought was cool was all the triagular cutouts in the aluminum to reduce part weight even more...

thanks.

i'm on the fence between the cayman mount and the Pedro mount. Pedro's is cheaper. I could go with his enthusiast mount, and not get much vibration....

then I get the fun job of trying to explain to my wife why the car went into the shop for a water pump and will come out with a water pump, an engine mount, and maybe a techno brace....

Received mine yesterday, it is the entire bracket. The lower price for "core only" applies if you send in your old mount to be "reconditioned" and converted to the racing or enthusiast mount. I bought the entire assembly since the cost of shipping between Australia and the U.S. for me to return the bracket was cost prohibitive.

I hope this helps.

i asked my mechanic to take a look at my engine mount while he had it in the shop to do my water pump. he told me it looked like it was worn and may have initial signs of cracks, but he said when he seems them "fail" he notices a clunk when he shifts or takes off from a stop...something like that... he said I had no clunking and he basically said he'd be happy to change it for me, but if it were his car, he'd probably just leave it....

my car has 75k miles. is it possible that a car with my mileage still has "good" mount or are they virtually ALL bad by my mileage???? i was under the impression that by my mileage, ikt would be toast...

my car had a new motor put in at 15k and the car has 75k...so my mount likely h as about 60k on it as he stated these get changed if the motor gets replaced...

... first, if you have an OEM mount, they only last 45,000 miles.
If your mileage is beyond that, I guarantee it is cracked.

The 987/Cayman mount is much softer than the older 986 mount. Some customers complained about the 3000 RPM vibration and Porsche removed even more material and made the material even softer. They now only last 35,000 miles.

Most people find the Enthusiast's Version their choice, even if they AX and DE.
The Racing Version I only recommend for a track car. The vibrations are very noticeable. I'd only recommend it for a dedicated track car.
The Racing version also provides less power loss to the rear wheels.
Both versions provide much better shifting.

When it's brutally cold (below 20F) the remanufactured mounts will transmit much more vibrations for the first 10 minutes or so, until the engine's temperature warms up the synthetic rubber compound and makes it more flexible. In warmer climates, it's a non issue.

The TechnoMount is supplied as a bolt-in piece, complete bracket, not just the center.

The TechnoMount will not harm the transmission mounts which are gel-filled.

Hope this helps.

Happy Boxstering,
Pedro
