Not too much of a stretch to say -- and this doesn't happen very often -- that Porsche got it from GM.

You also can try straps like ones on the hydraulic mounts in the picture.

I considered that too. My only concern was that the sheet metal might fatigue and break faster than a cable, considering the constant flexing. Maybe I'll try that if this one doesn't work out.

Otherwise it would be exactly the same, except made with sheet metal instead of cable. Not sure it that would make any difference in how it performs. It just needs to be able to restrain the mount from separation while not restricting it's movement or damping.

Just like the springs in your struts need constant replacement due do fatigue, right?

LOL - as if unibody sheet metal stampings and spring steel were the same thing.....

I like your idea a lot. Having used diesel mounts on a couple of my cars. They can be too rough and I've even had the drivers side diesel mount separate. So something like this would have prevented the driverside mount separation which then led to the engine and driveline getting a bit crooked. My shifter bracket was over to the right in the hole.

After putting ~4000 miles on my car going to Davis and back and other driving since this install, I think i can say I have around 5k miles on these mount cables.

Are they failing yet?

None of the issues that were presented can be determined by looking at them without taking them apart. Also 4000 miles is a barely a test.

It looks like the exhaust side crimp has failed?

How much HP are you pushing through them? Manual or automatic?

The geometry of those mounts just sucks. Too narrow - close to the crank centerline, they don't have as much leverage to work with against driveline torque. And angled backward - to balance against the trans mount pushing forward. It works with stock HP levels... barely.

If you use a ratchet strap you can keep squishy soft mounts on them, but all the added stress of a 1st gear turbo-assisted launch goes through the ratchet strap - which is located on the top of the engine, about as far from the crank centerline as possible under the hood.

Sorry. It's not my DD. I'll report back in 10 years
No it hasn't failed. Looks like new still.
Thanks, Dave

Just a bit more than stock HP. Maybe 200. 15 psi with a 15G, manual trans, G80, but I don't make a practice of clutch dumps very often.

Yes. The geometry sucks.

Someone with skills . . . make the mounts I really want (see post #20).

Skills = money, and the concept competes against a $5 harbor Fright ratchet strap.

Bose invented magnetorheological fluid and dampers. They sell a badass truck seat.

But of course they keep the mounts from sagging.

Instead of crimping the cables you could put those cable locks that use bolts and nuts perhaps.

I used an HFT ratchet strap and it kept breaking.. Rather just replace the engine mounts every year than deal with that or vibrations from harder mounts. I'm interested in seeing the verdict on those torque rod things in the group buy.

Those are going to be STIFF, not cushy at all like the hydraulic option Dave has pictured.

Dave,
Maybe could run the white block bolt in lower engine mounts I have and late 940 redblock upper mounts with the hydraulic cushions. Correct me if I'm wrong but the 960 whiteblock lower mounts are the same as the 940 redblock lowers?

Thanks, Jacob,
There might be room on the passenger side for something larger, but the 240 driver side is seriously crowded with the steering rack, which is much closer to the engine than in a 700/900. I know you have a 240, but the only way I see for a mount on the driver side that takes more space or moves outboard with a tilted motor would be putting it up on the frame like my image in post #20.

I suppose if I wanted to make the motor upright I could find a place for a larger mount on the driver side. But I'm not going that route in the planned future.

Edit: Here's a pic from a 240 Green Book showing how crowded that driver side mount is. No room.
