High HP and Engine Mounts
I am just curious if any of you high hp and high torque guys have ever broken any engine mounts and if you have any cures. I have ripped 2 left side motor mounts in half in the last 3 months. I am thinking of using a old school method of using a cable to limit the movement to prevent the mount from breaking.

I believe it's how torque tube ties engine and trans/diff together that helps unload some of the torsional stresses in C5/6.

Not sure if these would work in your application.
I bought these and tranny mount to try and keep things together.

I guess when more people try Yank 4L80 conversion in which torque tube is allowed to twist making it comparable to conventional or engine mounted trans layout, we may see more motor mount issues or failures.

Loboost....
My car is a DIY LS1 conversion.
Ive always had my engine bolted in solid. Really...you would be surprised. I wouldnt have it any other way. I dont drive it daily...but would have no problems in doing so. I certainly wouldnt say noise or vibration is a problem at all, and I can be fussy.
Now as for my rear axle/rose joints...thats a different story !

The connectors are filled will poly and absorb the vibrations.
Here's the rear connector.

Thanks guys for the info it helps a lot I think I will just go ahead however and use a cable to limit movement I really dont want any engine vibration at all. I feel the poly while being a good compromise will still transmit more vibration than I would like.

Is there any way you could get a drive in a car with poly mounts ?
IMO, the first time I mounted an engine in solid, I was amazed ( twin turbo Rover V8 in same car )
It was by far one of the best things I ever did to the car. I couldnt even tell the difference. And the LS1 is even smoother.
