That'* quite a piece of engineering, even when it was in stock form. Can't say my E-body has any mount that looks like that

Looks good Bill, glad you mentioned how you are only designing for the track.

In the case of mine, the strut on it, there is much more limiting than 25%. Without the strut the 94-99 mount is the same as your 92-93 mount. With that strut removed, my mount survived about 7 miles. With that in mind, removing the strut and making a solid link there while maintaining the rubber wedge is working great. It reduces the amount of vibration that the direct connection causes when at rest/idle.

To date my rubber wedge has not broken free from the remainder of the mount.

Boosty makes a good point. Those welds will be very brittle unless properly annealed and very prone to stress cracking with the kind of torque that Bill'* engine is producing.
Time will tell, but it might better to simply remove the shock and replace it with a solid (hard rubber) spacer.

(Repeating myself)

This is not the only part of the solution. You haven't seen the vibration damping yet.

I understand your desire for something that won't tear in record time. I went through two mounts w/o the strut in record time, then bought the third to make that new mount. The most interesting things that came out of it were from conversations with Bill W, I considered going to the 92-93 mount. (at that time he wasn't ripping them to shreds) And In looking at how my new mount reacts under stress the rubber wedge doesn't appear to be factoring in as a major point.

It will be interesting to see how you plan on dampening this new mount as it typically bolts to the trans and subframe directly. Looking forward to part two of the thread.

I was wondering how and when someone would make a mount for you pre-00 guys. Def a lil more engineerin involved for these cars than throwing pucks in... looking good willwren!!!

Done and installed (Sorry, Bullet, but there'* plenty more to play with).

WARNING. You better make damn sure you've got it aligned well before welding. Road test was a grinner. INSTANT throttle response off the line without the drivetrain flexing. I can FEEL the engine vibration through the steery wheel and the go-fast pedal. Not bad, but I know it'* there.

I should be able to dampen about half that out with a little magic. Won't be tomorrow, I have a radiator to replace in a Toyota tomorrow.

Again, favorable results, but much more abuse on the diff. This is for the well-built trans ONLY. And it'* not done yet.

What is your idea for vibration dampening?

I have the setup with 8.5in x 0.5in. bolt with rubber washers at the bottom. I have rubber washers On either side of the frame, and one on either side of the tans mount part. And at the end a lock washer and double nuts ( not trying to be funny) at the top.

I love the car when it pulls. But sometimes the vibration in the engine is noisy when I shift into over drive and it resonates through the steering wheel a little.

Although your mount is quite different than mine (because the 92-99 also has a torque-axis mount over by the water pump), my vibration damping idea may help you a little.

Stay tuned. I'll show you when I get it done. Very busy at work right now. Should wrap this up sometime this week.

Dual-layer eleastomeric damping material. This will damp the vibration without allowing flex.

I didn't have time to let the laser finish the cuts, so I let the shallow cuts be my guide. They would have finished, but Paul was at my house drinking my beer, so I had to jet out of there. We'll install these tomorrow if we don't have hangovers.
