Engine torque brace idea...

I am thinking about fabricating an engine torque BRACE. Not a dampner brace. But a solid torque brace. I already have patterns and ideas as to how to make it and all. What im wondering is, 1)how effective are these at actaully stopping your engine from torque twist? and 2) are there any potential drivetrain complications (i.e. breaking driveshafts, driveshaft yokes, anything on/in the rear end?) 3) would there be any interest in a solid torque brace at a cheaper price (50 to 60 dollars cheaper) than mainstream dampner braces?


Any ideas and info would be greatly appreciated!

i doubt they would create any problems bcuz companies already make them and you can always get solid motor mounts etc to stiff up the engine too...if they werent effective would ppl keep wasting money on them?

What are some companies that make a torque dampner? and how much should I expect to pay?

Oh, and not to threadjack, but where are you in OH, x Facedown x?

Torque braces tend to move the torque from the axis of rotation of the eccentric to the axis of rotation as if the pivot was vertical through the center of the engine. That is, instead of pushing and pulling up/down on the mounts, the engine tries to twist in the mounts. This will shear them.

Use solid mounts instead. It's not nearly as bad as everyone assumed. I was always against solid mounts until I spent a lot of time in a car that has them. Now I wouldn't have it any other way.

Would you advise against it for a daily driver? (solid mounts)

Solid mounts in a daily driver will be fine.

Bonzai sells solid mounts, but they are easy to make if you have access to a little bit of aluminum rod. Buy about 6" of aluminum rod with a diameter of about 2.5". Then measure the height of your stock mount and cut two pucks with a chop saw. Then drill a hole through the center.

I ran solid mounts in my T2 that I had. It was alright for DD, and after about a week you dont even notice the lil vibrations that the solid mounts give. I woud recomend them.

So if im reading this, and other posts correctly, the solid torque braces move the torque from the rotational axis of the eccentric shaft to the center of the engine thus causing the stock engine mounts to shear? If this is true, could it be remedied by using a combo of the solid mounts and solid torque brace? Or would a dampner style brace with the solid mounts be the better choice? Or maybe even ditching the torque brace all together and just going with the solid motor mounts?

Thanks for the feedback! And as always, every bit of info is greatly appreciated!

BTW MmSadda, Im located about 45 minutes southwest of you down in Huber Heights! Are you on the boards at www.ohiorotaries.com? If you are, whats your username? If not, check them out and sign up! Its a good site filled with good people. Anyways, its nice to meet a fellow rotard in ohio!

Beat me to it... solid mounts are the way to go.

I got my solid motor and tranny mounts from Banzai and the response increase is very noticable.

I also turned my rear differential mounts upside down and welded a plate across the front mount - effectively solid mounting the rear end.

Makes a little noise inside the cabin but its all music to me...
