Torque Straps
Does anybody use or know of any products made to help reduce the strain on our engine mounts during a hard launch? Our engines produce so much torque, I'd like to do what I can to keep the headers from hitting the frame.

Re: Torque Straps (69rumble)
Solid engine mounts will work, but must be used in conjunction with solid tranny mount. Polyurethane mounts are almost as stiff, and should be used with a poly tranny mount as well. If you want to keep you original mounts, chassis component manufacturers like Chassis Engineering offer engine torque limiters. These are basically rods with threaded rod ends (Heim Joints) with brackets for welding to the frame and bolting to the engine. Since these provide a solid connection to the frame, they are very rigid and eliminate virtually all movement. As a side benefit, they will also result in more consistent reaction times, if you're into drag racing.

I remember a book mentioning chain. I think it was only on the drivers side and was left loose. This kept the engine isolated but restricted its movement.
Right near the engine mount. It may have used the bolts for the mounts, forgot.

Monty:
Is this true? All of my buddies are running solid motor mounts with a rubber tranny mount. They said that one of the problems with running a solid tranny mount along with solid motor mounts is that your tranny case will eventually crack(something has to give). I'm just curious because I'm planning on running solid motor mounts along with a rubber tranny mount.

Re: Torque Straps (bence13_33)
Solid motor mounts are obviously very rigid, second only to engine plates. They will allow for very little movement of the engine. It's generally recommended to run the same type/material or softer on the tranny than the engine. You definitely do not want to run a softer engine mount with a more rigid tranny mount. You would certainly run the risk of breaking the transmission tail housing.
