Default Allow me to introduce you to:

The 92-99 solid front trans mount.


I'm sick and damn tired of ripping these suckers apart in less than 1000 miles.

isclaimer:

This is for the TOY car. Excess vibration and brutal forces to the differntial will be the end result if you try this. This mod is for the serious balls-out performance vehicle only. Test-fit and test-ride are at least 3 months away. This is just showing you the IDEA:

I have two spare front trans mounts here. One from Badnit, one from jr's3800. Badnit'* was in FAR better condition, so I used it to create the welding jig, as it was very obvious and easy to get it re-aligned. It'* important to start with a good template to make sure it'll bolt up to the car later.

After the jig was made, I stripped the rubber and epoxy out of jr's3800'* mount, cleaned it up, and custom cut the pieces I needed:

Note the clamps holding the mount in the 'OEM' configuration, and to the jig:

First piece welded on. It'* important to know the load axis and forces before selecting the areas to beef up:

Excess engine vibration will be the result of this, as well as an early differential death if proper precautions aren't taken. I have another idea for dampening out those vibrations with this uber-solid mount. That idea will come later.

Just thought I'd share the work so far.

Why would a solid mount kill your diff? I'm not following the line of thought here. Wouldn't it simply transmit more torque to the wheels?

Yes, I agree. The dampening is more for the luxury passenger isolation of vibration than the effect on the drivetrain.

Not sure why you kept the shock in place. :?

Nice modding Bill.

Come on now Wait for me. I want to play too

The first instantaneous torque on the drivetrain is absorbed by the 4 mounts. If you stiffen it up, that shock load is transmitted to the differential. It'* the weak point between the road and the engine.

Think of an electric motor attached to a fan blade with a plastic coupler. Start the fan with the blades stuck against the floor. What'* going to break? Simple. The weakest point in the system.

I kept the shock in place because there'* no point in removing it. It'* not in the way, and there'* still limited flex in the mount, and shock may assist resistance to that. FYI, I taped the shaft of the shock before painting.

Paul, I have another one to do this to if you want to play, or we can install this one.

Eeek. I guess there was no gas shielding?

You'd guess this is the prototype and I used my Arc welder.

The final version if this works will be made out of the other one, and a full-box wedge will replace the rubber.

Almost as bad as the welds on my exhaust!


Not bad for a prototype, Bill. I ought to do this someday.
