Turbo Bracing Question:

[tpunx99GSX]

Wouldnt making braces and attaching them to the motor create more Vibration? being that the motor viberates so much. it would almost be better to create a brace around the turbo that would connect to the manifold above the bolts that connect them now. that would take the stress off of the area that the turbo bolts onto on the manifold.

The turbo is connected to the manifold which is connected to the head which is connected to the block, there is no flexable material anywhere in there that would isolate vibration. Supporting the turbo off the block is the right move. The downpipe can be supported as well, but bracing the turbo to an unsupported downpipe makes no sense at all, it would if anything, add more weight to be suspended from the manifold you are trying to keep from cracking.

I totally agree with mike. Support it to the front of the block somewhere. Even with the turbo braced, it will probably still crack, but it won't be quite as critical and it will probably take longer to crack.

Then shouldnt the question be, How do i support my manifold? Like fabricating a Brace that will add more support under the manifold. Kind of like a Shelf type brace.

[Raptor]

No, alleviate the weight suspended from the manifold and you will solve a lot of the problems. Trying to rig up some shell to make the manifold stronger is only a large complicated mess which would be unsuccessful anyway and take 5 times as long to do. Support the turbo from the front of the block, why is that so hard to understand Tom? The answer is somewhat simple in this case as is the problem. Not something to try overengineering.

Mike is right, just fabricate a brace that runs to the front of the block, done deal.

Alright then. Thanks for your help guys :)

[JET]

One thing to remember, make the brace from the same material as the manifold. That way your expansion rates are the same. If you make it from a different material, then it is going to expand differently and may actually cause stress on the manifold.

If you weld a small 1 inch or so tube in the right location, it lowers the vibration considerably on the steel support. I work with these kinds of things at work. I aint fuckin around ;)
