a friend of mine is gonna make a turbo mani for me, so i went and bought the piping for it but he says he thinks it's too thin ( looks a lil bigger then 1/8th thick) so how thick should the piping be to hold up to the high temp.????

 

Sch 10, and 40 seem to stand up to most abuse. Of course there are hundreds of other factors, that will determine the durability of a manifold.

Here are the measurements of both schedules:

1.5" s/10 = 1.9" OD x .109" wall = 1.682" ID
1.5" s/40 = 1.9" OD x .145" wall = 1.610" ID

 

my current manifold is schedule 10 304ss. my new manifold is going to be 16guage ms.

 

16ga on mine... You need to have a mount/brace for your turbo so you dont put any weight on the manifold.

Why are you going from ss to ms?

 

I'm sorry to bring an old post from the dead, but would 14ga MS pipes work too? And what knd of brace are you talking bout?

 

would 16ga not hold the weight on itself without any brace/brackets...

It might support the weight of the turbo when you build it, but once you get it hot it will have a tendancy to crack.

good question.

I wouldnt really use them but I suppose you could. Mild steel is not going to hold up to the extreme heat as well as stainless so it might have a shorter life span than expected. The braces mentioned are built to support the entire weight of the turbo so the manifold is bearing little to no weight.

 

Ok, so if I build a MD mani, how would you brace it up to keep from cracking?

 

If I make an MS mani, what kind of brace/bracket would I need? And pics for an example?

 

 

What about on a Honda application? Seems like too much trouble....

 

Same priciple.

Spend a few hours now in the preliminary design phase to account for possible future problems, or spend MANY more hours developing a new manifold when this one cracks due to stress ... it's your call.

 

What about making a bracket off the ms exhaust flange to the turbo flange?? That seem like it would work...

ever seen an ssautoshitmanifold? Doesnt seem to work to well. triangles own you.

No man...I'm not talking about sheet metal, I'm talking those bar looking things as in the following pics...

it is going to be ceramic coated so i want to keep it all the same material. ms is also cheaper. 16g has a side wall thickness of .063"

Oh man I'm confused about what you are talking about now......I was talking about the bar welded between the turbo and head flanges on a ssatuoshit. Bracing to the body of the turbo would be better.

 

The exhaust and turbo flanges will be .5" thick....I was seeing if you can make a bar to hold these two flanges together in a certain way so they can support the weight of the turbo so I can get away with MS 16ga pipes and flange.
