16ga. for turbo mani?
Just as the title asks:
Is 16ga. strong enough to be used for a turbo manifold? This will be holding a relatively large turbo. I searched but couldn't find a straight answer. Thanks in advance--

Re: 16ga. for turbo mani? (rkeith)
For a turbo manifold I wouldn't work with anything less then schedule 10. Roughly .109 wall thickness on a 1.5" fitting. Easy math but 1/16 has a wall thickness of .0625
16ga has and will work...the manifolds I've seen in person made from 16ga do not hold up.

More the likely they are not fabricated correctly and are requiring a thin piece of tubing thats constantly being heat cycled to hold a very large amount of weight.
16ga is probably more then adequate and will do what it's supposed to flow the exhaust gases to the turbo however it is not supposed to be used to support the weight of the turbo this is not the headers job

Re: 16ga. for turbo mani? (Casey@Burns)
Oh hell yes the great thin-walled tubing vs. plumbing pipe manifold thread is back again. Not to be a dick, but this comes up all the time. Half the people on here are going to say "you can run 16ga. tubing if you brace the turbo, which is the proper way to go." The other half are going to say "OMGWTFBBQ all my friends 16ga. manifolds cracked because it couldn't support the turbo. Make it out of 40 lbs of plumbing pipe thats the only way to go." So in the end its really your choice. The latter is less work in my opinion, which is why people tend to go that way.

I would not disagree with any part of this...the people that made the manifolds I've seen/used had less than a good idea of what they were doing. Unfortunately even after supports were added there were still failures. I would have been interested to see the results had they made the same manifolds using sch40 or even sch10 fittings.

Re: 16ga. for turbo mani? (Keyhole)
I thought 16ga. would be alittle too thin but I have heard of people using it, which is why I asked. I'll be using alot heavier gauge tubing for the peace of mind knowing it will hold the weight of the turbo without needing alot of bracing and whatnot.

Re: 16ga. for turbo mani? (rkeith)
Has anyone found any of this useable 16ga tubing at places like Home Depot or anything? I need to make a couple manifolds and I need a source for the tubing (simple log style or simple runner manifolds). I have fabricated surge tanks, intercoolers and other things, but have yet to make manifolds.
Any help is appreciated.

Personally, I'd rather work with tubing. You don't need to bevel it or weld in multiple passes. It grinds and cuts faster also.

I don't think Home Depot has what your looking for but i'm sure we do if your looking for stainless that is. http://www.burnsstainless.com

Not everybody is a welding god like you though.

All I've seen at Home Depot is conduit. Unless you want to make a copper exhaust manifold.

Re: 16ga. for turbo mani? (daveG)
Well, I have only TIG'd mild steel and aluminum, never stainless yet. I assume though if I can weld mild and aluminum I should be fine. I was just thinking in terms of keeping costs down to make some simple turbo manifolds for the locals.
What thickness of stainless is generally acceptable for a streetable turbo manifold that is simple in design as well?

A lot of people use Sch.40 bends if you don't want to have to brace them.

Re: 16ga. for turbo mani? (daveG)
Properly braced 16ga will work fine. Using a brace similar to this:
The heim joint setup allows the manifold to move the turbo around as the material expands when it gets hot, but still supports the weight of the turbo. Notice the brace on the wastegate as well on the first picture.

Is there any downsides to using sch. 40? Is there a "thresh hold" , if you will, of weight that an exhaust flange can support? The whole bracing thing to me makes since to me regardless of if you use sch. 40 or not, but maybe im wrong? What things can go wrong if you use sch. 40 with out supporting the setup? I know that theres pros and cons to this....maybe someone can enlighten me.

You could brace a sch. 40 manifold, but it'd more than likely be overkill as its been shown that they can support the weight of a turbo.
