Do you guys think this is possible ?

I'm going to making a header for a turbo on my car, I'll be using 304 stainless tube ( 16gauge ) and wanted to know if a 20lb turbo would break this material. The turbo would be braced but I'm having some doubts, here is a pic to get an idea



With a brace like this

I wouldn't recommend using the header to support the weight of the Turbo. Every turbo car that I ever worked on always had bracing from the turbo to the engine block. That including cars that used cast iron exhaust manifolds. If you are just making 1320 passes then you might be able to get away with it but if this is a street car, the stress and vibration from everyday driving will eventually cause something to break.

I have no clue but those are great pictures

[garth]

not much of a clue here either I would try the ask andy part of the board. good luck. garth

What kind of camera

I'm like monte..great pics! What kind of camera did you use?
I don't really know what to say about the bracing other than looks good to me ..but i'm no expert and I own a MM250X what does that tell you *LOL* I guess I need to quit poking fun at the 250x before i get kicked off here..maybe they will exchange with me(210 or 251) and let me pay them a little boot.

support for your turbo

Can you go to a heaver material like 10 gauge and 316 stainless? I'm
sure this would do it, All depends on how you design it.

They don't sell mandrel bends in that size

If they dont sell mandrel bends in that size; What you can do is get a straight piece and make your own 90 degree bend quit easy.Mind you what I have in mind will take a little time.On the straight piece start out cutting your first two pieces at 12.5 could also be 7.5 degrees I dont know what size of tubing you are using (But it looks like 3") on the second piece turn it 180 degrees and continue that untill you start to see a 90 deg start to appear. I dont know what kind of penatration you are looking for but if you are looking for 100%
dont forget to use an Argon backing gas.
I hope this helps ya. If you have any trouble there is an inter-net site
called steel template development it should help you with your 90 degree bend if you what to go that route.I do have another answer if what I said here doesn't help. take care

Time is money, plus when you go down to that thick of gauge, cutting becomes an issue. Tubing is 1.75 o.d

I guess I need input from more guys building what I'm going to build, no offense but I know a lot of racers do use this material but I just wanted feedback from people that knew more about this area.

It is never a good idea to have the header tubes support the turbo, as the tubes are subject to heat cycles and vibration, both of which like to make things crack. I would just make a bracket to support the weight of the turbo, using material similar to your braces, but support it from 3 or 4 directions. Use mounting hardware that will allow some movement from expansion/contraction and vibration, without making the header tubes actually support the weight.

sorry I could'nt help well I tried eh

Multiple welds in headers are "cool" so keep in mind that you can always use fittings for the el section. As far as 16ga, it might be the best thickness to use due to expansion/contraction issues. Thicker gauges will be stronger but won't "give".

If you have the ability to make it, you will have the ability to repair it if it breaks...but I'd still put some support on it.

I don't know why somebody thinks they need 4" exhaust on a 4cylinder engine. All they will be doing is slowing down the exhaust flow and getting the downpipe and engine bay a lot hotter than otherwise.
