Mild steel Manifold?
 

Read all the faqs and tried searching to no avail.

I am VERY familiar with welding MIG (GMAW 85% argon)with mild steel. Currently our shop car holds the world record for Fastest and Quickest FWD 3S using a LARGE single turbo system I built from scratch.

But now I am taking that out and going to build a twin system so I need to make manifolds. I have 1/2" mild flanges already. I would rather use 16 gauge mild 2" tubing for ease of use/welding and cost then maybe get it coated. Is this adeqoute?

Nobody? :-\

www.honda-tech.com has a big welding/fabrication section. you could post there. but be wary.. everyone over there is critical. im gonna guess they will all tell u to use SS, but i've got a ramhorn thats made out of mild. its all sch40(idk how that relates in gauge sizing)

goodluck

it will work fine if you're having it coated. Ceramic coat it and call it a day.

Wholly Hell, a Ramhorm out of 40? That's gotta be heavy ;)
I have done the heat up and ben in a vice trick to get round pipe to match an oval flange port. Does this also work with schedule 40? I am worried about that since it's so thick.

Re:Mild steel Manifold?
 

Use schedule 10 Stainless.

I would but I don't want to have to get another tank, Currently I use 75% argon/25% carbon Dioxide mix for Mild steel GMAW.

Re:Mild steel Manifold?
 

You don't have to get another tank, that gas will still worke relatively well on SS.

i dropped it on a scale and it weighs 20lbs! the tubing was not oval bent at the flange so im going to get a stone V bit for my dreml and port it out.
