Im working on a rear mount turbo set up and was wondering what your thoughts were on using mild steel for the charge pipe. The reason I want to use it is because I can weld it up no problem. If I use aluminum then I have to try to fabricate the charge pipe and take it somewhere to be welded. My concern with the still is rust in the charge pipe.

ive run mild steel charge piping and never liked the way it came out. I just switched to aluminum and am very happy. Im able to bead roll the ends and polish the piping.

What are you using to weld the charge pipes now? Mig?

Yeah just a wire feed mig. I hear you can set them up to weld aluminum. With the mild steel charge pipe did you see any signs of rust?

Mine came as mild steel, but I painted them to prevent rust.

I tried setting up my MIG welder to do aluminum, comes out like ****.

I live in cali away from the ocean so rust isnt an issue. I was thinking about rust on the inside of the charge pipe. But it sounds like people arent getting any moister on there

You can just do aluminum bends and straight sections and join it together with silicone couplers.

I would recommend doing this as well. You could also plot out your pipes and have a shop weld them up for you. Aluminum will save weight and dissipate heat faster.

Yeah I think the aluminum with the couplers is my best bet. Thanks guys

yeah you having a butt blower and wanting to run your up pipe in mild steel is gonna weigh right around a metric fkk ton.

if you dont want rust, just use stainless.

Although you could get the mild steel pipe coated or plated somehow to prevent rust. But by time you messed about doing that, you could have done it in stainless or alloy in the first place.

Butt Blower HA HA HA.

just use stainless steel if its that big of a worry.

Or shoot me a call and I can have an aluminum one shipped out by weeks end

Your aluminum charge piping will be shredded, crushed, and/or ripped out on your first speed bump.

About 25 pounds, tops. Same weight as single exhaust pipe of same length, and worth it...Also, not quite a metric ton.

Run stainless or mild steel (coated) from rear to A-Arm, then you can go to Aluminum once you're forward of the lower A-Arm. Trust me.

If you go mild steel, after welding, you can coat it yourself for $38.95 : http://www.kbs-coatings.com/cycle-tank-sealer-kit.html

absolutely nothing wrong with a steel charge pipe.

Ok I would like to use the steel because its easy to work with. Thanks for the input guys

when I built mine, that came nowhere near close to 25 pounds, tops.



remember to account for hot side all the way to the back (lets call it the factory weight) then all the way back up to the front again....

HRHohio

Well, I wasn't counting the hotside (Factory weight as you call it), considering you need that regardless if you're front mount or rear. I use my stock manifolds, y-pipe, I pipe, over the axle. Oh, cut the 10 pound muffler off to put the turbo on, so there's net 10 gain.

Then again, I thought we were talking about the charge pipe, not the whole system. I'm standing by my estimated 25 pounds net added weight for the charge pipe. Slightly less than a metric ton.

(Nice looking setup by the way)

I'm just thinking ahead, people spend a lot of money buying light weight car parts, why not upgrade to aluminum since your at that fork in the road already and save in the future.

I know I'm going to do aluminum a few feet past the DP to save weight running it to the back.

Thanks, I built that like 6 years ago. I'm currently stocking up on metals for the new build.

that section i posted up came in around 40 pounds and it was dumped right before the axle. I cant remember what gauge it was but i built it with spare pipes i had from my hotside so maybe 16?

Either ways OP, if this is your first build try not to rush it. Think deeper into the future when you have to start adding weight for safety gear. Cage here, SFC's there starts adding up

HRHohio

Yeah, weight sucks. I weighed in at 3950 lbs with me in it the other night at the track.

guys you are thinking too hard. if weight or performance was a concern the turbo would be up front
