Just used mild steel on my turbo build, it’ll be fine for what I am using the truck for!

Hey dude, don’t call yourself an idiot because there is people out there would love to do what you’re doing and have no clue how to you’re helping a lot of people. Thank you for doing what you do.

[@dannyabeauchamp4881]

@me for this! I’ve owned the materials and the hardware for my turbo kit but have been to scared to mess with it. But this video gave me some nice info and ideas

[@Typical_Garage]

It all looks the same once it's covered with heat wrap 😉

[@ronaldrey8474]

The rust on the inside sucks in the engine and destroys it Not about the outside look but I agree heat wrap covers the outside and outside shiny stuff is shallow.

[@Typical_Garage]

@ronaldrey8474 Are you under the impression that exhaust gases are fed into the throttle body?

[@THESNAKE8]

@@Typical_Garageexactly what I was gonna ask 🤣

[@funfun8095]

@@Typical_Garage Not the throttle body. They go up through the intake valves from reversion. Every 4 cycle engine has reversion, some more than others. A good example is direct injection engines. Look up, carbon build up in direct injection engines. A major problem with them is carbon build up in the intake tract and on the back of the valve, because there isn't any fuel hitting the valve, to clean it, it builds up a lot more than other fuel systems. Sucks the carbon up, just like it would, rust.

[@Typical_Garage]

@@funfun8095 I always thought carbon build up was byproduct of crank ventilation which is why guys run catch cans.... I feel like the argument against rust falls short once you consider every car manufacture uses cast manifolds which do rust so if rust was a catastrophic issue, these oem cast manifolds shouldn't exist, right?

[@markdepriest418]

Search suppliers in food processing or semiconductor industries for stainless. Prices are significantly less than suppliers in the horsepower industry for exactly or better quality. It's where I purchase and I've saved quite a substantial amount.

[@funfun8095]

@@markdepriest418 Yep. And they should look at schedule 10 and schedule 40, too, for stuff that will really hold up.

[@StationroadRatrods]

Mild steel has never given me issues like stainless has, it’s so much more user friendly. You can weld up a 1/4” gap with flux core and rusty exhaust pipe and it’ll never fail, but if you breathe the wrong way a stainless pipe will crack and if the gap isn’t non-existent when welding you’re gonna have a bad time

[@wadebonhomme2142]

Thanks for the info. It’s helpful.

[@funfun8095]

Weight really has to do with the wall thickness, too. Same wall thickness, with any metal, usually weighs the same. Like chrom moly. CM is lighter than mild steel, it just has a thinner wall thickness per cage rules. .083 CM vs .120 MS. The Chinese stainless we get is lighter, because it's thinner than the MS. Cut a 1 foot section of each and weigh them, then measure the wall thickness. ;)

[@SniderTron3000]

Yeah, I had captions on the video that said it depends on wall thickness

[@funfun8095]

@SniderTron3000 Ah, ok. I probably missed it, commenting on here. It's Scotch o'clock lol Johnnie Walker double black, tonight. ;) Keep up the vids, man!

Another good one 👍👍

[@codypatrick5559]

Not going to lie you got me with that thumbnail. Lol good info man.

[@BDauto86]

Its pretty much cost dependant. You can make both look good, most hotside pipes get heat wrapped anyway. If you want show quality stainless and tig is the move.

[@jakeruffolo1236]

Where do you get your mild steel pipe?

[@boostedperformance4529]

Use whatever you want to use it's your option all you have to do is get are in the turbo and are out of the turbo😊 just use header wrap no one will know

[@evodennis75]

What's your plan for the exhaust downpipe?

[@roycervantes1341]

Good morning,,,,,,,,, Yeee Yeee 😊😊😊😊😊

[@Hogiewan1]

I think it’s the ability of the person and how new they are to adding a turbo. I’ve never had a car with one, driven one, but am planning one. I can’t justify the $1200 rig and time. I will blow it up so I’ll need the extra money. For real

[@funfun8095]

Prime weld sells a decent 200 amp beginner Tig 200-d, for under 500.00.

[@governmentcalamari9785]

What amp dc tig do you think is sufficient for building a stainless turbo kit and on the flip side mig for mild

[@funfun8095]

You don't need much for stainless steel tubing or pipe. 100 amps should be fine.

[@funfun8095]

Prime Weld has a 200amp unit for under 500.00. Tig 200-D, is the model. It's DC only, so can't do aluminum, but good for most anything else.

Morning and any luck finding out about mild steel & rust ? Didn't mean to be insensitive about cost & was trying to save you labor ,time and money in the long run. I found it interesting and I'd use mild steel on a junkyard motor but wouldn't if I spent Bank on shortblock. I watch cause i relate & can't afford stainless either and just wanted to share what i learned cause i relate and not trying to shame after reading comments. Sorry

[@raider9170]

What issue do you think would come about from having a mild hot side on a built engine?

[@funfun8095]

Watch Hidden Horsepower with Jon Kasse, at about the 30 min mark

Stainless is actually heavier than mild in the same thickness.

@funfun8095 correction. 304.

[@funfun8095]

@@davidw.thatmsdguy8952 Yeah, 304 is pretty common. 316 and 321 are a little better, too. A lot of people don't know, 400 series stainless steel Can rust, like 409. It will get a surface rust, but that's it. That's why sanitary stainless is always a 300 series.

[@raider9170]

"mild steel rusts"...... Sure it does, eventually. You think a 16g mild steal hotside is sitting with a bunch of water in or on it? Look at EGT, won't be moisture inside or out and it's not like these damn things are sitting caked in road salt

[@funfun8095]

@@raider9170 Running e85 or methanol your hot side will rust in a week. Watch turbo john, when he was running MS. He first run after sitting for a week, he would blow rust out of the exhaust. He now runs SS Salt has nothing to do with the moisture inside the pipes.

[@funfun8095]

MS is not more durable. That's why you really need to run SS and as thick as you can get, with turbo system. MS breaks down a lot faster with high heat, especially in turbo applications. If you run a whole season, hard, with MS your headers/system, will be worn out, by the end of the year. I have a lot of friends that have done it. 2 of them tried MS on their turbo kits and one had to replace his after 8 months and the other's broke when he went back on in the spring. They both went SS and have been fine, going on 3 years now.

[@raider9170]

This makes no sense at all. The only reason this would be is if they took a lot more care making the SS hot side. Please elaborate on what you mean by "Ms breaks down a lot faster" ...... Metallurgically speaking. Average IAT on a turbo car are far less than the temp necessary to harden MS and MUCH hotter than a temp that would let moisture collect..... So what are you talking about? I have done hotsides in mild for people that have gone anything from mid 4s in the 1/8 to 11s in the 1/4 for YEARS without issue

[@funfun8095]

​@@raider9170Kept it up, then, genius!

[@funfun8095]

​@@raider9170 If mild steel is more durable...then why does everyone use stainless steel valves, in nearly all aftermarket heads and a lot of factory heads? Because stainless steel IS more durable, especially in high heat environments.

[@raider9170]

@funfun8095 I didn't say it was more durable. I said stainless wasn't mysteriously amazingly better and that mild steel hot sides aren't going to suck exhaust rust into your car and kill the engine lol. By your logic..... Why aren't cylinder heads stainless? Why aren't all blocks stainless or aluminum? Why are there millions of vehicles on the road with iron blocks and iron heads and mild exhausts? Who is going to tell them they're in trouble!? You still haven't given a performance benefit even though there are apparently articles all over explaining it. I'm just over here with Josh waiting to be convinced that I'll gain anything by doing a stainless hotsides that it significantly more expensive and significantly more of a pain in the ass to weld.

Does mild steel rust ? Rust will destroy a engine.

[@SniderTron3000]

Any rust would go out the downpipe, it wouldn't get sucked in to the intake

[@ronaldrey8474]

@SniderTron3000 I didn't realize it was only down pipes ( hot side) & didn't realize you didn't mean cold side. I'm not building anything Lol just related to ur builds ✌️ Ty for replying

[@ronaldrey8474]

@SniderTron3000 may be different but Infinity lg SUV had recall and destroyed engines sucking rust from catalytic converter & Lake Speed Junior from total seal piston rings did a segment on it.

[@SniderTron3000]

@ronaldrey8474 oh yeah, I would never use mild for a charge pipe

[@funfun8095]

​​@@SniderTron3000Actually it Will go into your intake tract by reversion. I was just chatting with a friend of mine about this a while back. I watch a video, I think on Total Seals channel and guys smarter than us, like Lake Speed Jr. We're talking about oil analysis where they found rust in the oil from cars with mild steel headers and microscopic wear in the cylinder walls, from it. I just priced out a whole dual exhaust job for a customer and I could get SS for just 100.00 more than MS, only thing is, it will be a little more labor, because I'll Tig weld it.
