Fabricating a Turbo Manifold THE RIGHT WAY! - Bmw E30 Circuit Race car
Автокөліктер мен көлік құралдары
True Race Cars can be very hard on components, particularly longer forms of racing such as Circuit Racing and Rally. Add Turbocharging and intake restrictors to the mix and things can get even more difficult and break more often.
On this episode of The Skid Factory we bring in a fabrication expert from Goleby's Parts and Fabrication to work through fabricating a new turbo manifold for a BMW E30 Improved Production Racecar.
We discuss the reasons for failure of the original piece, design changes on the new manifold, material choice and welding processes used.
You might be a pretty competent self taught fabricator but there is always something to learn from a pro, so grab a Lemon Squash, sit back and have a watch as Steady shows us how it's done.

English has left the chat.
This was a classic skid factory episode. Good technical discussion, long detailed montage showing the end product slowly materializing into a completed state, and some of my favorite music. When you hear that first beat starting, you know it's about to go down. Great episode lads

An early morning upload. TSF must have remembered the footy is on tonight 😂🙌

Priorities and all that.
A turbo overspeeds behind a restrictor for the same reason that a throttle body before the turbo inlet reduces "lag" and a vacuum cleaner revs up when you block the hose. This seems like the perfect place to experiment with a throttle-before-turbo setup and Haltech DBW logic to defeat some of the downside of the restrictor, if you're keen.

That’s such a good idea. Could be good results !
That is one amazing manifold. Matt is one amazing fabricator. Love seeing the process. Gus is lucky to have such great mates.
As soon as I saw that melon I knew you had Matt on! Glad to see his work get a spotlight - he does good stuff. As a fabricator who regularly builds manifolds it was neat to get a look at how someone else does it
Loved seeing Marty back in your shop!👍
You boys have brought us so much knowledge and new ways to do things we have all done for years, absolute pleasure to watch and very genuine down to earth boys!!!! Don’t stop what you s do we all Appreciate you s 🎉🍻
great episode, honest Al's honesty refreshing
The pace and vibe of this edit is awesome. As with all your content, i feel like building a car now. Good work gents 🤘
Woody and Al, you guys have the best channel on YT. Always enjoyable. Always informative. Don't ever stop!
This is my favorite channel for fabrication and explaining the reasoning behind everything. Much love from the states
Wow, workmanship + 1, that was next level. Thanks for explaining and showing. Looking forward to see this car run.
Best way to learn how to weld is to start welding. I bit the bullet and bought both a MIG and later a TIG and "taught myself" (with a lot of KZread videos). I tried the practice runs on scrap but got bored after about 10 minutes so just started building things. I highly recommend just getting a welder and giving it a crack.
Never thought i'll see an m42 on skid factory 😊
The "that's all folks" at the end of Looney toons was porky pig. I'm younger than Al and I think a little older than Woody.

It's Porky Pig that said it... and ya, Elmer Fudd is the hunter.
This channel I learn so much. Thanks Al for the thought of us enjoying it. Love it cheers
Great episode guys great to see a pro at work, Al your a legend see all Skid Factory vids I have learnt alot thanks 👍
Mad skills Matt, humbling!!!
The smartest people know they don't have all the answers. There's always something new to learn. Keep rocking.
epic dad bit at the start ! As a new dad my self I can relate... its important the young'uns know you learn more from failure than you do from success, which makes the sucsess more valuable
Very nice work Matt.
Made a manifold a few weeks ago based off what I’ve seen on this channel. When I go to do it again I’ll be keen to either implement these ideas or potentially go off the shelf as suggested. I think the thing is that learning and having a go yourself is also enjoyable and you learn something as well. Even if it’s not the prettiest.

I built my first steam pipe turbo manifold a few years ago - purely because I was inspired by Al. I did know how to weld already, but never imagined doing such a project. I'd also be keen to step it up in the future, but honestly, my steam pipe manifold is well up to the job and I doubt it will fail. Sounds like we've both benefited from what we've watched here. 😊
Great!!! nice detailed video again. Having made some collectors, I can say that it still looks much easier in the video than in reality 😀
great to see you getting in the talent to show you how things would be done different if you weren't self-taught. PS: 30:30 it was Elmer Fudd

Pretty sure it's Porky Pig 🤨
Ya bloody legend Al, amazing to share this info and knowledge! Likewise Matt!
Well done Matt great vid guys 👍🏻
Doing gods work as always boys👍 thanks for sharing the knowledge. Love the channel
Quality fabrication, and very articilate on the process. Thanks for the great video and explanations.
Woohoo, up my alley with this one (have owned an e30 for nearly 20 years) Keen!
Sick episode. Glorious manifold 🤙
bro did a great job, superb Matt
I was wondering how it can be this challenging to build a manifold for a M42 in a E30 chassis- but yeah, the car is designed to be left hand drive. Can be a little bit tight with right hand drive
6:45 Respect to the edit there. Good job Woody!
legend Matt. that manifold is a work of art!
I can't wait for some more E30 content ! Woooohoooo
Love this video. I have made rotated up-pipes for my Subaru's using 321ss SCH10 material and its also a great choice for extended abuse. alloyed with Ti so its a bit lighter and more stable at 1300F+. Self taught here as well and looking to build a manifold for my k series now! Ill be referencing this when the time comes.
You guys are kicking goals mate, The Street machine boys are using your stuff on their build😁
Great vid lads, really enjoyed this one
Awesome content, as always
Al - My welding is all self taught out of necessity so it’ll be good to hear from an expert. Expert - yeah I taught myself over the years 😂
Finally some good content again. It's been a while
Awesome video. Love to see aussie workshops work on older euro cars
That was great to watch how to do it properly. I will definitely be taking some of those tips with me in the future.

You go alright yourself Jeff and your honesty and learning process is an inspiration to many. 😊
Totally informative boys.... Have tried this before and my patience wore thin very quickly so Kudos 😅
can't wait for the final put together
Straight up love ya work lads. Al and Woody got it going on. Cheers Boys. Go QUEENSLANDER!!..
Respect to Turbo Yoda for being both the teacher and the student. MUCH LOVE
It was Porky Pig that said "yibidi yibida, that's all folks", Elmer Fudd is the "hunter guy" and was famous for saying "Be vewy vewy quiet, I'm hunting wabbits" and Bugs Bunny was famous for saying "eeehhh, what's up Doc". For reference, see the outtakes.
nice clips and work lads
Nice bit of fab work!
Mad fab video!
Masters at work!
Great video guys! Good to hear Matt explain why he did what he did with setup and the differences to watch for. Learnt a lot today 😊
NICE WORK GUYS!!!!!!
nothing like watching a master at their craft
Would love to see this car back together and running.
That 250 looks so sick
ART. Respect..
Looks amazing 👏 you boys must have seen the old toyota rally "work around" for turbo restriction? Now that was brilliance. Work around null and void with welded aluminium to the housing tho 🤣
every time the best explanation from turbo Yoda (:
Cool to see some IPRA/IP stuff!
'good to see the skid factory huffing smoke like a good skid factory. Cheers guys, keep the best small and local DIY fab shop running, at this stage, combustion engines and turbos are very good for efficient energy output, facts over lies. Gotta mention much preciation for the good knowledge Al has to reveal as always. Sure helps watching a video and getting the bulk ideas together on a project over wrecking materials and so on. What can I say, don't change much lol. Great show. Cheers':[Dan]: b-s: C.©
He made that look easy as someone who has built a few it's definitely not. that turned out mint.
Damn that's a nice manifold! Great informative episode. Hope to see this buggy at Lakeside sometime! Weeeeee
Well done , you can always learn new shit . Your welds are just as good Al .
always love for the e30
Rex Hunt - “Yibbida Yibbida, that's all folks!”
Love it boy about time
Super video gents
If you still get cracking you could try normalising the finished manifold
makes me feel like im at work ! e30s everywhere here each day
Yibbidy yibbida was Rex Hunt fishing 😉
WAIT WAIT WAIT! Lemon Squash?!
Man! I was literally thinking las week, I wish you guys would do some E30 stuff! Have an m42 myself :)
Different kind of video, very interesting though, great job
M42 is an underrated engine imo
Love the old bmw. Think look great still,
Lucky Gus aye lads, pimp ride
Awesome video as always Did catch your tungsten sharpener Could you tell me about it. Good things and bad about it
heck yes
This was great, thanks for sharing the process.
Made my mates exhaust from stainless based on your previous guidance and it’s holding up 😬👍🏼👍🏼 Edit: It did also take me a Saturday and a Sunday in my 3mx3m manspace 😂
Our S13 racecar has a G25 Garrett V band turbo, the V band clamp has split, the V band flange has cracked off the Manifold and after extra supports added to the Manifold the flange cracked off the Turbo it self
I use a tea light for the purge, tea light on tape trampoline at top opening then a half coke bottle over the top with lid off. The tea light burns till the argon makes it through smothering the flame, and then I use the smoke from the candle to adjust purge flow. Not my idea, they did similar for the original F14 Tomcats titanium wing box. Welding in a vacuum chamber, they used incandescent light bulbs with the glass removed, when the lights started blowing, they had bad gas in the chamber. It was the 60's, they were smart.
happy to see you going back to your original content, l was getting close to the point of unsubscribing.
Good to see it still has a BMW engine 😊 all my builds are with BMW cars and BMW engines,
Great tutorial on fab work. Nice job.. I think it would be Rex Hunt the fisherman you were trying to think of. Yibbada yibbada.
I think it’s fair to say that as long as the fixture is decent and it’s allowed to cool it will remain true. To be fair some benches and handrails potentially require more skill than this gear haha. Love your work
Woody, how do you get such nice footage, there's no ******* room at all... Good to see the Matty getting supervised by the hound :)
Hi guys, as always mint video. Anyone have any info on the tungsten sharpener? Tool pro actually make this or custom job?
i learneded.. cheers
Awesome fab work, have you guys looked at ati dampers for it, found it reduced harmonics on a k20R with balance shafts removed in a eg race car, possibly may help this car
metal art 🤘🤘
I wonder if you move the restrictor further from the inducer, can the compressor grab the negative air pressure more evenly thereby increasing power/ reliability. Cheers, great video
The edit is sweet as, Woody.
Slant 4's anything exhaust side = PITA! I remember my Dad fabricating a N/A equal length header exhaust on his Triumph slant 4 and how much of a nightmare that was -add a turbo, nightmare squared! Log headers FTW!
hi,what was the weight difference between the new and old steel manifold,matt has sme wicked skill
