Fabricating a Turbo Manifold THE RIGHT WAY! - Bmw E30 Circuit Race car
HTML-код
- Опубликовано: 30 июн 2024
- 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.

Matt is a wepone, he was my apprentice as a mechanic. So proud of this guy as to what he has achieved. His work is stunning 👌
This is y i love this channel al and woody plus all there friends they are so humble and genuine and dont pretend they no it all and are the best. And its wicked sick car content for us aussies
Wicked sick comment bro
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
Agree mate a classic
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.
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 RUclips 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.
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
The smartest people know they don't have all the answers. There's always something new to learn. Keep rocking.
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 🤨
Loved seeing Marty back in your shop!👍
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.
Yes, the hunter guy they were thinking of is elmer fudd.
It's Porky Pig that said it... and ya, Elmer Fudd is the hunter.
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
Great episode guys great to see a pro at work, Al your a legend see all Skid Factory vids I have learnt alot thanks 👍
The pace and vibe of this edit is awesome. As with all your content, i feel like building a car now. Good work gents 🤘
Wow, workmanship + 1, that was next level. Thanks for explaining and showing. Looking forward to see this car run.
This channel I learn so much. Thanks Al for the thought of us enjoying it. Love it cheers
Mad skills Matt, humbling!!!
Never thought i'll see an m42 on skid factory 😊
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
Well done Matt great vid guys 👍🏻
Quality fabrication, and very articilate on the process. Thanks for the great video and explanations.
Sick episode. Glorious manifold 🤙
Woody and Al, you guys have the best channel on YT. Always enjoyable. Always informative. Don't ever stop!
Doing gods work as always boys👍 thanks for sharing the knowledge. Love the channel
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
😂
Great!!! nice detailed video again.
Having made some collectors, I can say that it still looks much easier in the video than in reality 😀
Woohoo, up my alley with this one (have owned an e30 for nearly 20 years)
Keen!
Ya bloody legend Al, amazing to share this info and knowledge! Likewise Matt!
Very nice work Matt.
This is my favorite channel for fabrication and explaining the reasoning behind everything. Much love from the states
bro did a great job, superb Matt
Awesome content, as always
I can't wait for some more E30 content ! Woooohoooo
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.
Great vid lads, really enjoyed this one
Mad fab video!
legend Matt. that manifold is a work of art!
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.
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
Awesome video. Love to see aussie workshops work on older euro cars
6:45 Respect to the edit there. Good job Woody!
nice clips and work lads
can't wait for the final put together
Masters at work!
ART. Respect..
Finally some good content again. It's been a while
Totally informative boys.... Have tried this before and my patience wore thin very quickly so Kudos 😅
Nice bit of fab work!
That was great to watch how to do it properly. I will definitely be taking some of those tips with me in the future.
Those headers in the Alfa are pretty mint too
You go alright yourself Jeff and your honesty and learning process is an inspiration to many. 😊
You guys are kicking goals mate, The Street machine boys are using your stuff on their build😁
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 🤣
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
NICE WORK GUYS!!!!!!
He made that look easy as someone who has built a few it's definitely not. that turned out mint.
Would love to see this car back together and running.
always love for the e30
Cool to see some IPRA/IP stuff!
nothing like watching a master at their craft
That 250 looks so sick
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 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 😊
Damn that's a nice manifold! Great informative episode. Hope to see this buggy at Lakeside sometime! Weeeeee
'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.©
If you still get cracking you could try normalising the finished manifold
Love it boy about time
Well done , you can always learn new shit . Your welds are just as good Al .
every time the best explanation from turbo Yoda (:
It was both- Bugs Bunny and Elmer Fudd voices, IIRC. About the late '50s and '60s; two of my uncles were projectionists- ran the movie cameras at the theaters, so I got to do a lot of movies. The new "Merican term for that fancy schmancy sticking parts together is "fabricobbling". I don't knw why I put that in there, I just thought you should know.
heck yes
Love the old bmw. Think look great still,
makes me feel like im at work ! e30s everywhere here each day
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 😂
M42 is an underrated engine imo
Super video gents
Man! I was literally thinking las week, I wish you guys would do some E30 stuff! Have an m42 myself :)
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.
Yibbidy yibbida was Rex Hunt fishing 😉
Different kind of video, very interesting though, great job
Great tutorial on fab work. Nice job.. I think it would be Rex Hunt the fisherman you were trying to think of. Yibbada yibbada.
Rex Hunt - “Yibbida Yibbida, that's all folks!”
WAIT WAIT WAIT! Lemon Squash?!
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!
Awesome video as always
Did catch your tungsten sharpener
Could you tell me about it.
Good things and bad about it
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
This was great, thanks for sharing the process.
Lucky Gus aye lads, pimp ride
Good to see it still has a BMW engine 😊 all my builds are with BMW cars and BMW engines,
Hi guys, as always mint video. Anyone have any info on the tungsten sharpener? Tool pro actually make this or custom job?
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
i learneded.. cheers
metal art 🤘🤘
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 :)
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
Need a dyno video of this
