How To Design A Turbo Exhaust Manifold With Fusion

[@SylvesterBartos]

Hello, Im designing exhaust piping for production,, and I'm using Another method for this type of work.. It's much easier than 3d sketch.. Im creating one component for strait pipes, and second component for elbows / bends, with simple 2D Sketch... Then I'll make copies of what I need, straight or bend.. simply joining them together with "Joins"... Now You can simply enlarge straights, or make changes to elbows, just simply editing 2D Sketch with dimension.. and for rotation You can use position in joins 'settings'.... Simply put,, create straight, and bend parts,, and simply join them together

[@LearnEverythingAboutDesign]

Thats a great tip! So you typically use all weld els and just copy/paste and join them at different spots.

[@eMTeaM10]

Yes, but keep each pipe/elbow as separate components, copy/paste_new command, then you can adjust sweep angle or length of pipe in each component sketch, or from the parameter window. That way, you build the manifold almost as you would in real life, with tag welding and adjustments.

This is definitely going in my favorite videos list. I’ve been pondering about making an intake manifold for a 2.4L Dodge engine. I could be dreaming, but I was thinking about using single barrel intakes. One for each cylinder.

[@LearnEverythingAboutDesign]

I did an intake set of videos awhile back kzbin.info/aero/PLBDfGh8A8kXXkrW-pb6JpzxdqjLW4IFBc that has a few options on ways to model. As for the single barrel intakes, that really depends. Its a game of either high rpm flow or volume depending on your application. For example you see high revving engines being able to use short runners and individual throttle bodies and it works ok. In most cases you want a reasonable size plenum for a turbo application so there is enough volume to fill the cylinders. the "cannon" intakes are pretty common and generally easier to fabricate, but if you are staying NA then who knows :)

[@clutchboi4038]

Will be a waste if it's turbo. Just do a single manifold and look at the new srt4 manifolds that are proven to make power. The newer ones are even smaller than the original style I think they flow better with boost.

[@Eric1960]

Hi Matt you forgot one other method. You can 3d print the manifold. Probably nobody has a SLS metal printer but online are a lot of solutions available to do the work for you. Just to complete your always great videos 👍👍👍👍👍👍👍

[@LearnEverythingAboutDesign]

I can only imagine the cost of that :) Years ago i saw a beautiful intake on a datsun forum where they CNC milled the top and bottom for a 240z and welded them together. It was a work of art but the Billet to machine each piece must have been $$$

[@Eric1960]

@@LearnEverythingAboutDesign Agree it will cost a lot, still it’s an option and in some cases you need the flexibility. I guess this will mostly used in racing cars where is a high budget. But why not try it, you have a nice STL file, ask a free quote at PCBway (for example). Don’t understand me wrong, my input was only to complete your story. In no way I meant any criticism, I love your work on youtube

[@LearnEverythingAboutDesign]

@@Eric1960 No worries I didn't take it as a negative :) but thank you! There have been some high end super/hyper cars that have done 3d printed inconel exhaust components for things like heat shields/pass thoughts on hoods and firewalls.

[@digital0785]

3d printed 316 isn't as bad as one would expect. Esp if you say make the runners separate so all you have to do is weld it together 😊

[@clutchboi4038]

​@@LearnEverythingAboutDesignsubmit your 3d model to xometry and get a quote generated and make a video about it lol.

[@cbdzcbdz]

As always, thank you for the great videos. I always learn a trick or too from each video. I may have asked this before on a previous video, but how would you create a dimensioned drawing from a model like this? How would you show the angle of each bent section? How would you communicate the angular rotation to adjust the out of plane bends? While it is super cool for us to be able to design and visualize parts and assemblies, but if we can produce a documents, or other build instructions, these cool models and renderings are useless. I have used a combination of AutoCAD, Fusion, and a software similar to Bend-Tech to build a header, but I'd really like to figure out how to do it all in a single program, especially if that program is Fusion.

[@LearnEverythingAboutDesign]

yeah that is a tough one for sure making a drawing for something like this. So if you were using say bend-tech often times the entire primary is a single pipe that gets rotated and bent and its figured out from a step file/3d model. For something like this if you needed to make a drawing in say Solidworks you can import annotations from the sketches and include them in the drawings. So if you did the first arc out of the head plate and rotated it 30deg toward the front of the engine then you could have that dimension imported. Sketches in fusion drawings doesn't really work so great and you can't bring 3d sketches into a drawing unfortunately. So i don't really have a great answer for that other than manually recording the bends, angles, and lengths from your 3d sketch and doing a generic table in the drawing to capture that info. I wish I had a better solution. IF your 3d pipe runs were defined by projected 2d sketches you might be able to get away with that by showing sketches in the drawing....might...

[@digital0785]

Perfect I have a manifold I need to finish and I hate making runners 🤣🤣

[@LearnEverythingAboutDesign]

Yeah generally I opt to "rough" it out in CAD and build by hand.

[@virtualman490]

Hi, congratulations by your channel is simply great. I'm fusion 360 professional user like mechanical engineer and I like so much that you share with us all this amazing desing content. I want to know if you give certificates on that courses that your offer?

[@LearnEverythingAboutDesign]

Thanks! I don't personally offer certificates. I have considered it on my www.learneverythingaboutdesign.com website, but not sure how much value they would hold in a traditional sense. I do consult for Autodesk and am involved in all of their Fusion and Inventor certifications. you can find them on the autodesk website under Certify.

[@Sugarkryptonite]

Great vid, thank you. 3D sketches always gave me problems.

[@GeryS.]

Me too, that's bc the implementation in fusion is just subpar imho!

[@LearnEverythingAboutDesign]

Yeah.... I did start the video warning it was painful :) 3d sketching anything other than straight lines along XYZ or doing a 3d spline with references is very tough to control. I certainly prefer the straight line and fillet method and just buy some bulk prebent sections of tubing.

[@Sugarkryptonite]

@@LearnEverythingAboutDesign Yes you're right that was a much easier way!

[@adambergendorff2702]

Excellent video, liked the second method much more!

[@LearnEverythingAboutDesign]

Me too ;)

[@walrus68000]

I may do something like this in future but using Xometry to make the pipes so they are bent to spec for the model and have fewer welds.

[@LearnEverythingAboutDesign]

If you end up printing something you can get away with way cooler shapes and non round cross sections! I have never welded 3d printed metal before. I have soldered to it before though. I wonder how welding would work.

[@lubingmoreno]

Hey Matt great video

[@LearnEverythingAboutDesign]

Thanks! I think i saw a comment from you asking about the radius. Most of the time you will have that info provided by the manufacturer. www.aceraceparts.com/collections/weld-fittings-weld-els/products/weld-els-short-radius if you look at that chart at the top it lists centerline radius of 2.25in (57.15mm). Not all suppliers will have that info and you may need to do some digging but a good bit of them do.

[@GENPERFORMANCE]

Hi, I recently discovered you in a process of creating a motorcycle part, I wanted to know if you could advise me on the best possible solutions. For example, I would like to make a 3D scan of a motorcycle fairing to create spoiler (it's fashionable at the moment) and use the 3D scan as a reference to create a non-parametric part because motorcycle fairings often have complex curves. Do you have any application advice to use, because I can't do what I want on Fusion.

[@LearnEverythingAboutDesign]

I have a video on doing a tail section, and any of the videos specifically on modeling form parts off scans would work. kzbin.info/www/bejne/oIKwZa15e79sr7s do you have a scan now?

[@NORAVPN]

hi can you make a tutorial to modeling car steering wheel ?

[@LearnEverythingAboutDesign]

I can add that to the list. I did one years ago (2013) www.oreilly.com/library/view/solidworks-surfacing/9781771371506/)

[@tyebraun]

Love your videos but you go on way too many tangents man, it’s so hard not to zone out.

[@LearnEverythingAboutDesign]

Yeah I hear you! I try to answer every question that might come up as I go. Even with all the tangents I will still get a dozen questions ;)

[@cushmfg]

@@LearnEverythingAboutDesign Complete disagree with OP comment, the tangents are where real learning happens for me, but it's just really hard to index the videos based off of that from a learning standpoint. But again, the tangents are super helpful for advanced learners
