what a beaut!

That’s a real work of art! Anybody that’s try fabricate at home can appreciate all the work involved.

The idea of twin scroll is to avoid the back pressure from a newly opened exhaust valve blowing back into an already open valve. It allows greater boost (= exhaust back pressure) without reverse flow. The arrangement you have used may well have worsened the issue. Generally you'd group cylinders 1 and 4 together in one scroll, 2 and 3 in the other. For a V8, it's hardly going to make any difference to put one bank in each scroll. Looks good though.

"I know Matt doesn't care, But... I kinda care, I like things to look nice, and sometimes we try to make him feel that way too." -Joey Fahler I will always appreciate when my friends have the patience and skill that I do not have to make something beautiful for me, even if i would never "treat myself"

I’ve tried this last year actually but ran out of talent... you killed this!

Super clean work! I cant wait to pick up one of your log manifolds when I ready

I love how you bead blasted it afterwards! really ties it all together!

Really outstanding work. Hopefully youre up for another at some point.

New to this channel. My career is in heavy duty diesels but cars are a huge passion of mine and I love this kind of stuff. From a guy who’s done a lot of welding in my life this man has amazing talents, beautiful work.

As someone who fabricated my own ls turbo manifold , I will be giving you a call to order my next one. 😁 Mine turned out real nice and has lasted 5 years now but what alot of work. Nice job on the twin scroll

Awesome work mate! Love how simple it is and your approach to the problem. Keep up the videos!

Nice work Joey!

Awesome work. Cool to show the fusion work as well. I have been working on learning more of fusion as I go. It's nice to see someone else's thought process. Funny how you and Matt are always downplaying your skill and knowledge. Modesty is a hard thing to find these days. Keep up the hard work. Your Prusa is too clean mine looks like it has been thru a war.

Excellent work.Form and function, your hard work shows.

Keep The Videos Coming! Also, Great Custom Work You Did For CSP! Well Done @FSP...

Nice work man looks pretty cool all smoothed and stealth

Super clever. I really enjoyed watching. Thanks

Absolute work of art, let’s see how it works now

Nice work. I built one very similar for my gto. I didn’t divide it tho because I don’t have a twin scroll. And I taught myself too. I ceramic coated and wrapped mine recently. It looked too good to wrap it but I was cooking alternators so I had to contain the heat somehow.

Damn... this is gorgeous hahaha, great work man looks awesome, subscribed, would loooove to see more auto fabrication stuff, there isn't enough of it

It doesn't get much better than that!... Nice work!!.. I'll take two plz!

damn! really nice! Im glad your channel popped up

Awesome work! Interested to see more videos 🤙

I don't even remember Matt talking about this on his channel. Or if he did it was real quick and not given as much detail as it should've. Neat stuff!

I know this video is 2 years old already but roughly the same time I had an idea of making a sleeper exhaust so it looks like it is 1 exhaust but both exhaust manifolds are kept separate through out the whole exhaust system and having twin tail pipes

Just subbed. Also just purchased one of your last china log manifolds and it should be arriving by the end of the week. Super excited to get rid of my crappy home built hotside for something stronger and more pleasing to the eyes.

Awesome work, great fab skills

I’d be interested in building one of these. I’ve wondered many times how much a twin scroll would work.

Provided the results are acceptable, that would be awesome for tight figment application, AMC Hammerwagon swaps etc

Nice work

Looks great

Love the work

Hot damn! Good work!!

Good stuff.

Knocked it out of the ball park once again!!

So how well did it work out reversing flow on the blades with your arrangement? I would have imagined it didn't spool up very well?

This is epic!!

Do you get the benefits of twin scroll if you don’t have alternating firing order grouped together?

Twin scroll manifolds are about eeking out as much performance as possible from the turbo. This is refreshing to see for the LS world, its been too long coming IMO. Nice skills, can't wait to see the results. Is there any plans to offer the twin scroll to the public ? or was this a one off ?

That came out sweet👌filming is distracting right? Subbed ya👍🏻

thank you

Do I have to add the plate in the middle for a turbo?

Where do u get the material for building ur own exhaust manifold for turbo setups

Nice. 👍 Subbed.

Nice fab work. Curious how it will work out performance as the cylinders aren’t really split for a true twin scroll, but you may still see some benefits. Great use of the 3D printer. Work smart not hard! I havnt used a 3d printer yet. But would it not be easy to make your template slightly larger a then the pipe diameter for proper tracing? Another idea I just had was to make your template, use it to set your vice/jig in a chop saw and giver!

Smarter not harder hombre 😎👍 i like, I subscribe ✊

Keep dropping

way to nice for matt.

Inspirational

Awesome

Damnit great job you out done yourself you maybe trying to offend the sloppy style lol good stuff

Damn good work but you should have used 309 filler rod for welding the carbon steel to the stainless

Sweet!

Is the final piece coated with something?

Great stuff here!! Even if I'm not sure that the twin scroll thing has any theoretical benefit in this application, it's fun to watch you guys try it out! One question about CAD, could the program have just flattened that section into a plane for cutting out of paper instead of leaving it in 3D printing format? If so I need to see if I could manage some simple stuff on that program.

The last outlet seems to be smothered when plated

Nice job Joey. Turned out great - edit - If you need CAD help in the future that is what I do for a living. Hit me up if you need anything :)

Don't you have to split 2 cylinders on each side for a true twin scroll with the LS firing order?

@fahler speed and performance, are you selling these to the public or was it a one time thing? I’d like to see how much one with a T4 flange would cost.

I had to subscribe

Nice work! How many hours went into this?

Hello. Any update on how this worked? Thanks.

That's dope but that far back cylinder port merge scares me and should have been bent more and the entry moved forward to smooth the flow imo cause of how tight it is back there and how abrupt the turn is

Bad ass

I am very impressed with the finished product. I don't want to sound stupid but the end port looked like it was choked down compared to the rest so my question is would that cause a problem with ether choking that cylinder or excessive heat at that point. I just wanted to know it that was a concern or not. I thought it was air in and air out as easy as could be for more power. But if you thought it out or it just doesn't matter with a turbo?

Nice job Joey!! Have you and Matt done any testing on this? I was thinking this would allow a more accurate reading for trying closed loop with a 02 bung for passenger side. Just a thought

Does it still reduce the turbo lag?

They should cast Bog Weiner onto the turbo.

That HF caliper though... 💀💀

Split scrolls are really a straight 6 thing for pulse tuning. I don’t think you see the benefits on an 8 cylinder as much

My lord that is so turbulent!!!🙈🙈🙈🙈

This is awesome. How do we get in touch with you

Where can I get your s10 turbo logs?

the template didnt fit right because your drawing was from two flat circles. drawing a plane between the two created a oval shaped pipe. couple different ways to draw it round, but it still ended up close enough. would be a bit more critical if it were thin wall

Will you build some log manifolds like that for a bbc
