what a beaut!
Sloppy Mechanics are you planning to do a dyno test comparing this to the standard undivided log? Would be great to see if it’s worth all the work. Anyway it’s cool and unique.
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.
Exactly, this header looks nice but has no benefit for a twin or even a single scroll turbo....
also even if the firing orders had been correct, the fact that they were made with unequl length primaries would have had the exhaust pulses arriving all over each other at each volute. Having the firing orders array + unequal length primaries means that this is just a divided flange on a non twin scroll manifold. This setup isnt going to run well. Its a poor single scroll manifold design that incorrectly feeds a twin scroll turbo.
Facts!

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"

He doesn't make one for the driver side does he?
That’s a real work of art! Anybody that’s try fabricate at home can appreciate all the work involved.
I’ve tried this last year actually but ran out of talent... you killed this!
Nice work Joey!
Really outstanding work. Hopefully youre up for another at some point.
Don't you have to split 2 cylinders on each side for a true twin scroll with the LS firing order?
I would not call this twin scroll divided... the twin scroll part is to even out the exhaust pulses, and you need to run the exhaust divided into the flange. (cyl 1-3 and 2-4 for a 4cyl) this is more like divided banks... not sure how this evens out, and I am afraid that the exhaust will be restricted in that manifold.. but, hopefully we get some dyno papers proving me wrong!
Yeah, with any crossplane v8, but you would need a twin turbo setup for that, i still think this will be better than a single scroll for both banks.
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.
Having Fun same here! HD Diesel
FrontYard4X4 that’s cool. I work on heavy equipment in underground mining at one of the deepest mines in the world currently approaching 10,000 foot deep mark.
Having Fun well that sounds like a good gig!
Provided the results are acceptable, that would be awesome for tight figment application, AMC Hammerwagon swaps etc
Super clean work! I cant wait to pick up one of your log manifolds when I ready
I need one of these idk how good my t4 to t6 adapter is gonna do
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.
I’d be interested in building one of these. I’ve wondered many times how much a twin scroll would work.
Keep The Videos Coming! Also, Great Custom Work You Did For CSP! Well Done @FSP...
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!
I did make the template slightly larger, but sometimes things still don't quite always work out as planned. It got me close enough, so overall I think it was worth the time.
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
Do you get the benefits of twin scroll if you don’t have alternating firing order grouped together?
Keep dropping
The last outlet seems to be smothered when plated
She'll be alright.
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!
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
Nice work! How many hours went into this?
10-12
Do I have to add the plate in the middle for a turbo?
I love how you bead blasted it afterwards! really ties it all together!
@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.
one time thing. This was an incredible amount of labor, I'm not sure small benefits would warrant the cost when compared to one of our "standard" headers
Absolute work of art, let’s see how it works now
Nice. 👍
Subbed.
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.
Thank you for the sub and purchase. It means more than you know!
@@FSP3 I'll be making another purchase for the combo log. Perhapse on black Friday if you run a special like last year
Hello. Any update on how this worked? Thanks.
As far as i know it’s still on the truck working just fine.
Initial feedback from Matt was that it worked quite well and helped with spool of turbo
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 :)
Will you build some log manifolds like that for a bbc
i dont think so. Not sure it would be popular enough
That came out sweet👌filming is distracting right? Subbed ya👍🏻
My lord that is so turbulent!!!🙈🙈🙈🙈
Made 4 digit power numbers 🙊🙊🙊
Bad ass
Awesome
thank you
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
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
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.
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?
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 ?
It doesn't get much better than that!... Nice work!!.. I'll take two plz!
Damn good work but you should have used 309 filler rod for welding the carbon steel to the stainless
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
Love the work
Damnit great job you out done yourself you maybe trying to offend the sloppy style lol good stuff
Super clever. I really enjoyed watching. Thanks
Smarter not harder hombre 😎👍 i like, I subscribe ✊
Where do u get the material for building ur own exhaust manifold for turbo setups
Awesome work mate! Love how simple it is and your approach to the problem. Keep up the videos!
Excellent work.Form and function, your hard work shows.
Does it still reduce the turbo lag?
We never got any official data. But matt did say he felt it spooled significantly faster than his old set up. I would like to think his butt is calibrated fairly well.
They should cast Bog Weiner onto the turbo.
This is awesome. How do we get in touch with you
you can find us on just about any social media platform or email info@fahlersp.com
I'll say that this is not something we offer to customers.
@@FSP3 I emailed you and used the Gmail
Sweet!
Nice work man looks pretty cool all smoothed and stealth
Knocked it out of the ball park once again!!
Is the final piece coated with something?
damn! really nice! Im glad your channel popped up
Awesome work! Interested to see more videos 🤙
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
Exactly, Only really beneficial on a v8 if you’re running twin turbos and all 4 of the runners on each side are the same length and paired together at the collector based on firing order.
Awesome work, great fab skills
That HF caliper though... 💀💀
Some bad ass dudes build bad ass stuff with no name tools. Just because it doesn’t say snap-on, matco, miller, Lincoln etc. doesn’t mean they cant produce quality.
@@brianbarsness9828 don't act like I don't have that same one in my shop dude.
How are we supposed to know what you have. I’ve seen guys think they are a mechanic because they have snap-on tools and I’ve seen welders think they are the best because they’ve bought the best welder. All these guys and gals we follow on UA-cam are already better then us. Them making content for us to learn from already makes them better then most. Even if the content is wrong we still learn from it.
@@brianbarsness9828 sorry I wasn't trying to be negative just kidding around. I have that HF one in my toolbox at home and thought it was hilarious it only has 2 decimal places. Just funny seeing at a business but the bottom line is that it gets the job done most of the time
Lol, you guys crack me up. I just use that caliper for 3D printing reference, “yup, it’s a quarter inch-ish.”
Inspirational
Looks great
This is epic!!
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.
Hammerhaus Kennel yes, it’s definitely doable. I have not ever tried it with this program, but i have done it with ease in similar software. However, the biggest struggle is getting the printer to print it at the perfect scale
@@FSP3 Makes sense, thank you!
Good stuff.
Hot damn! Good work!!
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?
The other 3 cylinders should help push the exhaust in the correct direction, and the turbine will help pull to some extent as well. I've seen far worse make good power, so I don't think its anything to stress over.
@@FSP3 Good to know like I thought you guy know way more than I do. I was thinking that the turbo would help push the exhaust out and the twin scroll can use it way more efficiently, and it does look very cool. So I hope I didn't hurt any feeling with my question just wondering. I did want to say the finished product is killer nice job on filling there you can even tell. SO did you MIG or TIG the sides I didn't hear if you said?
Nice work
Where can I get your s10 turbo logs?
Will be adding pre-order option to fahlersp.com
@@FSP3
Thank you sir
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
Thanks. We did not do much testing other than Butt Dyno. Matt thought it felt more punchy down low. You may be right on the 02 readings, but most sensors dont survive long under the high heat and pressure of pre-turbo exhaust in my experience.
@@FSP3
Do you make somehting like this for the older SBC?
@@xmo552 we do not
