This really shouldn’t make a difference because, there is back pressure and the turbo is the mute point for total exhaust flow. Tube diameter and length would only change the amount of time it takes to “fill” (lagg) Only benefit I can see to running this billet mani is, packaging. Stock Exhaust manifolds on LS engines have proven that, it doesn’t take big tube headers to flow enough exhaust to make big power numbers. The Turbo is the restriction.
Great product, very impressed , a little tip with the TIG welding , keep the filler wire inside the gas coverage, each time you pull it out the white hot tip is contaminated by the atmosphere. I'm in no way being critical, just trying to be helpful. (I've been a coded welder for about 45 years) Cheers.
@@sheromemyers2725 are u criticizing him? He was just giving some welding advice knowing how to tune powerstrokes is not a requirement for tig welding lol
I'm not sure turbo manifolds utilize scaveging Dave. It's all gas under pressure which makes the fluid dynamics the most important. Flow and restriction and turbulence.
Well scavenging is important for high revving NA gas motors, but turbo diesel motors have boost to shove air into the cylinder. As long as the boost is higher than exhaust back pressure there's a pressure difference automatically and no valve overlap swirl is needed for fuel mix because of direct injection. That's why they almost always have log style manifolds. BTW I'm dying to see the widebody on your Trackhawk Magnum!
@@NeonAvantium oh see I must have missed the diesel part, I saw the first manifold and assumed lol. But the whole cnc aspect is really cool, I love new cnc'ed parts.
@@Junkyard_Dave no doubt!! they made a gorgeous part. That looks like a great packaging solution with the compact size and the integrated wastegate flange. did some learning on this. Turns out we were both right. And the key we were missing was this is a twin screw manifold. The turbo does the scavenging. Great engineering explained vid on this: th-cam.com/video/T7JTRRlSEYI/w-d-xo.html
I love how you guys applying ingenuity and creating different approaches to solve various problems. Hopefully one day you will have a metal 3D printer, then you’ll just print om606 from scratch.
@16:30 Yes, a clear difference in size, but you are comparing and equal length manifold to what is, in effect, a modern log style manifold. Great to see that CNC manifolds are now starting to become a “thing” - excellent work, and kudos for not pretending that it’s all black magic secret squirrel. 👌
iv'e been watching your yolls build videos for quite some time now ... i lust wanna say that iv'e never wanted to build an engine all these years as much as i wanna build a 606 now , with all the billet parts you can supply , the biggest turbo and the baddest pump you build .... man oh man if had all the dough i ever wanted a whole bunch of it would be on its way to you guys at DPUK ..... an old 123 or 124 wagon rusty old VOLVO old AUDI or BMW ...... aaaaah ... the dreams floating around in my head i cannot even fully describe .
@@MrDOHC1JZ You can still make a lot of power with unequal header length. Considering the massive space saving this gives, it is worh it. in worst case, just fit a bigger turbo. Now there is the space for one
I really like the manifold design however don't you loose tuning that equalize the exhaust flow? The tubes are the lengths they are for a reason aren't they. It's not just random pipes.
It's a manifold that will flow like headers. Color me impressed. It's a beautiful piece of work but sweet merciful Lord in heaven I'd hate to see the price tag.
Nice job and and really need design - but you got a major “negative” flow point. At the turbo Flansch, where the flow comes Into a sort of had angle - idea is to make the neck of the turbo Flansch longer and round so the flow gets a easy and smooth angle right before it meets the turbo and the wastegate But very nice. Love to see and test it on a tractorpuller
Interesting. Do you have any data to back your claim? Seems these guys took time to flow model their design and they probably have the test data available to back their claims, so I'm wondering where your test data is that shows this "negative flow point." Would be nice to compare the two.
Great product! A tip for speeding up the finishing on the mill, without sacrificing surface roughness; when finishing you were using a z-level strategy. Next time use profile finishing, and then across. Use inserts with slightly a larger radius on them, and you’re golden.
awesome work. as far as comparing to the tubular manifold, I guess I look at the fact the tubular has tenfold more surface area+ thinner walls- combined with the fact that HEAT is energy... so scavenging every BTU possible to drive the turbo is quite beneficial. 👍👍👍
I'm here in canada, looking for an om606. It's great knowing you guys/gals have been doing the work to make all the aftermarket parts! Cant wait to get this manifold. One of the most beautiful peice of machining. So excited
That thing is trick ! I've been keeping an eye on yalls business and setups as I want to run a Merc diesel in a jeep project. If it happens your products will be on it.
I am interested in how the unequal vs equal length headers will perform and sound. The old cast iron Saab 900 turbo header makes it sound a bit like a old fishing boat, because some of the exhaust pulses hit the turbo at the same time, because the last cylinders takes longer time to travel to the collection point.
Real nice product, I am really impressed. if machining time wasn’t so much of an issue you could add a recessed groove between the runners on one half and have a positive extrusion on the other half. This will both align the two halves and generate a more torturous gas path between the runners. With the current design the gasses are likely to be able to mix ‘slightly’ between runners when hot and the gap opens up slightly. Maybe this is not a problem so doesn’t need a solution. Might be nice to try doing a titanium 6-4 version for fun, although post weld stress relieving might be necessary (although this might be done for you by the hot exhaust gases).
Cooles manifold I've ever seen, by far. Hope it works as good as it looks. Who needs fancy porting jobs when you can just get it right on the first go?
I saw so much bad talk about these when they were first posted but this looks like a solid, well thought out part. Interested to see the back to back 👍🏼
Could an identical part be used as a plenum on the induction side DieselPumpUK? The symmetry of this hanging off each side of an m103 would be very appealing.

My guess is packaging. Rotating the turbo horizontally takes up more space, which would force the entire unit to be shorter creating flow restrictions elsewhere.
beautiful this is art ! i love the fact that u take care of old legendary engines like the om606, i would love to see a video of the flow dynamic of this piece on solidworks and a comparison on dyno. ♥️
We have similar manifolds on diesel trucks here in the states by Steed Speed. Would like to see bench flow tests of this manifold, impressive design and beautiful craftsmanship btw!
I love billet but this is the first time I’ve ever seen a “regular” part look better than its billet version. Both are beautiful. I do think putting some of tubing shape on the outside of the billet one would make it look better...not so much like a giant block of aluminum (just some light milling to bring out the shape).
Stephen Laverty that's the exact opposite of what you actually want do. Exhaust manifold wrapping is a thing for a reason. You want to keep the heat in, not out.
this made me go all weak in the knees! i wish my Ram Power Wagon was a diesel and could convince these guys to do a billet manifold for it...good lord...
That would have to reduce lag...the gas doesn't have to travel as far as the tubular header's... such a great idea i can't believe anyone could possibly talk shit about this creation... seriously guys its great keep up the good work
This is exciting. SteedSpeed makes billet stainless manifolds for much larger diesels. The Cummins 6BT is one example. 1:33 Yes, this is also something that is found on Mitsubishi Evo engines.
Awesome machine work and engineering. I enjoy your videos from across the pond and wish I could have some of the parts for my W140s. They could definitely use some more power.
This is way late for a comment, but..... my old R/C nitro truck had the same issues with its exhaust port. The engine side was rectangular and the exhaust pipe was round. The wielding around the flange that attached the two was, like you said, a wall. So rookie me went to town with a Dremel tool and some bits..... easily made the engine rev faster, higher, and made ~10% more power. As I side note I had an '79 300sd. With a OM617. I really wish I knew about all the stuff you can done with that and this engines.
Very interesting, the flow paths certainly look more fluid. Off a whim my money would be on the billet having a more efficient flow stream, allowing earlier transient response. Please dyno them!!
Just a thought... If there is a gap inside manifold where gases can pass then there is a chance that the manifold twist and break. If you make all connecting surfaces like a V, squeeze the parts together before welding it then it will be a tight seal everywhere. Or you make a groove and seal it with copper or steel wire like on cylinderheads
Koenigsegg showed off a billet turbo manifold from titanium and it was canned. In one of his interviews he stated they surpassed it in performance with their current design, which ended up being welded tubular design. So i hope the performance of this for you works out my friend.
I bought the fabricated manifold from luke and I have the nice cast one aswell very nice products. Sadly I had to modify the tubular one to fit in the w202 but oh well.
Great design work, the full flow ports are nice. I'm not sure about the uneven runner lengths, there'd be little pulse scavenging effect with this design, and the sharp 90 deg turn gas is forced to make heading into the turbo flange are questions for me. I'd be eager to see a dyno comparison between the traditional and billet manifolds to prove the design. If it makes the power then farewell glowing bunch of bananas.
This set up will work perfectly on engine bays where space is limited, this is a super compact design which offers the OM606 in many vehicles where the tubular will not fit. 5 stars !
Nice work done by you guys and you are pushing me up to own one of that amazing engines But before you lose to much material and time building this headers you need to check the efficiency of it on dyno It may have opposite effect You can see how much mazda R&D put effort on there engines headers to prevent the turbo back pressure pushing from one piston to other But im very happy to see such a nice product Nice work and i wish you the best
Thermal... Vibration... torsion stress from the engine rotating when accelerating hard. Idk ... this manifold looks good. And I'm no expert by any means but I think I would stick to tube headers . There equal length. Gradual turns ... I could be wrong...
Gorgeous part! absolutely beautiful, but I have some doubts about the sharp angle of the turbo and wastegate flanges relative to the ports. A really sharp bent there. I'm far from an expert but I have the feeling boost might be a little hard to manage too for that same reason. I have a feeling that the collector on the tubular manifold has a more efficient design too
You guys should get them cast. Far more efficient. Much less costly for you and the customers. You would then have no worry about the clamping between 2 halves and could simply finish them in house to ensure fit and finish. Also, not fair comparing packaging because on one side, you have equal length headers. Do equal length billet and it'll weigh 10 times as much. Conversely, you could build a very similar manifold with tubes much more akin to a classic log type and have no packaging issues. Of course, it would be more difficult to match flow efficiency at the elbow to the turbo flange but it would be lighter and marginal in packaging differences. Casting would be most efficient by a mile and you could probably reduce mass in the webbing, especially between 3 and 4. I like the idea of carrying port profile all the way to the flange but the manufacturing process is a massive overcomplication. Food for thought.
Awesome piece would like to see both of those manifolds back-to-back on a dyno
Yeah need to test see if it performs
Certainly looks pretty and saves space, but when push comes to shove....performance.
Edit: Especially with the long-tube Vs short....
Or even tested on a flow bench
This really shouldn’t make a difference because, there is back pressure and the turbo is the mute point for total exhaust flow.

Because they only understand some degree of airflow.
Am i the only one that sees a problem with boost creep bc the wastegate has to work against the flow if exhaust.

I want to see someone machine this out of inconel now. Imagine how insane that would look.
Awesome work Lads love it don't listen to the haters👌👍
I'd be putting bolts through the center to hold both sides together. This is going to warp and separate the two halves between the runners.
It would be really cool to see a dyno video of both manifolds im interested to see how much of a difference their is?
Makes sense, I'd love one please. Could you do a barra 4.0.
That would be epic
You guys should get them cast. Far more efficient. Much less costly for you and the customers. You would then have no worry about the clamping between 2 halves and could simply finish them in house to ensure fit and finish. Also, not fair comparing packaging because on one side, you have equal length headers. Do equal length billet and it'll weigh 10 times as much. Conversely, you could build a very similar manifold with tubes much more akin to a classic log type and have no packaging issues. Of course, it would be more difficult to match flow efficiency at the elbow to the turbo flange but it would be lighter and marginal in packaging differences. Casting would be most efficient by a mile and you could probably reduce mass in the webbing, especially between 3 and 4. I like the idea of carrying port profile all the way to the flange but the manufacturing process is a massive overcomplication. Food for thought.
Looks awesome. Would like to see how it performs, especially with wastegate control.
06 build? Not sure what car,but absolutely beautiful.
