606.962 Compound, Twin or Single VGT?
606.962 Compound, Twin or Single VGT?
Hypothetically speaking; if one had a OM606.962 and wanted to boosts power to the maximum HP that stock internals could safely handle, which turbo setup would YOU choose? (IP and injectors will be modified accordingly).
Turbos to choose from:
Garrett TV4502 "twin scroll" (a/r .60 compressor / 1.22 turbine)
Holset HE351VE (modified with 2-way vac/pressure actuator)
(2) Garrett GT2256V's (modified with 2-way vac/pressure actuators)
Would you...?
1. Twin 2256's (splitting duty 1-3 & 4-6)
2. Compound TV4502 (low pressure) and HE351V (high pressure)
3. Single HE351V
4. Other combo of above turbos
My initial "dream setup" would be the 351 feeding the 4502 but idk if there would be enough flow to properly spool the 4502.
Please advise.
From just a little research I did, the tv4502 is only 64mm inducer.
351 would be a 60mm inducer. that would be too close to compound them.
What are the specs of the 2256v?
larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?
The 2256v turbos are from a sprinter. I'm interested in this build as well
I don't know if this applies or not:
The one on the left:
larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?
Hmm. So that is 52 or 59mm inducer correct?
could do the 351 or tv4502 as LP, and the 52mm garret as HP.
Compound VNT would be awesomeness!
I recently read a post that said that vnt turbos really "suck on a MB superengine" but I don't understand why.
This revelation could be the reason my post went generally unnoticed.
Could someone explain the theory behind why its bad or wrong to use a vnt/vgt on a high performance 606t?
Vnt/vgt compounding is my goal.
I think if set up correctly it would be pretty awesome, allowing boost at a low rpm, which in turn should let you put more fuel to it earlier, and as being vnt it should also flow well at high rpm when the housings open a little.
That's just my thoughts
I am also curious why they shy away from variable chargers
Sorry my very bad english but I hope someone understand. I made om606 compound with Schwitzer S2B and S300 with two 60mm wastegates for C126 Merc. Smaller turbo starts spool under 2000rpm and the bigger comes together about 3000rpm and the acceleration is smooth at the end. Now I have just 120cc flathead 7mm and the pump´s feed rate ends but the bigger pump is coming. In a dyno the throttle linkage didn´t go at the end and there where about the ~20-30cc diesel to use so the power and torque left so low. Now the linkage is better and the throttle goes full.
My goal is to get more than 500hp this summer with early spool and smooth acceleration. Spool and acceleration are success for now and more power is coming.
But here you can see how soon compound with this setup spools.
Here is the setup
Some adjusting and pull

Regarding VNT
I have had great success width both He351VE and HE341VE
First home-build manifold and HE351VE this one was giving 2.3 Boost width 2.0 bar EGP. at 5000 RPM
The HE341VE + KKD manifold, has a little more back pressure 2.2 boost and 2.2 bar EGP at 5000 RPM.
They can both handle all my Myna pump 7 mm can deliver.
The way i control it is width home-build controller, measuring both BOOST and EGP all the time and closing the wanes as much as possible, bot newer allow the EGP go higher then 0.3 bar higher then Boost,
That why it is not an EXHAUST BRAKE :-) but spool early.

I am working on serie turbo set up where I have simulated
HP turbo efr 7163 LP turbo and GTX4508R, should be good for >800HP
but if BG is not going to release the 7163 soon I will go on different road
I do not dare to have some all originally components
VNT turbo can work but of Type DVANT so the VNT mecanism do not create to much pressure losses. garrett GTB3576VKLNR with GTX3576R compressor wheel would work for medium out put, or if used as HP unit it will be able to make some power
If somebody is just calling VNT exhaust brake is more telling of that persons limited knowledge in turbocharger technology, if you use old stuff there is no absolute not to make it work
There is big difference in in what generation of turbo is used only garrett have GT Gta GTb GTC GTD generations of turbo, and if you combine there racing turbos it can make dissent boost
and power is just not all about boost, the exhaust and intake system is playing a major part, If somebody is telling you they have a high out put motor with original intake I would say there is plenty more to come
If the exhaust pipe has to little volume vs to short the efficiency of the turbine at high boost is going to be low and big exhaust back pressure, in that case a more axial design of the turbine stage would be prefable
using booth intercooler and aftercooler would help further
then if you have really good amount of energy in the exhaust gases you can super cool the intake to -50 degree with turbo techology, but that is really more for an petrol engine

THe he351VE can easily support 500 HP on a Cummins turbodiesel. Controlled correctly, it should do you fine. This is a well done install. Just a small issue on TC lockup

Hi,
I don't understand exactly what you want, but a well done VGT turbo control is a quite difficult task.To double this is a very great challange for everybody. I think to this you need very great experience. You should try after several hundredth. (although I do not know your experience)
I've seen various control on net tunning diesel forums and these sufficiently reveal the magnitude of the task. To make an actuator is such great task as to size a turbo. It's affect the work of the whole car.
(this "exaust brake" able to goes the car)
It's refer to Garett VGT, I don't know the Holset sytem (yet).

Besides being hard to fit under the hood, I think compound chargers are largely overlooked in the std field. What's not to like? Quick spool and great top end? If I ever had the money (and time) that's what I would be doing.
But as of now I have neither of those luxurys
I've driven a number of STD configurations and the reason why I wanted to try a compound turbo setup was quick spool till the end. VNT / VGT charging might be certainly a good option for the right turbocharger, but the control is much more challenging than the two wastegate guidance if you want quick spool.
Someone says that the hx40super would have got the same results, but the added behavior is not what I want. Target power is now 550-600hp with early spool and I think the HP target is achievable with a new 8mm pump. Now with the small 7mm 120cc pump the combo has shown it´s nature and thats why I want to improve the setup.
Dieselmeken 8mm with 220cc pump has arrived and installed. I have driven some adjusting and now it runs like HELL. Now it acts like CDI-engine reacts immediately to throttle pedal with no lag with a lot of power and it runs till the end very good. I couldn´t believe prechamber engine can react like that. Now there is 2.2bar intake manifold pressure and 1.0bar in bigger turbo.

Some adjusting video 80-180km/h in third gear(722.3 and 2.24diff). Need to low back preboost feed because it now stucks primary turbo´s turbine housing. The IP is great and I have to be careful not to boom the engine.

Oops sorry Now it should work.
I did some adjusting again today.
A couple of rounds preboost feed lower and a couple of rounds boost feed higher and one rounds both wastegates tighter.
Now the preboost feed won´t stuck primary turbo´s turbine housing at pedal to the metal acceleration.
Sweet
Tried to film some video but it´s difficult to film with one hand and steer in other hand(I don´t have Gopro). I try to get someone to film also outside the car.
Yeah Winter arrived to Finland and the Sec went to winter sleep. I reach to adjust it to work better with 2.2bar intake manifold pressure and 1.5 bar bigger turbo pressure and adjust the feed with and without the boost. It´s pretty difficult to adjust this setup with this 8mm pump but no impossible at all I can assure. So sad I couldn´t take it to dyno and adjust more because the damn snow. My goal was reach to 2.8-3.0bar intake manifold pressure and 2bar bigger turbo pressure with some minor smoke. Well now it´s time to make this setup better to next spring like Holley hp150 lift pump and better fuel filter bracket. It´s going to be Bosch fuel filter bracket with 14mm couplings and some more small modifications.
I update this thread perhaps next spring next time but if someone wants to know more about the setup or else I follow this STD site.

I got rid of the original actuator and used egp and boost to control it. Basically egp pushes vane ring to open-position naturally.

I have a hx35 with a 12 cm housing and a k29 with a 20 cm housing both are split exhaust housing. I have been thinking of using them in a compound setup but only using half of the hx35 split housing. I would use a 50 or 60 mm wastegate to bleed of the exhaust to the second side of the k29. Just trying to get more power with less smoke.

There is a fellow on 4btswaps that made a electronic controller to control the 351 with the original actuator, pretty neat, I think it would help spool and top end power compared to EGP/boost.
Those are Both pretty large chargers if your going to daily drive it, definitely wouldn't cut down on smoke because they wouldn't come into boost until late in the rpms.
What size is a k29? I know a k31 is 71mm inducer, never heard much about a k29

The hx 35 boosts real good with a 12 cm housing I get 5 lbs at 2000 with using both sides of the exhaust housings. I figure I can double that if I only use one side of the 12cm housing.
The k29 flows 65lbs of air so it is good for 650 hp. Not sure on the size out of town will measure it when I gr back . The hx 35 is only good for 300 hp before it is being pushed to hard.
The hx35 is 56mm inlet, and a what little research I did the k29 is ~47? But the turbine wheel is massive, and would probably outflow a hx35. So if those specs are right, a k29 is no bueno for twins
http://www.agpturbo.com/borg-warner-k29-3775-fmw/
I am not sure but this looks like my turbo but I think my exhaust is a t6 with a 20 cm exhaust. I will be home after the fuirst of the year and will get measurements to confirm.
If those specs are correct from agp, it wouldn't be too bad. But it'll still be a smoke screen until that 35 lights. A hx35 for a low pressure and something like a hx30 or he221 for high would make a very nice spooling set of compounds in my opinion.

simply use a newer version of the VNT, VGT and it work better, but if you did not understand turbo machinery it can be very wrong and then it is called just bad turbo to much back pressure in my experience, but what do I know...
