How Do Compound Turbos Work? | Compound Turbochargers Explained | Twin Turbos | Diesel Power Source

I don't know where to start but it's coming . "DREAM TRUCK BUILD" !!!! I WATCH THIS VIDEO EVERYDAY !!!!

[@jamesvaldez4093]

What's the recommended upgrades for a stocker kit? Headstuds? I'd like something set up for good reliability in towing.

[@DieselPowerSource]

Head Studs are never always a good idea. However, we always recommend Head Studs for: 1988-2002 engine over 48 psi boost, and fire rings for over 55 psi boost 2003-2007 engine sover 55 psi boost, and fire rings for over 65 psi boost 2007.5-2018 6.7 engines, over 48 psi boost, and fire rings for over 55 psi boost Our Compound Turbo systems are all capable of over more than 55 psi, but are adjustable depending on truck. For a 5.9L with a stocker kit you can run stock injectors up to about 90 hp injectors. what year is your truck?

Diesels are even more amazing than I thought! :D

this is my next big upgrade !!! COMIN SOON BABY !!!

How do you regulate boost pressure? With normal wastegate?

[@Manuqtix.Manuqtix]

@@davelowets Then you’ll start melting pistons, bending conrods, blowing head gaskets and so on

[@Ethan_LeBlanc]

@@Manuqtix.Manuqtix sounds fun

[@Manuqtix.Manuqtix]

@@Ethan_LeBlanc come on man. We must boost responsibly not recklessly

[@TheOhsemix]

If you need high boost pressures this is your setup. Otherwise just run a single theirs no need to go crazy with a complicated system. It ultimately makes sense on diesels because they can take much higher boost pressure than a gasoline engine. But if you don’t need it don’t over think it.

[@jamesmosher6130]

Usually compound turbos are diesels. Regulating boost isn't a big deal on diesels. As for melting pistons you regulate temp with the timing and amount of diesel you inject.

[@andrzejt1984]

flowing the exhaust gas once the big turbo kiks in is an important topic. Especially when the difference is big (lick stock turbo + S400). The hot side of the small turbo with an integrated wastegate, might become a bottleneck. Any comments on how you solved that?

[@gagepuffinbarger6939]

I was lead to believe the primary turbo was the smaller, quicker, high pressure turbo, not the larger one. Am I wrong?

[@DudeManRife]

I thought sequential turbos fed the intake in parallel and the compound turbos fed the intake in series?

[@JohnJernigan95]

NOT A IMPAILER!?!?! 🤣

[@skeetorkiftwon]

When are you going to add injectors to these "turbo" kits so we can just have our jet engines and boost helper diesels?

[@KaiDragon]

Does the MPG drop or gain?

[@DieselPowerSource]

Gains

[@paullupupa7415]

Can an M11 cummins engine have compound turbo setup?

[@michaelwilson4685]

Yes.

[@Madddog87]

So for instance if have 2 of the same turbos that are rated at 10 psi each and I run them as compound I’m gonna get 30psi total?

[@oldmate6380]

no they have to be different sizes to work properly, eg. the big turbos outlet has to be the same size as the smaller turbos inlet, otherwise changing tube size will cause pressure to go down

[@rodjdhazlee]

Is it possible to install intercooler for better performance?

[@gagepuffinbarger6939]

Most kits should come with an intercooler, depending on the application.

[@Pendawa_Diesel_Plus]

why does the compound turbo have to be the first turbo bigger than the second turbo

[@gagepuffinbarger6939]

From what I understand about compound turbos, the primary is the smaller, and quicker turbo that builds boost at low RPM. The secondary turbo being the large turbo that builds boost at higher RPM.

[@Paraclycopin]

What happens if you put four of those into a 2jz?

[@johnnyappleseed9254]

You only need the 2 as shown. 2jz is an in-line 6 just like the Cummins, no?

[@badass6.0powerstroke10]

You better have enough Fuel with all the Air the Turbos are blowing into that 2JZ !

[@chicago_beats]

This is good for old school cars not modern cars unless they run a small engine. LS engine seems it can handle compound turbo kit

[@johnnyappleseed9254]

These diesels are inline engines.

[@theobserver6639]

It's pretty much a rwin turbo with different gearing

[@michaelwilson4685]

No it's not

[@badass6.0powerstroke10]

I've never heard the word "gearing" when talking about Turbochargers, only gear drives used with Centrifugal Blowers have different gear ratios that can be used. And No, a Compound Set-up is NOTHING like a Twin Turbo System.

[@theobserver6639]

What's the compressor ratio on each compressor of the compound turbo

[@theobserver6639]

​​@badass6.0powerstroke10 I guess it's how you look at it idont claim I know every thing been around diesels my whole life and a family own company ten semis in northern Canada

[@michaelwilson4685]

@theobserver6639 the compressor ratios on a compound or sequential set up at two different size turbos always. Twins are the same ratio hints the name twin, also good luck twin turboing an inline engine.

[@djmjr77]

This confused me a little with the extra info.. wouldn't the smaller turbo create a bottleneck for the larger turbo? Is the pressurized air coming from the larger turbo allowed to leak around the smaller turbos impeller? If not wouldn't the total possible airflow be limited by the smaller turbo.. obviously we know they work, just curious about limitations of usable power of the larger turbo based on what smaller turbo you have.. stupid brain.. lol

[@1stMjolnirMarkV]

The smaller turbo is used to raise the boost pressure of the primary turbo air flow. The primary turbo increases air volume or density for the secondary turbo making the secondary turbo swallow and compress far more air than it could by itself.
