Triple turbos

[DIESEL_POWER]

How do you figure overall volume of a triple setup. One atmosphere and two manifolds, and also vice versa?

What is the question? What do you mean when you say 'overall volume'? Also, who runs two manifold chargers but a single primary?

 

[unfinished business]

Agreed. That's would seem backwards. I don't know about turbos(air), but with liquids when you have two in parallel the flow rate doubles (lbs/min). Then in series the pressures will be additive.

I think the deezulbrahs engine was set up like that.

 

[DIESEL_POWER]

Duramax, one turbo for each side on manifold as stated feeding engine and one turbo on top as atmosphere feeding the two bottom turbos

How would you figure volume add up all lbs per min, one one top and one bottom, or what?

No one runs it this way but gonna try it.

Primary turbo is basically as much as it will flow.

 

[AHall]

No different than any other two stage turbo system. Primary is total theoretical volume.

 

[AHall]

The reason you don't hear a lot about this is because you're losing the benefit of the common triple set.

 

[DIESEL_POWER]

Primary turbo is basically as much as it will flow.

What about compound volume and psi?

You are still limited in volume by what is being brought in through the atmosphere turbo. If that turbo flow 200lbs/min then that is the limit of the system.

That's what I thought. Thanks

I'd be interested to see the primaries on the manifolds, compressor plumbed traditionally, exhaust plumbed backwards.

I've tried to wrap my mind around this from time to time... Wasn't there a Dmax puller that tried this? I remember seeing pictures on here at some point with (I want to say,) two GT42s and a single GT55.

I thought about that too. I wonder if you'd lose some of the compounding by having the secondary drive that far down the line. Dunno, I'll build a set and find out if somebody wants to give me money lol

Would you be better off to compound each bank at that point? say an S257 over a 464 on each side? Smaller individual intercoolers as well?

That's what we are doing.

It appears you're not looking to do it how I described.

 

[vader's Fury]

Interested in this.

I do believe that Andrew Murdock tried it in his blue duramax.
