Possible Triples Setup, will it work?

Yes but is there an equation to see how much if a restriction the turbo in the valley creates?

as a very general rule, the secondary charger needs to flow roughly half of what the atmo chargers are putting out. So first step is to determine how much air you need for XXX(X) amount of horsepower. IIRC, 1lb/m of airflow is good for about 8-10hp? (someone correct me of i am wrong there). So once you decide how many lbs/m of air you need, then you find the primary chargers you want to use. Now that you know how many lbs of air you are going to get from the primary chargers, your secondary needs to have a flow rating of roughly half the big turbos. Thats basically it, shoved into a very small nutshell.

Umm, so, if the secondary charger (valley/high pressure turbo) flowed 100lbs/min, then the two atmospheric (low pressure) turbos need to flow roughly 50lbs/min? Or would the atmos chargers then need to flow 100lbs/min for the formula to work???

I guess I don't understand. So if in a triple set up, the total flow of the atmos chargers needs to be double the flow of the high pressure turbo? So in that example each atmospheric charger would be capable of the same flow rate as the high pressure turbo, or if each atmospheric charger needs to flow half of the high pressure turbo, totaling the same volume of air movement as the high pressure turbo?

If the valley charger flows 100lbs/m then you need to feed it with 200lbs/m. Again that is just as simple as possible, nothing exact. That's why you can take 3 identical turbos and run them in triples.

:thumb: I was wondering about the three identical turbo thing, in a set up using three of the same turbos, would you want a different trim on the compressor and turbine of the high pressure than that of the trim on the atmospheric turbos?

Why wouldn't you if you possess the ability to:confused:

You made a statement, that would seemingly benefit this thread and the forum, so follow it up...

What? Smoke another bowl buddy, I am not on the "it can't be done" bandwagon, if anything I'm into pushing the limits of what can be done and actually doing what others say can't be done;)

So, you care to expand on your other statement, or not

Maybe it's time to put down the book of quotes and make a statement on your own, I'm still waiting for you to educate me/us about how the air flow changes under pressure, and what principles need to be addressed on the turbine side of the system, ie turbine flow and (drive) pressure. Seriously man. Why the run around, just answer the question...:confused:

Just trying to understand...

People have been trying to educate you on this forum for months and what has been the result? You haven't done anything but keep talking about what you have been told or what you think you've been told. Here's another pertinent one you should heed:

Your desire to ask questions is NOT fueled by desire to learn, but instead by the desire to sound knowledgeable.

Are you implying that info that is gained through the forum, books, tuners, and other diesel geeks is irreverent if it is not applied? Or maybe, you are implying that if info is not gained solely through personal trial and error and experience, it is not valid? Or, you prefer to hear and see posts from only a select few that have knowledge that you deem valid? That last one is dangerous, it's a socialistic platform, last I checked, DuramaxDiesels wasn't.

I fear for the damage that will occur to your ego when you fall off the pedestal you have placed yourself on

Knowledge without application, that shows a lack of desire, I have gathered knowledge and applied it

And thank you to all the members here who actually have helped me, thank you, I have learned allot, and still know nothing...
