Can someone tell me, or give a link to explain this type of turbo set up? I like the idea of a quicker spool. what does each turbo do as far as bottom end and top end preformance. I'd be fabing it myself, so pics of a twin setup off a truck would be nice to see if anyone has them. It's probably a dumb question for some and i'm sure it's been discussed here quite a few times but I guess I'm just not smart enough to find them..

 

I will post up pics later. But I assume you're talking about compound turbos the smaller turbo your secondary spools up the primary turbo the bigger one.

 

small turbo for low end big turbo for top end but the smaller turbo spools the big one quicker than if the big charge was by itself

 

allow me to submit my potentially retarted question to add on to this. Given the general concept of compound twins, couldn't you theoretically run trips or quads or even more with the same concept if you had room for all the plumbing?

 

Drive pressure would get to high..

 

Actually, on another site, there was a much posted thread with simulation drawings for a set of triples. Two small turbos (possibly) and a big single..

Now that I read the thread, the photos of the model drawings have been deleted.

Lets talk about doing a triple turbo setup

 

That's right. sorry guys should have been more specific..

 

Yes I have had Trips and Tried to setup Quads but that didn't work.

Now they are not as long as you do the setup right.

Here are some 12 Valve Twins.




CR Twins same Idea.



More 12 Valve Twins



Some Triples and quads on Tractors and trucks.

 

Sweet pics.I read in another magazine that someone bilt a dragster with a powerstroke in it,and it has four turbos on it.

 

You mean this one.
