I was following along with a build thread on another forum, when I saw something in the way his triple turbo setup that didn't make sense to me. When I asked about it, he said it was done that way in quite a few of the top pullers for a while. I've never seen it before, but I thought I would ask here because I just can't see how it would work right.
Let me start by saying every compound setup I've ever seen whether it is twins or triples or whatever has it so the exhaust passes through the secondary stage first, then the primary stage, and after the secondary then it's out the down pipe(s). On the compressor side the air enters the primary stage first where it is compressed and sent to the secondary to be further compressed before it is sent to the engine.
This is on a Duramax. There are two GT4202R turbos that are each connected to a cylinder bank. The exhaust leaves each of those turbos and both feed into 1 GT 5541R. That in itself seems a little different, but I can see how it might work if the 4202s are the secondary stage and the 5541 is feeding air into them. However, this system is designed so the 4202s are the atmosphere turbos, and the 5541 is the high pressure turbo.
Does anyone know of anyone running a turbo system like that? Do you have any pics or videos of it running? Is there any advantage to doing it like this over a regular setup?
