Just one out behind the passenger side of the cab through the inside of the bed, funds didn't allow for true duals or I would have put 2

What kind of boost does that turbo put out??? That's more like something you'd see on a tractor, and it still looks bigger than a lot of those!! I'd love to hear that thing spool up, that's for sure! Do you have a hood that fits over that, or is it left exposed?

No hood yet, I'll work on that this summer. The turbo visible is an HT4B from a 400 Cummins (1000 c.i.) and is #3 in the staged system. Mid turbo is HT3B from a 350 Cummins (866 c.i.) and the oem Garrett is still in there, too. I did this mainly for experimental reasons to see how it all works. Boost is pretty good, but running WAY lean now, need to get bigger injectors.
Pulling off #3 for a little while, but I'll play some more with it this summer.
Sounds like a lear jet taking off, too.

WOW! Can I ride in it? I bet that thing once dialed in will really go!
Last NOV I bought a Ram 2500 Cummins and it had dual 4" stacks coming out the bed. I removed them due to the soot and I need the bed space.
I gave them to my buddy to put on his Cummins 2500 flat bed. He ended up putting on 5" stacks. Looks really good. Sounds good too. I got his truck today and boy can you ever hear the turbo sing.
What I really want to do is make mine smoke a lot of black when I want it to. I call it anti-ricer air.

Jesus H tapdancing christ................
That is the wildest thing I have seen bar none............I saw in person a twin turbo corvette up close, and I thought that was unreal, and the car ran high 7s in the 1/4 mile and he let off at half track.............................but this thing OMFG
My hats off...........this takes the cake big time. You HAVE to keep us posted on its progress!
all the best

Neat setup I must say, but forgive my ignorance. 
With that setup the way I understand it, the largest turbo is the intake, you have to suck air in past the #3 turbo, to the #2 turbo, down to the #1 turbo to get initial boost, which in turn is creating more work, but feeding air intake speed to aid the spooling up of #2 and #3 turbo. Once the 2nd or 3rd (or both) are spooled and pushing air down to the first turbo, you are limited by the #1 turbos CFM and intake size. Seems like your trying to shove a pen into a pin hole. No offence, I think it is really neat, especially for experimentation.

Boost is PSI, not CFM. I'll play with CFM's with just using the 4B and 3B this summer. For now, I want max boost, and it goes like this: Exhasut exits engine and spins #1 turbine (oem turbo), then to #2 turbine, then to #3 turbine, then out. Intake: From filter into #3 turbo and gets compressed and sent to #2 turbo, gets compressed again and sent to #1 turbo which compresses it again and shoves it into engine.
The oem turbo works best around, say 30 psi. If you feed that with 15 psi from the #2 turbo then the engine sees 45 and the oem turbo is working in it's optimum range, and the #2 turbo is too. Then feed #2 with say 15 psi, bumps output of #2 up by 15, etc. and the engine soon sees 60 psi and all the turbos are happy.
All this without really getting on the fuel very much. Get on the go pedal and 100 to 120 psi should be possible.
