pictures as promised:)
Well here you guys go. . . a few pictures of the new setup. If for some reason they don't show up here, check out my gallery. . . they will be in there. I drove it pretty good today, with a major boost leak(that I may have taken care of) it was faster in all ways then before. Spools up way faster, low end is crazy, and I was still making 35 PSI with a major leak. The only thing so far I don't like is I lost some of my bark. With the exhaust running through two turbos it tends to muffle it more I guess. I guess its time for more fuel 
And who knows, when I get her boosting all the way maybe the bark will come back. But the turbo whistle is neat also. Anyway, I'm excited about where this project is leading. All I gotta do is take care of that damn leak! Time for another test drive.

What's up with the hose clamp on the compressor outlet of the H2E? Is that the source of your boost leak? From the pics it doesn't seem like it's holding well.
You really went all out to fit that 2nd turbo in the valley. Nice job!

Tim great work!
Just a thought. I was working on a 2000 E-450 box truck with a PSD the other day with the old man. Those vans do not have intercooling! Air is collected a a little horn- like our y-pipes and is fed into the heads. I thought I believe I remeber a discussion that occured on here about intercooling not being necesary, (EPA thing) and you can do without it. Looks Like where you fabbed that restrictive 90 degree output tube from the secondary turbo , you can eliminate that 90 degree and dump straight to the heads.
Anyway, if you dumped the output pressurized air from the second turbo straight into the valley and feed it right into the heads, you may never have to worry about boost leaks ever again.

Hey guys,
Yeah know the compressor outletclamp doesn't look like its sealing, but it is. The boot is just longer than the mating surfaceof the turbo.
Intercooling really is necessary for what we're doing to our trucks. And especially for me when I'll be pushing near 70 PSI without leaks. Its going to be harder to get it all to seal, butI'll get it. The passenger side manifold is the source of my leak, PITA but I'll get it to seal.
Pete how are those injectors on smoke? What injectors are they? what chip do you have? Thanks.

Tim those are MiniMee stage3, and i have DPTuner programmed for them, so if i hit 140smoke, and drive about 30-40mph, and i get on it i can black out the sun, when i took th truck for a spin, it was 10pm, so i knew it was a car in my rear view mirror, so i puled away and i didnt see the lights anymore, turn up that i still did see a little of his headlights in my side mirrors just the guy drove into the burning forest
so now i know if somone will pis me off he will be chocking within 10 sec

Wow, that is pretty ingenuitive (sp). I have never seen a turbo placement like that before, i say you did a pretty damn good job. There are two things from a restriction standpoint that you could work on- the outlet of the primary (small) charger, you could have a radiused bend tube coming straight off the marmon clamp joint. I dont know if you have seen it, but ThugLike's GT42R has a bend like that. I have a pic of it somewhere. And the other thing is the intake plenum air routing, of course it looks restrictive, but what can you do with that little space? did you put a divider inside the pipe where the piping splits for the passenger side head? Logic would tell me that at lower boost pressures, more air would tend to go to the driver's side with less restriction. But otherwise that is amazing, it was nothing how i expected seeing two turbos placed in there, cooooool.
I sure couldn't do a project like that.

Placement
Thanks for all the feedback guys,
Kris, That bend of the stocker turbo is extremely tight. notice how it buts right up against the H2. I would have radiused it but after I would have cut the elbow, it would have left and oval shape to weld the circular flange onto. So not much I could do. At some point I might cut that flange off the turbo and use a boot to connect the turbo to an elbow. As for the plenums, they don't seem to have caused any problems yet, motor runs smooth as ever. and I hardly ever cruise withough some sort of pressure built up now!
Anyway, there is all sorts of small issues that still need to be worked out, not the least to mention is that boost leak. Tomorrow I'll be fixing that. Anywho, I'm sure more issues will come up, please keep all the coments and suggestions coming. We'll be back soon,
