The new 6.7 L FoMoCo built Powerstroke has an interesting turbo, reverse flow heads, and a bunch of interesting stuff. Discuss... http://www.dieselpowermag.com/features/ford/0910dp_ford_6_7l_powerstroke_diesel_engine/photo_07.html
The design of the reverse flow heads makes soooooo much sense when you see where the turbo is mounted.
The use of two different compressor wheels to a achieve a broader compressor map is pretty cool. That coupled with a variable nozzle turbine would be pretty badass. I'm looking for a 40R wheel, housing, and backing plate for mine...
wow, there's a few pulleys on that engine... I would not want to work on one of those things. Especially because the newer fords need the cab taken off the frame to remove the engine, I guess Ford books the job at something like 16 hours for two experienced mechanics, or so I am told.
Wow, just read its variable geometry, as well as Sequential. Variable Geometry Single Sequential Turbo. That's one hell of a name.
It is kind of sequential. One doesn't come on before another, in a sense. The compressor wheels are slightly different to give the turbo a much larger operating region. One wheel will run out of breath when the other is in the sweet spot. It looks like this one will have the vane position sensor liket the Duramax has had on the VNT for some time. The Ford unit always had the spot for it though, since they used the exact same CHRA. They should really use a turbo speed sensor though.

That would be cool - to know how fast the thing is spinning.... Kinda ricy tho--like the same way an AFR gauge permanently mounted in a DD is.
A gauge that says Garrett on it is anything but ricey. And they are the only company that offers it. It's some work to install though. Knowing how fast your turbo is spinning is soooo much win I can't begin to describe.
