Turbocharger
The 6.7L uses a Garrett single sequential turbo (SST) with variable geometry, a dual-scroll exhaust housing, and an externally actuated wastegate. This turbo has a pair of compressor wheels that are coupled together on a single shaft driven by the turbine wheel. The design is said to dramatically increase the compressor map's range and functions like a sequential twin-turbo system. The boost pressure will be around 30 psi, the turbine shaft speed will see up to 130,000 rpm, and the whole system was designed to function as an exhaust brake. The compressed air will be cooled by an air-to-water intercooler-another first in this segment.
The turbo is bolted to the top of the engine with a pedestal mount attached to the bearing housing (not the exhaust housing, as is commonly done) for less noise and longer turbo life. The twin compressor wheels are mounted back-to-back on a massive turbine shaft that's driven by a single turbine wheel. The variable geometry turbine uses a relatively small housing that also features an external wastegate actuator to divert exhaust drive pressure around the turbo.(Thanx Dieselpower)

actually depending on your computer setup ya might not want to close the window before pasting.. one of my computers here loses the "copy" if ya close em before ya paste the links... even run into that with other computers as well... windows doesnt normally do it but have had it happen on occasion... just the way people set them up..
Yeah, but I don't believe I should have to load everything to Photobucket first. There HAS to be an easier way? Yes, Yes I am slow. Cannot teach an old dog multistep new tricks
