When looking to upgrade the performance of your 6.7 Cummins, wouldn't you prefer something that installs easily AND delivers the power you're after? You can with the Stealth Mach 1! This turbo outflows the factory charger by 30% and can support up to 650 rear-wheel horsepower while maintaining all factory emissions.

The crown jewel of this turbo is a custom 11-blade compressor wheel that delivers a wide efficiency range and can drive 42-45 psi of boost. It is built from light weight, yet strong, billet 7075 aluminum and will aid in reducing or even eliminating turbo surge when towing. On the opposite end of the turbo, the turbine wheel has been upgraded, as well, to deliver a distinctive sound and provide better efficiency to reduce exhaust gas temperatures (EGT's) and reduce drive pressure when under load.

To properly match the entire turbo, a custom Calibrated Power exclusive vane-and-shroud plate assembly was produced, dubbed the Stealth Nozzle Ring. This was precisely matched to the larger turbine and gives the turbo a wider volute path for class leading load performance. This wider path was achieved via taller and wider vanes that are capable of extracting more energy from the turbine, literally sucking the air out of the engine faster than stock, which in turn drives the shaft faster to bring IN more cold air.

Finally, this is built from a brand-new turbo and genuine Holset electronics, meaning no core charge, and has been pre-calibrated, with no custom tuning required!

“Brown” floating shelves
Color: Brown, Number Of Shelves: 2, Size: 60"W x 6.5"D, Color: Brown, Number Of Shelves: 2, Size: 60"W x 6.5"D
These shelves are great, easy to install. My only complaint is the color is not quite what I expected. I ordered “brown” and they look a little more “walnut”.

Holes in brackets are not spaced for studs!
Color: White, Number Of Shelves: 2, Size: 67"W x 6.5"D
So the quality of this not great, but good enough and they look nice enough on the wall. However, the bracket holes are not spaced at 16" intervals. WTF? I'm not sure who designed this thing. The molly plugs that came with it look OK, but to play it safe I used a cobalt steel drill bit and made my own holes in the bracket. Easy enough with some wd40. My other pick with this is that the screws to anchor the shelf to the bracket are black and and very obvious... they should have supplied some kind of cap.
