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? In some instances, you can't have your cake and eat it too, but in the case of turbo upgrades, you can with the Stealth Mach 1 64! This turbo outflows the factory charger by 30% and can support up to an enormous 600 rear wheel horsepower with all factory emissions and tuning intact.The HE300VG Stealth Mach 1 64 is the perfect balance of power, drivability, and reliability. With an upgraded compressor wheel, turbine, and variable geometry nozzle assembly, this turbo has the ability to move 30% more air through it than stock, all while providing a better drive/boost pressure ratio than the stock charger. This means not only do you get more power, you also get an extremely fast spool up, comparable to that of the stock charger. If you tow or haul heavy loads on a regular basis this is the turbo for you. Quick spool up means taking off from stops is a breeze and the ability to retain your factory exhaust brake makes braking easier and saves your brake pads. Plus Calibrated's upgraded turbine wheel and HFV technology help to lower EGTs which gives you even more confidence when towing a heavy load up a steep grade. To top it all off this turbo comes with a brand new genuine HE300vg Holset actuator to ensure proper operation.
The crown jewel of this turbo is a custom 11 blade compressor wheel that delivers a wide efficiency range and can drive 41-45 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.
In order 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 achievered 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!

Excellent sport sock!
Size: One Size, Color: (100) White / White / Halo Gray
Molds onto foot, super soft and breathable. A lot of my ankle socks tend to slip or cut off blood circulation. This one literally is a perfect fit. No slip. After playing hours of tennis every week, my feet don't feel sore or bruised. Must buy!

Comfort!
Size: One Size, Color: (100) White / White / Halo Gray
Very comfortable! Thinner than the picture shows, but I like the fact that they are no show but still higher in the back and front to protect my heels and such.

Sizing way off
Size: One Size, Color: (100) White / White / Halo Gray
These were my favorite socks, at least the old style was. They redid them and I was okay with it. However, I don't understand how they are a one size fits most. I tried them on and they were still too big at the top. There was so much extra fabric at the toes. For reference, I wear a size 8.5 women's shoe, typically. The packaging says fits most from size 5.5 to 12. I don't understand how it fits that wide range of shoe size. Definitely returning these and I will be buying something else.
