The Redesigned Duramax Engine

Chevrolet has recently announced that the 2017 Silverado HD will now offer the Duramax 6.6L V-8 turbo-diesel engine. This redesigned engine brings 445 horsepower and 910 lb.-ft of torque- a 19 percent increase in max torque over the current Duramax 6.6L- and the best the Duramax has ever offered.

In addition to the power updates, the turbo-diesel’s performance is even quieter and smoother than before. The engine noise at idle has been reduced 38 percent.

“With nearly 2 million sold over the past 15 years, customers have forged a bond with Duramax diesel based on trust and capability,” said Dan Nicholson, vice president, Global Propulsion Systems. “The new Duramax takes those traits to higher levels.”

Sharing only the bore and stroke dimension of the current Duramax 6.6L, the new Duramax will be using a new control system developed by GM; however, the engine’s signature low-rpm torque production has not changed, offering 90 percent of peak torque at 1,550 rpm and sustaining through 2,850 rpm.

“Nearly everything about the Duramax is new, designed to produce more torque at lower rpm and more confidence when trailering or hauling,” stated Gary Arvan, chief engineer. “You’ll also notice the refinement improvements the moment you start the engine, and appreciate them as you cruise quietly down the highway - with or without a trailer.”

The 2017 Chevrolet Silverado HD Features an All-New Air-Intake System Fit for the Worst Conditions

MidMo Powerhouse is excited to announce that the 2017 Chevrolet Silverado HD will feature an all-new patented air intake system that is designed both to cool down the engine during intense driving conditions, and to increase engine performance. In fact, the new system will provide 60 percent of the air used to cool the Duramax diesel engine. 

The revolutionary air intake system is housed within a hood that is significantly larger than the hoods of HD’s past. This system feeds air to the engine that is roughly the same temperature as the air outside, allowing for increased vehicle performance as well as power and speed maintenance during even the worst driving conditions. 

Eric Stanczak, chief engineer of the Silverado HD explains that “the 2017 Silverado HD was engineered to provide maximum utility for our customers.” This HD’s engine can breath even when blocked—the air filter housing pumps 40 percent more air to a location within the truck’s fender, which then goes on to fill the engine’s combustion chambers.

In order for the engine to run at its peak performance level, the air must not only be cool, but dry as well. Chevrolet has perfected the new air intake system even further by adding an air/water separator, which takes in air at such a high velocity that it is separated from any humidity or water. It then drains the water through a valve. 

The 2017 Chevrolet Silverado HD is expected to hit dealers later this year. Head to Jim Butler Linn Chevrolet, your Mid MO Chevy Powerhouse!
