'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).

GM invests $175 million in Chevy Camaro factory

General Motors just keeps rolling out portions of its $5.4-billion plan for factory upgrades over the next three years. In the latest announcement, the automotive giant is putting $175 million into the Lansing Grand River Assembly Plant for improvements to build the 2016 Chevrolet Camaro. The investment brings new equipment to the plant to build the pony car. An upgrade is needed to support Camaro-specific colors like Summit White, Bright Yellow, and Red Hot, and the factory is also getting two robotic framers. A second shift of 500 workers is resuming in Lansing later this summer to produce the model, as well. So far, GM has announced allocations for $2.8 billion of the $5.4 billion in upgrades. The investments include $1.2 billion to improve pickup production, $439 million for a paint shop for the Corvette, and more new equipment at other plants too. Lansing Grand River Plant Tools Up for 2016 Camaro $175 million investment enables production of lighter, more powerful model 2015-05-28 LANSING, Mich. – A $175 million investment for new tooling and equipment for the sixth-generation Chevrolet Camaro, and the return of hundreds of workers to build America's best-selling performance car for the last five years, was announced today. The facility improvements include three new paint systems for Camaro-specific colors: Summit White, Bright Yellow, and Red Hot. The investment also includes installation of two robotic framers, which allow better dimensional control to provide a more precise drive experience. The Lansing Grand River Assembly Plant will resume a second shift of 500 jobs in late summer. The all-new Chevrolet Camaro was introduced on Detroit's Belle Isle on May 16. The current generation Camaro has been America's favorite performance car for five consecutive years, attracting both long-term Camaro fans and new buyers to Chevrolet. To improve on that success, the sixth-generation Camaro elevates every aspect of Camaro with a suite of new technologies, even higher levels of performance and fuel economy, and a leaner, more athletic design. "I may be the luckiest mayor in America today," said Lansing Mayor Virg Bernero. "Gearing up for full-scale production of the legendary Chevy Camaro is a new high point in the more than two decades of extraordinary partnership between the City of Lansing, General Motors and the UAW.

This is your 2014 Chevrolet SS

Think you've waited long enough for this? If so, then you'll want to savor the high-res photos we've so far been given of the 2014 Chevrolet SS, the first rear-wheel-drive performance sedan from The Bowtie in 17 years.
We all know its our version of the brand new VF-model Holden Commodore, but what's under the hood that earns the appellation "performance?" A 6.2-liter LS3 V8 engine producing 415 horsepower and 415 pound-feet of torque. That's 35 hp and lb-ft less than the same engine is expected to produce in the 2014 Chevrolet Corvette. Chevrolet says the sedan will get from 0-to-60 miles per hour "in about five seconds."
Shifting comes courtesy of a six-speed automatic with paddles on the steering wheel, while stopping arrive via four-piston Brembo calipers up front, a single sliding piston in back. The forged aluminum wheels are 19-inchers all around, each set supporting right around 50 percent of the sedan's weight, and the aluminum hood and trunk are meant to keep the center of gravity low.
