'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).

Chevy Bolt 200-mile EV going into production near Detroit

Where there's smoke, there's fire, apparently. The rumors of the Chevy Bolt going into production have been proven correct, with an announcement this morning at the Chicago Auto Show that the 200-mile, all-electric Bolt will be built at the Orion Assembly facility near Detroit. GM didn't say exactly when the Bolt will be built, but GM North America president Alan Batey said in a statement that, "We are moving quickly because of its potential to completely shake up the status quo for electric vehicles." He's not kidding. GM is talking about a $30,000 price tag for an EV that can do twice as many electric miles as any non-Tesla mass-production EV today. Previous hints have the Bolt starting production next year for a market debut in 2017, and with all of the accuracy we've seen from these secret releases up to now, we're going to say this is probably accurate until we hear otherwise. We still have questions about the price tag, but for now we'll try to track down more information here in Chicago. Chevrolet Commits to Bolt EV Production Game-changing, long-range EV to be built at Orion Assembly facility in Michigan CHICAGO – Chevrolet this morning confirmed production of its next-generation pure electric vehicle, based on the Bolt EV concept. It will be built at General Motors' Orion Assembly facility near Detroit. GM North America President Alan Batey made the announcement ahead of the Chicago Auto Show. The Bolt EV concept was introduced last month at the North American International Auto Show in Detroit. "The message from consumers about the Bolt EV concept was clear and unequivocal: Build it," said Batey. "We are moving quickly because of its potential to completely shake up the status quo for electric vehicles." Leveraging the industry-leading battery technology found in the Chevrolet Volt and Spark EV, the Bolt EV concept was developed as a game-changing, long-range pure electric for all 50 states, designed to offer more than a GM-estimated 200 miles of range at a target price of around $30,000. The progressively styled concept vehicle features selectable driving modes for preferred driving styles, such as daily commuting, and it was designed to support DC fast charging. "We're proud that Chevrolet has decided to produce the Bolt EV here in Michigan at the Orion Assembly facility," Gov. Rick Snyder said. "Michigan unquestionably remains the global automotive leader.

2015 Chevrolet Colorado GearOn Edition is ready to do that outdoorsy thing

Bikes, skis, kayaks... the Chevrolet Colorado GearOn is ready to accommodate all of them, thanks to a trip to the Bowtie's accessories catalog. The special edition Colorado features the basics of Chevy's GearOn accessories, including a bars package, bed divider and tie-down rings, which can be supplemented with other accessories to haul all manner of outdoor equipment.
