'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).

LG Chem's troubled Chevy Volt battery plant hiring once again

The Michigan battery plant known for paying its workers to do nothing has turned things around and is now hiring more workers, specifically to do something. South Korea-based LG Chem, which runs the factory to supply the Chevrolet Volt extended-range plug-in vehicle with its lithium-ion batteries, held a job fair recently to bring on 40 new employees in order to meet higher battery demand, according to WZZM, the ABC affiliate for Grand Rapids, MI. The LG Chem factory is in Holland, MI, about 30 miles west of Grand Rapids, and it made its first batteries last year. Prior to that, though, the factory gained notoriety after a US Department of Energy (DOE) probe found that workers there were getting paid to do, well, nothing. That's because demand for the battery packs was so low that it cost less for the plant to sit idle. The DOE was conducting the probe because of its financial grant to LG Chem. But that was then and today is today. LG Chem is looking to ramp up production in advance of the second-generation Volt. That 2016 model-year version is said to have a longer all-electric range and better performance and will ride on a new chassis, but few official details have surfaced. We will know more when we get our first look at the car at the Detroit Auto Show in January.

Recharge Wrap-up: BMW cars to share i tech, Jordan to build solar EV charging network

Jordan is looking to promote EVs and build a solar charging network. The country is waiving import tariffs on electric cars, and is spending $120 million on solar chargers. It plans to build 3,000 charging stations, along with 30 MW of solar power. Some chargers will be powered by solar canopies, while others will get electricity from nearby solar farms. Jordan's solar plan should also help to lessen the amount of energy it needs to import from nearby countries. Read more from Navigant Research, or at Green Car Reports. BMW's mainstream cars will benefit from technology borrowed from the i3 and i8, according to BMW sales head Ian Robertson. In an interview with Automotive News, Robertson said that next-generation cars will use carbon fiber more extensively, and that more cars will get plug-in technology. He said that about half of i3 buyers opt for the range extender and added that it is incorrect to refer to a range-extended electric vehicle as a plug-in hybrid. Read more at Automotive News. The ethanol market should remain healthy despite falling oil prices. While cheap oil could drive down ethanol prices, demand still remains due to the federal biofuels standard. Additionally, ethanol producers may find it cheaper to ship their products as domestic oil production drops and railroad shipping opens up. Ethanol byproducts like distillers grains continue to sell, and foreign demand continues as other countries impose their own renewable fuel standards. Read more at Yahoo News. Via Motors will launch the production of an electric Chevrolet Silverado. The company will convert the pickups into range-extended EVs at its assembly line in Mexico, near GM's Silverado plant. Via has the capacity to produce 10,000 vehicles per year at its Mexico facility. Via Motors Chairman (and former GM Vice Chairman during the early days of the Chevrolet Volt project) Bob Lutz wants to help make EVs mainstream in America, and believes that requires electrifying pickups and SUVs.
