'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 recalls 64k 2011-2013 Volts over carbon monoxide fears, stop sale on Trax and Encore

General Motors is recalling 50,249 Chevrolet Volts from the 2011-2013 model years in the US and an additional 13,937 exported examples because of fears over carbon monoxide buildup. According to a statement, if a Volt is accidentally left on while running on electric power, its internal combustion engine would eventually kick on to charge on the battery. If this happens in an enclosed space, then carbon monoxide can fill the area, leading to a potential exposure to the dangerous gas. According to GM, there have been two injuries reported due to this issue. To fix the problem, there's a software update to limit the time the vehicle can idle. According to Automotive News, GM is also issuing a stop sale on about 2,300 examples of the 2015 Chevrolet Trax and Buick Encore. In these compact crossovers, it's possible that the steering column assembly could touch the power steering circuit board and cause damage over time. This could potentially cause the system to stop working. Automotive News indicates that the automaker is still working with the supplier to get the necessary parts to repair this problem. General Motors is recalling 50,249 Chevrolet Volts in the U.S. from the 2011-2013 model years to implement a software update that will limit the amount of time a vehicle can be left idling in the "on" or "run" position. If a driver exits the vehicle and inadvertently leaves the vehicle "on" by failing to react to cues and warning chimes emitted by the vehicle, the vehicle's high-voltage battery will drain after a period of time and the gasoline engine will begin to run. If the gas engine runs for a long period of time within an enclosed space, such as a garage, carbon monoxide could build up. GM is aware of two injuries, both related to carbon monoxide build up. The total recall population including Canada and exports is 64,186. Related Video:

Old Car or New Car? 1993 Chevy Camaro vs 2015 Honda CR-Z

My daily life revolves around used cars. As a former fast-talking auto auctioneer, it was once my job to inspect, appraise, and liquidate thousands of cars throughout the United States. Since I put down my microphone and became a full-time car dealer, I have gone from auctioning off 150 vehicles an hour – yes, we really do talk that fast – to buying 150 vehicles every two to three months. I see and bid on everything from $300 Volkswagens that belch more black smoke than a diesel truck rolling coal, to $30,000 DeLoreans that hopefully can go at least 88 miles per hour. The auctions never run out of weirdness when it comes to cars because they sell over 10 million every single year. So with that big number in mind, let me tell you about these two cars that have about as much in common as Mel Gibson and Mel Brooks.Option A: 1993 Chevrolet Camaro Indy 500 Pace Car Edition View 24 Photos This 1993 Chevrolet Camaro Indy Pace Car has all of 4,187 miles on it. Neither of those numbers are a misprint and yes, those are multi-colored stripes on the hood. Every week, I find at least two or three museum pieces that have been stored in the private garage of an auto collector. As you can tell, there are some very broad strokes to the definition and tastes of a collector. It could be a guy who has an extreme case of what I call "Automotive Compulsive Disorder" who chucks 20 or 30 old cars into a field and lets the weather and elements have at them. I once knew a guy, a car dealer at that, who "stored" seven 1990s Oldsmobile Cutlass Supreme convertibles in the Georgia sun, and within two years those cars turned into complete junk. The fact that he stored them in an open field he didn't actually own and near a public road didn't help either. A few of the local meth heads and kleptocrats decided to strip-mine his collection, from the radiators to the tops themselves. He had a brief time in prison in between the before and the surprise after and trust me, he looked like he had soiled his britches when he saw what happened to his personally prized Cutlasses. Then you have whoever owned this Camaro. Is it a one-of-a-kind? Nope. Just 1 of 125, and an insignificant number at that (#87). But let's open the door to this Camaro and see what we find. Oof! I don't remember this multi-colored silly string design as a '90s must-have. Wasn't this popular back in the 1980s?
