'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 trucks and SUVs for brake pedal problem

The Basics: General Motors will recall over 473,000 North American examples of the 2015-2016 Chevrolet Silverado HD, GMC Sierra HD, and police pursuit versions of the Chevy Tahoe. These include 426,573 vehicles in the US and 46,837 in Canada, according to Reuters. The Problem: The brake pivot nut can loosen over time, which can render the pedal inoperative. This would be a danger to drivers trying to stop the vehicles. In some cases, the "Service Engine Soon" light might come on. Injuries/Deaths: None reported. The Fix: Dealers will inspect the pivot bolt, and if necessary they will apply adhesive to it and reinstall the part with increased torque. If You Own One: "We expect to start customer notifications shortly," GM spokesperson Tom Wilkinson told Autoblog.

If the brake pedal becomes loose or inoperative, it could interfere with the accelerator pedal, and/or the driver may be unable to safely stop the vehicle through application of the brake pedal, potentially affecting stopping distances and increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will inspect the pivot bolt installation to determine whether the vehicle has already received the production remedy. If not, the dealer will add adhesive to the nut, and reinstall the nut at an increased torque. Note: This condition may result in the "Service Engine Soon" light illuminating, and brake lights may stay on longer than expected.

2023 Detroit Auto Show Mega Photo Gallery: All the new reveals and first looks

The 2023 Detroit Auto Show didn’t play host to a lot of reveals, but on top of the new cars that were revealed there, automakers brought a whole bunch of cars we havenÂ’t seen in person yet. In a show of home strength, all the big reveals came from the hometown Big Three, with Ford, GM and Stellantis playing host to the most important unveilings. We took Huntington Place by storm to capture all of the new cars and sights to see in Detroit, and you can see everything we did in the series of galleries below. Interesting special editions like the 2024 Ford F-150 Lightning Platinum Black Edition and the 2024 Chevrolet Camaro CollectorÂ’s Edition found some floor space alongside bigger debuts like the refreshed gasoline-powered F-150 and 2024 Jeep Gladiator with its new interior. If you wanted to see it all yourself, make sure you check out our guide on how to attend the public show days.
