'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).

Ford Bronco, Bronco Sport, sub-Ranger pickup and GM EVs | Autoblog Podcast #618

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor, Green, John Beltz Snyder and Road Test Editor Zac Palmer. Top of the list this week are the leaked photos of the 2021 Ford Bronco and Bronco Sport. Then they talk about the possibility of a small Ford pickup based on the Focus, as well as all the electric vehicles Snyder saw in person at GM's "EV Day." The editors have been driving the Ram Power Wagon and Hyundai Sonata, and Palmer took Autoblog's long-term Subaru Forester to New Orleans. Finally, they help a listener choose a small luxury crossover in this week's "Spend My Money" segment. then, just as they're about to wrap up the show, they learn that the 2020 New York Auto Show has been postponed due to the coronavirus outbreak.

2016 Chevrolet Camaro First Drive [w/video]

The Autoblog gang was downright stoked to learn the 2016 Chevy Camaro was next on our test-car docket. Then we found out it was the V6 model. Buzzkill. We were hoping for the snorting V8, or at least the spunky new turbo four-cylinder. The V6? Meh. We've been driving V6 Camaros for, like, six years. It's what you buy if you can't afford anything better, or so say horsepower snobs as they wrinkle their noses and cut their coffee with 93 octane. But after a week with the six-pot Camaro, we'll admit it: we were wrong. The all-new 3.6-liter V6 is strong, sounds good, and is damn fun to drive. Its 335 horsepower and 284 pound-feet of torque appear modest by modern standards, but they power the Camaro to 60 miles per hour in 5.1 seconds with the automatic, or in the case of our manual-equipped test car, 5.2 seconds. That's almost half a second quicker than the new turbo four-cylinder model. Yes, it has the same displacement as the old V6. No, it's not the same engine. Upon closer inspection, the V6's potency shouldn't come as a surprise. This engine is from General Motors' newest family of dual-overhead cam powerplants that launched in the Cadillac CTS and ATS. Yes, it has the same displacement as the old V6. No, it's not the same engine. Don't be fooled, and don't underestimate it at stoplights. The strapping V6 is unsuspectingly good, but it's just one of many improvements for the sixth-generation Camaro. Chevy's coupe is lighter, faster, and more modern looking inside and out. It starts with a rear-wheel-drive chassis donated from the Cadillac ATS, though about 70 percent of the components are unique to the Camaro. The 2016 model is about two inches shorter in length (thanks to a shorter wheelbase) and about an inch has been removed from height and width compared to the 2015 model. These lighter underpinnings jumpstarted the Camaro's weight-loss plan, and thanks to extensive use of aluminum, the V6 with the new eight-speed automatic transmission weighs 3,435 pounds – 294 less than its predecessor (the manual-transmission V6 Camaro weighs 3,448 pounds). The V8, meanwhile, sheds 223 pounds. One by one, these elements would merely enhance how the Camaro drives, but taken collectively, they invigorate the new model. It feels much more confident and agile in all circumstances. Put simply, it's a sportier car.
