'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).

Second part of Forza Horizon 3 car list revealed early

We previously brought you the first portion of Forza Horizon 3's list of 350 cars last week, and today we're bringing you part two. Apparently Fairfax Media in Australia had the list and images early and published them on The Sydney Morning Herald's website . We say early because the publication's story reveals that Playground Games, the developer of the game, plans to make the official announcement on the Forza website this Wednesday. This set of virtual machinery brings us closer to the full list, which will continue to be revealed over the coming weeks. While this part is smaller than the first one, it still features a number of notable automobiles, including the Bugatti EB110 Super Sport, GMC Syclone and Ferrari Dino 246 GT. This list also adds more vintage Aussie machines, including the very cool 1974 Holden "Sandman" HQ panel truck. Fans of the Mad Max movies may remember Max's Sandman truck from the original film. Check out the list of new cars from The Sydney Morning Herald below and take at look their article for new images and insight on what the developers' goals were for the game. 2007 Alfa Romeo 8C Competizione 1970 AMC Rebel "The Machine" 1998 Aston Martin V8 Vantage V600 2011 Audi RS 5 Coupe 2011 BMW X5 M 1981 BMW M1 1992 Bugatti EB110 Super Sport 1970 Chevrolet Corvette ZR-1 1966 Chevrolet Nova Super Sport 2008 Dodge Viper SRT10 ACR 1969 Ferrari Dino 246 GT 1968 Ferrari 365 GTB/4 2011 Ferrari FF 1978 Ford Mustang II King Cobra 1956 Ford F-100 1991 GMC Syclone 2016 Holden Special Vehicles GTS Maloo 1951 Holden 50-2106 FX Ute 1974 Holden Sandman HQ panel van 2012 Infiniti IPL G Coupe 2015 Jaguar XFR-S 1997 Lamborghini Diablo SV 2014 Lamborghini Urus 2014 Land Rover Range Rover Supercharged 2005 Lotus Elise 111S 2013 Mazda MX-5 1990 Mercedes-Benz 190E 2.5-16 Evolution II 2013 Mercedes-Benz E 63 AMG 1999 Mitsubishi Lancer Evolution VI GSR 2008 Mitsubishi Lancer Evolution X GSR 2000 Nissan Silvia Spec-R 1977 Pontiac Firebird Trans Am 2010 Renault Megane RS 250 2008 Subaru Impreza WRX STi Related Video: News Source: The Sydney Morning HeraldImage Credit: Playground Games/Microsoft Auto News Bugatti Ford GMC Holden Technology video games forza motorsport forza horizon 3

Leveling kit now available for Chevy Colorado, but not yet for GMC Canyon

In various bits of news this year concerning the Chevrolet Colorado and GMC Canyon pickups, we kept hearing about a front leveling kit. GM Authority found a few details in early order guides in January. In February, the kit came up in relation to the Canyon's AT4 Off-Road Performance Package, and again with AEV's upgraded Colorado Bison. After three months of waiting, GMA has more info. The kit eliminates the trucks' raked stance by raising the front by one inch, using an electro-coated upper spacer and a polyurethane lower spacer in order to maintain the proper suspension geometry. Installation is a bolt-on job with low-profile nuts, but the task will require a spring compressor. Fitted properly, the kit doesn't void GM's new vehicle warranty on the Colorado. Why do we only mention the Colorado? Because for some reason, the kit isn't available for the Canyon yet as a standalone component; the GMC stays raked without one of the aforementioned option packages. For Chevy, the leveling kit is compatible with any trim in four-wheel drive except the ZR2. It cannot be installed on two-wheel-drive trucks, nor any truck wearing wheels that are 20 inches or above. The kit is available now, ordered through any Chevy dealer for $150. There is a treat in store for GMC buyers, though, but it requires spending a lot more money. GM Authority discovered that the 2021 Yukon will offer the brand's first illuminated emblem. Priced at $475 as a dealer-installed option, a backlit glow will show off the GMC logo in the grille. The brand makes the logo in red and black, it's thought the red logo will get the nod, at least at first. Only the front logo earns the spotlight, not the one on the tailgate. GMA says the tchotchke will be available on all four trims when the new full-size crossover goes on sale in a few months.
