'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).

Here are 12 electric pickups in the works

With the unveiling of the GMC Hummer EV, the list of planned electric pickups is expanding. Legacy automakers like Ford and Chevy have theirs coming, as do startups like Tesla, Rivian and Bollinger, as well as some lesser known brands. Here are all the electric pickup trucks we know to be in the works, along with a few that are being discussed or mulled over. GMC Hummer EV The 2022 GMC HUMMER EV is a first-of-its kind supertruck develop View 40 Photos We’ve seen it now, and itÂ’s the business. The GMC Hummer EV comes out swinging with 1,000 horsepower from GMÂ’s new Ultium electric powertrain program, a wealth of off-road features, a removable roof, Super Cruise and the revival of the Hummer name. WeÂ’ll see the first ones on the road next fall. Tesla Cybertruck Tesla Cybertruck at the Petersen Museum View 14 Photos Tesla revealed the Cybertruck last year with, ahem, unique styling, a number of powertrain options and a claimed range of up to 500 miles. It has a compressed paper dash, a ramp for the bed, and “shatterproof” windows. It has already racked up hundreds of thousands of reservations. It will be built in Texas. Rivian R1T 2021 Rivian R1T View 15 Photos EV startup Rivian revealed its R1T electric pickup toward the end of 2018 with a claimed 0-60 time of 3 seconds and a towing capability of 11,000 pounds. Preproduction began in September 2020 at RivianÂ’s factory in Normal, Illinois. Bollinger Motors B2 Bollinger Motors B2 side outdoors View 31 Photos BollingerÂ’s B2 electric pickup is a Class 3 off-roader with retro styling, removable roof panels, and a unique “frunkgate” with a pass-through down the center of the vehicle. It was created with both enthusiasts and workers in mind, with features that can get it to remote places (portal axles, hydro-pneumatic suspension) and to get things done (room for 40 2x4s, equipped with eight 110-volt outlets and one 220-volt outlet). Bollinger also plans to make the B2 Chassis Cab available for fleet customization. Ford F-150 Electric Electric Ford F-150 Towing View 9 Photos WeÂ’ve known this to be in the works since early 2019. Since then, details have trickled out. Back in June, Ford announced its F-150 Electric would be coming within two years. WeÂ’ve seen it pull a million pounds worth of train and trucks, heard it will have more power than any other F-150, and seen its LED-laden front end.

Ford Police Interceptors dominate Michigan State Police testing

Once again, Ford Motor Company builds the fastest police vehicles. The Blue Oval touted the news in an official release following Michigan State Police and Los Angeles County Sheriff's Department testing. Ford did very well. Except for one acceleration metric – zero to 10 miles per hour – the Blue Oval's Taurus and Explorer-based cop cars were the quickest, with particular praise coming for the EcoBoost-powered models, which bested Chevrolet and Dodge's V8-powered variants. Dearborn's products also posted the fastest average times around MSP's vehicle dynamics course. But it wasn't all positive for Ford. The only four-cylinder in the contest, the 2.0-liter, EcoBoost Ford SSP Sedan, had both the lowest top speed, 120 mph, and the slowest acceleration figures. It was also the slowest in track testing. Ford's products also failed to match the braking and top speeds of its rivals from Detroit and Auburn Hills – the rear-drive Charger Pursuit posted the best braking stats of the entire test, while the V8-powered Chevrolet Caprice hit the highest top speed, at 155 mph. Ford did score a top speed award, among SUVs, but at 132 mph, the naturally aspirated Police Interceptor Utility had to share its award with the equally fast, rear-drive Chevrolet Tahoe. The LA County Sheriff's timing isn't publicly available, but according to Ford, the EcoBoost-powered police cars put on a similarly impressive show for cops on the West Coast. We've assembled a spreadsheet on Google Docs that offers an easy to browse comparison of the different stats assembled by the Michigan State Police, and divided the vehicles between standard V6-powered sedans, high-performance sedans (EcoBoost and V8 models), and SUVs.
