Ford Mustang Bullitt, Cadillac ATS-V and profitable car companies | Autoblog Podcast #559

On this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Associate Editor Joel Stocksdale and Contributing Editor James Riswick. They talk about being behind the wheel of the 2018 Cadillac ATS-V, 2019 Ford Mustang Bullitt and 2018 Nissan Kicks. They also discuss the week's news such as Tesla and Ford both having profitable quarters, better than people were expecting. Not only that, but they talk about how the Camaro may be changing in the near future, plus the potential of Jaguar electric cars. The podcast then finishes with a Spend My Money segment in which we Autoblog editors help a reader choose a car to buy.Autoblog Podcast #559 Get The Podcast iTunes – Subscribe to the Autoblog Podcast in iTunes RSS – Add the Autoblog Podcast feed to your RSS aggregator MP3 – Download the MP3 directly Rundown 2019 Ford Mustang Bullitt 2018 Cadillac ATS-V 2018 Nissan Kicks Tesla makes a profit Ford makes a profit Chevy has changes in store for the Camaro Electric Jaguars Spend My Money Feedback Email – Podcast@Autoblog.com Review the show on iTunes Related Video: Podcasts Cadillac Chevrolet Ford Jaguar Tesla Coupe Performance cadillac ats-v ford mustang bullitt

'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).
