24 Hours of Le Mans live update part three

We tasked surfing journalist Rory Parker to watch this year's live stream of the 2016 24 Hours of Le Mans. What follows is an experiment to experience the world's greatest endurance race from the perspective of a motorsports novice. Parker lives in Hawaii and has an associates degree in dropping f-bombs. For Part One, click here. Part Two is here. Really hoped I'd be able to grab an hour or two of sleep before the sun rose over Le Mans. Dark dark dark, couldn't figure out what was going on. Commentators struggled at times as well. But I couldn't do it. Endurance racing is just too exciting. Grabs my attention with both fists. Screams, "watch these men DRIVE!" A neighbor invited me over for drinks. Told him, "Can't do it, gotta watch Le Mans!" Maybe not exactly. I'll admit, at times my attention wandered. I did a load of laundry. Ate some snacks. Half listened to the commentary. Threw a hump at my wife. I learned that Patrick Long, driving #88, is big brother to Kevin "Spanky" Long. Spanky's a bit of a legend in the skate world. Always weird how top notch talent can run in families like that. Kind of surprised I've never heard that before. Worked for a skate mag for a years, met Spanky a handful of times. Someone must've told me that he has an older brother who drives race cars. Dash cams at night are scary. High powered headlights in the P1s reach almost 300 meters. Cars outrun that distance easy. Seems like they're just steering into the black and hoping for the best. But that can't be the case. People'd be dropping dead let and right. Very amused by how the guys in GT are like, "Dude, stop flashing your fucking lights before you pass." But the LMP's are all, "Suck a dick! I do what I want." Top three stayed neck and neck nearly all night long. As the sun gets ready to creep back over the horizon the top three are separated by only eleven and a half seconds. Toyota 5 and 6, Porsche 2. Audi 8 is two laps behind Porsche, beleaguered 7 is dealing with constant trouble eleven laps from the front. GTE Pro sees Ferrari 82 in first, Ford 68 and 69 right behind. To win you've gotta drive perfect, build perfect. Fours cars retired so far. I'm beginning to appreciate the endurance aspect a little more fully. Only really considered the drivers at first. The mental and physical stress driving these cars at these speeds at length would inflict. But keeping the damn things running is the real deal. To win you've gotta drive perfect, build perfect.

'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).

Would you pay $17 a month to give your older Ford connectivity?

When it was first introduced in 2007, there was nothing like the original Ford Sync system, since it allowed car owners to connect and use a portable device better than anything that came before it. And because it was a brought-in/tethered and software-based system, Sync leveraged a device's connectivity and was easily updated. It took competitors awhile to catch up: Toyota Entune wasn't available until 2011, and Chevy MyLink didn't roll out until 2012. But now Ford is the one playing catchup since it stuck with the brought-in strategy while most other automakers were quicker to add connectivity via an embedded cellular modem. Ford initially installed 2G/3G modems in its small fleet of electric and plug-in electric vehicles starting in 2012 so that owners could keep tabs on charging. Embedded connectivity came to Lincoln in 2014, and Ford began adding onboard 4G LTE via Sync Connect to select cars starting with the Escape in 2015. To get more cars connected more quickly, last week the automaker rolled out its FordPass SmartLink solution that plugs into the OBD port of 2010 to 2017 model year vehicles. This lets owners retroactively get onboard Wi-Fi, set up a "geo-fence" to keep tabs on a car's location, receive vehicle health reports and allows remote engine starting and door locking/unlocking using a smartphone app, among other features. But to connect older Ford vehicles will cost owners $16.99 a month for two years, not including installation. Ford throws in 1 GB of data or a 30-day trial, whichever comes first, after which owners have to add the vehicle to their Verizon shared data plan, which supplies connectivity for SmartLink, or establish a new account. (Disclosure: Autoblog is owned by Verizon.) By comparison, GM's 4G LTE data plans start at $10 a month for 200 MB and goes up to $30 for 3 GB, and owners can also add a car to an AT&T shared-data plan. But OnStar doesn't have a separate monthly subscription for the embedded modem or an installation charge, and standard features via the RemoteLink Mobile App are free for the first five years of ownership. FCA's Uconnect Access service also uses an embedded modem to provide similar telematics features for $20 per month following a free one-year trial, while a la carte in-car Wi-Fi is offered for $10 per day, $20 per week or $35 per month.
