Chevy donates first 2015 COPO Camaro for wounded vets

Want to get your hands on a new COPO Camaro? Only 69 will be made this year before it's phased out ahead of the next Camaro's arrival. And the very first one will be auctioned off this weekend in Palm Beach. That's where Barrett-Jackson will be selling the hand-built drag-racer with the serial number 2015COPO001. The vehicle is being donated by Chevy, with 100 percent of the proceeds benefiting the Achilles Freedom Team of Wounded Veterans, a charitable organization that helps disabled athletes, especially veterans of the armed services. Introduced last fall at SEMA, the 2015 COPO Camaro is built specifically for drag racing with a 350-cubic-inch LSX racing engine with a 2.9-liter Whipple supercharger. It's got 555 horsepower, a three-speed automatic transmission (it's a drag machine, not a circuit racer after all), all the requisite safety equipment, special suspension setup, unique livery and a quarter-mile time in the mid-eights. Look for this unique example to cross the auction block at around 5 PM on Friday, April 18, when we hope it will raise a princely sum for a good cause. 2015 COPO Camaro No. 1 Sale to Benefit Disabled Veterans Top bid from Barrett-Jackson goes to Achilles Freedom Team of Wounded Veterans DETROIT – Chevrolet is selling the first 2015 COPO Camaro race car to raise money for Achilles Freedom Team of Wounded Veterans, which helps wounded veterans participate in marathons and share their success within a supportive community including their families. The hand-built car carries serial number 2015COPO001. It will be sold on Saturday, April 18, at the Barrett-Jackson Palm Beach auction, with 100 percent of the winning bid going to Achilles Freedom Team of Wounded Veterans, a non-profit organization that helps disabled athletes, including veterans, gain access to races, equipment, and training dedicated to improve their physical abilities. "This sale gives the highest bidder the opportunity to buy the first of only 69 factory-assembled 2015 COPO Camaro race cars, the final year of the fifth-generation Camaro," said Jim Campbell, U.S. vice president of Performance Vehicles and Motorsports. "Chevrolet is excited to offer this milestone Camaro to help a very worthy organization." Chevrolet introduced 2015 COPO Camaro No. 001 last fall at the SEMA Show in Las Vegas, and it has been featured in Chevrolet Performance advertising and other marketing initiatives.

'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).

1983 Motorweek showdown pits Porsche 928S vs. Chevy Camaro Z28

Last month, Motor Trend threw the Camaro Z/28 and Porsche 911 GT3 into the bear pit and let them fight it out. Way back in 1983, MotorWeek had the same idea, comparing the Camaro Z/28 to the Porsche 928S. At the time, the Camaro was America's best selling sports coupe, the 928S was Porsche's top-of-the-line model that also had the highest top speed of any car sold here. And the price differential was even more stark then: $13,600 for the Camaro, $45,000 for the Porsche. That put the Z/28's cast-iron, 5.0-liter V8 with 190 horsepower and 240 pound-feet of torque against the all-aluminum 4.7-liter V8 with 234 hp and 263 lb-ft in the 928S. Even with that and the Camaro being 14 inches longer than the Porsche, the American was a surprising 40 pounds lighter than the German. The show took them to Summit Point Raceway in West Virginia to see how close a relative performance bargain could hang with a the German GT. Both had five-speed manual transmissions, but the high-speed corners and tight sections of Summit Point would test other handling variables, including the "bone-rattling" Camaro's solid rear axle and disc and drum brake setup vis-a-vis the four-wheel disc brakes and independent suspension on the "firm-but-smooth" Porsche. Paradoxically, the larger disparity 22 years ago resulted in a closer result. Check out the video to see how the Summit was won.
