Callaway debuts its new C7 Stingray at National Corvette Museum

Callaway showed off its first tuned version of the 2014 Corvette Stingray at the National Corvette Museum last week, giving the rampant enthusiasts of America's sports car a look at the roughly 620-horsepower, supercharged rocket.
Unlike the Corvette SC610 we showed you back in January, this Stingray packs a fair bit more oomph. Horsepower is only up ten ponies, but torque has jumped from 556 pound-feet to "at least" 600 pound-feet. Neither horsepower nor torque is official quite yet, although Callaway is expecting to know just what its creation can do once testing and validation is completed later this month.
The 6.2-liter, supercharged V8 now boasts a new, three-element intercooler, which Callaway claims only allowed the inlet air temperature to increase by ten degrees Fahrenheit during dyno runs. Previous designs saw a 35-degree-Fahrenheit jump. The exhaust system has also been fettled with, and now is even less restrictive.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

Burt Reynolds' vehicles up for auction at Barrett-Jackson

Burt Reynolds' influence on car culture cannot be overstated. Be it "Smokey and the Bandit" or "Cannonball Run," his films inspired a generation of car enthusiasts. He died a few weeks back from cardiac arrest at age 82. This weekend, four vehicles from Reynolds' personal collection — three Pontiacs and a Chevy — will go up for auction at Barrett-Jackson in Las Vegas. It seems Reynolds had plans to sell the cars before he passed. He even filmed a short teaser for the auction and planned to attend the event himself. Three of the cars are Pontiac Trans Ams. Two are re-creations of the cars he drove in "Bandit" and the film "Hooper." Both are 1978 models. The third Trans Am is from 1984 and was used to promote Reynolds' USFL team, the Tampa Bay Bandits. The fourth vehicle is a 1978 Chevy R30 pickup truck. It's styled like the truck he drove in "Cannonball Run." None of the vehicles were actually used in the movies. But they were registered in his name, making them far more legitimate than some other movie-inspired clones. It's unclear how many Bandit Trans Ams Reynolds has owned over the years. Another car connected to him sold for $450,000 back in 2014. His death is sure to drive the price of these new cars even higher.
