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.

Check out the official 2013 Trans Am Hurst Edition commercial

The Poncho is dead. Long live the Poncho. Like certain other reoccurring personal maladies, the aftermarket community simply can't let the Trans Am go without another flare up. The guys at Trans Am Depot have worked up a quick commercial for their newest creation: The 2013 Trans Am Hurst Edition, and it watches pretty much like you'd expect it to. The footage is comprised of just about every TA male fantasy you can conceive of, from Daisy Dukes and white tank tops to tramp stamps, bikinis and ice cream cones. There simply aren't words for what you'll see below.
Of course, we like our T-Tops as much as the next guy. If you like what you see in the videos, you can pick up your very own TA by heading over to the Trans Am Depot site. The guys even have Chevrolet Camaro-based versions of the Pontiac GTO if the '77 TA treatment is too much for your tastes. Enjoy, but don't say we didn't warn you.

Feds open investigation into Chevy Express, Ford Freestar rust issues

'Tis the season... for road salt. And with that, comes rust. And what does rust bring? Well, for Ford and General Motors, a National Highway Traffic Safety Administration investigation. According to The Detroit News, NHTSA is looking into potential recalls issues with Chevrolet Express vans and Ford Freestar minivans.
The feds have received five complaints that rust has caused leaking fuel filler pipes on 2003 Express vans. Separately, seven complaints have been filed over excessive rust in the rear wheel wells of 2004 Ford Freestar and Mercury Monterey minivans. The Freestar and Monterey went out of production in 2007. Neither issue has resulted in any crashes or injuries, according to the report.
