Magnus Walker drives 911 Turbos old and new

It's been forty years now since Porsche released the original 911 Turbo. And as many things that have remained a constant, a lot has changed, too: the engine has gone from air-cooled to liquid, moved up to nearly a midships layout, and drives almost exactly double the original's output to all four wheels instead of just the back set through a seven-speed dual-clutch transmission instead of a five-speed manual. It'll also reach highway speeds about twice as fast as the original. That's progress for you, and who better to compare Porsche Turbos old and new than Magnus Walker. The outlaw of the 911 scene may not look the part, but to those in the know, he's got the last word when it comes to Porsches. After searching for some time, Walker recently got his hands on a cherry of an original 930 Turbo from 1975 – the first year it was made – and had it shipped from Australia to California to add to his collection. eGarage caught up with Walker and brought along a new 991 Turbo for juxtaposition. Fortunately it also brought along a video camera or two to document the experience, so check it out in the latest video above.

Jay Leno takes an in-depth look at a 1964 Porsche 356C restomod

Look nearly anywhere at Dr. Anand Rajani's 1964 Porsche 356C, even the engine, and you would never realize that it boasts around 50 percent more power than stock. There's no sign of any other mods to make the drive a bit more modern, either, but they're there. The car's invisible upgrades result in an amazing transformation of a car that started out pretty great to begin with, and Jay Leno can't seem to get enough of driving this beautiful, gray coupe with restorer John Willhoit. Before going for a drive, Leno takes a deep dive into the details of this Porsche's modifications, particularly of its engine. The result of all the work is a mill that looks visually stock but actually boasts a significant jump in displacement. Willhoit admits this is particular one is a fairly conservative build but output still reaches 145 horsepower and 145 pound-feet of torque. If you're worried that Jay's CNBC show might have a detrimental effect on the quality of the Jay Leno's Garage YouTube video series, then here's your answer. For vintage Porsche fans interested in the nuts and bolts of making them even better, it's hard to imagine Leno making a better clip than this one.

Jay Leno puts carbon fiber wheels to the test on a Porsche 911 GT3 RS

Jay Leno's Garage usually focuses on looking at cars new and old, speaking to their owners and then Jay taking a drive to see what he thinks. However, Leno throws his usual shtick to the curb this week to do a full product test of the carbon fiber wheels from a company called Carbon Revolution. If you're not interested in hearing about wheels for 18 minutes, don't worry. They get mounted on a Porsche and are tested back-to-back with stock wheels, and Leno takes the 911 for a track test, too.
While carbon-fiber wheels aren't exactly a new idea, Carbon Revolution's goal is to create a lightweight, one-piece product that can be mass produced. The company even claims that it already has a deal with an OEM automaker to offer them on a vehicle in a few years. The key to the technology is that it doesn't need an expensive autoclave to be made.
In the meantime, the company's carbon fiber wheels are available as an aftermarket option for about $15,000 a set, according to the video. They weigh in at about 15.5 pounds each and offer OEM-levels of stiffness, so they could cut some unsprung mass off of a performance car. Watch here as Jay and his mechanic Bernard lap Willow Springs and give their feedback about what they think of this cutting-edge technology.
