Mechanically, the biggest improvement to the 2007 Porsche 911 Turbo is a new turbocharger that uses special materials that can handle temperatures up to 1,830 degrees Fahrenheit. With this upgrade, one turbocharger can handle exhaust gases that were split between two and can use that exhaust energy for longer than before. Of course, the new 911 Turbo has two of these units, which accounts for the fact that at 480 horsepower it’s got more power than any 911 in history. Torque is also increased from 413 lb.-ft. to 457 lb.-ft., available across a much wider range between 1,950 rpm and 5,000 rpm.
