Built for a customer that goes by the initials "AT," Switzer Performance has given this 2007 Porsche 911 Turbo a slew of upgrades in order to boost output to 900 horsepower. Custom turbochargers, new intercoolers, a high-flow air intake, flex-fuel injection system and a stainless-steel exhaust all help to give the 911 Turbo all those ponies as well as 800 pound-feet of torque.

A quarter-mile run is said to come in at just nine seconds at 150 mph, while 60-130 mph takes less than five seconds. Other upgrades include H&R lowering springs and a set of 19-inch HRE 597 RS alloys. The anonymous owner plans to race the Switzer 911 Turbo at standing mile events this year, so we'll be keeping our eyes peeled.
