Porsche 911 GT2 2008

If you’re a 911 cultist concerned that the iconic Porsche may be marginalized as the company seeks to broaden its market with SUVs and —gasp!—sedans, fear not: Stuttgart’s rear-engined rocket is far from finished.
The proof of this assertion will be revealed at September’s Frankfurt motor show, when Porsche unveils the latest 911 GT2, a muscle-bound brute that makes the potent 911 Turbo seem demure by comparison.

Intercooled and force-fed by a pair of variable turbine turbochargers, the GT2’s twin-cam, 24-valve, 3.6-liter flat-six whomps up 530 horsepower at 6500 rpm—50 more than the 911 Turbo—and 502 pound-feet of torque across a plateau that ranges from 2200 to 4500 rpm.

The keys to the power increase are bigger turbos, higher boost, and a new expansion-type intake manifold that uses oscillating air to help keep the fuel-air mix cooler than in the 911 Turbo.
