Let’s take a moment to chew on the Porsche 911 GT3’s top speed, shall we? The GT3, with its 475 hp naturally aspirated engine, was supposed to be ultimate athlete(*1) of the current 911 range, so outright velocity is not necessarily its top asset. Nonetheless, its official top speed sits at 315 km/h (195.7 mph), only 3 km/h below that of the 560 hp Turbo S, currently the most powerful member(*2) of the 911 line-up.
Back in August, we showed you a bone stock 911 Turbo S doing 333 km/h (207 mph). Even if we are to take into account a speedometer error of, say, 7 km/h (4 mph), we’re still left with a super-impressive value. Drag varies with the square of velocity, so at this level of speed, every extra km/h is an important effort.
We’re not quite sure what the 911 GT3 can do in the real world when in factory stock condition, but we’re here to show you what an example of the rear-engine coupe achieved after being gifted with an aftermarket exhaust system.
As you’ll be able to see in the footage below, the slightly touched 911 GT3’s speedo went all the way up to 334 km/h (207.5 mph), a value that puts this track specialist well into the 200 mph club. For the record, the car had been fitted with an iPE Innotech Performance exhaust.
*1 Porsche has been spied testing the 911 GT3 RS, so it’s only a matter of time until the range receives a new king of the sports. The 911 GT3 RS was also leaked via a scale model.
*2 Zuffenhausen should release a 911 GT2 (RS), basically a Turbo with more power and rear-wheel drive. However, while this would top the Turbo S’ output, it’s not clear whether the model will actually arrive or not.
In his quest to bring you the most impressive automotive creations, Andrei relies on learning as a superpower. There's quite a bit of room in the garage that is this aficionado's heart, so factory-condition classics and widebody contraptions with turbos poking through the hood can peacefully coexist.
