The 991 version of the Porsche 911 GT3, particularly in RS guise, is one of our favorite cars to listen to. It sounds absolutely amazing, but as some regular buyers of certain performance cars have learned, new emissions regulations can sometimes mean new filters in the exhaust system, which often translates to a poorer sound. However, Porsches usually sound excellent, despite Californian lawmakers almost calling the manual 992 GT3 illegal because of the noise it generates. We think it sounds fantastic and hearing it rev to its 9,000 rpm redline is something we could do all day. Thankfully, a new video for Biesse Racing allows us to do just that.
The first thing we notice about this dyno facility is that it appears to have been built specifically for Porsches, or at least for mid- and rear-engine cars as a whole. The example on the rollers is a brand new and totally stock 992 GT3, and the testing was conducted in ambient temperatures of around 95 degrees, so it was definitely not an ideal day for a dyno run. Nevertheless, on pump gas, the GT3 achieved 500 hp and 329 lb-ft of torque. This figure was achieved with 100RON fuel, but it's still darn close to the quoted figures of 502 hp and 346 lb-ft of torque.
It's unclear what Biesse Racing's goals for the car are, but the company says it will soon do more testing "in better conditions." Scrolling down the tuner's Facebook feed, we see that the outfit has just finished fitting a full exhaust system to a 992 Carrera 4S, so we're hopeful that the GT3 is about to get the same sort of treatment. If so, there'll surely be a video to follow, and we look forward to bringing that to you. In the meantime, take a look at one of our earlier stories on how NOT to fit an aftermarket exhaust to a Porsche.
