Porsche’s glorious flat six engine is known for its sonorous high-RPM note, and when the engine is unmuffled, it only sounds better, but is also much louder. Often times, at big racing events, the Porsche competitors are driving the loudest cars on track. There are some Porsche engines that are even louder than that, however, as the 928’s V8 can make a huge rumble, and Porsche’s Formula 1 flat-eight is louder still. The loudest thing Porsche has in the collection, though, is allegedly the 1974 911 Turbo RSR.
At 138 decibels, the Turbo RSR is nearly as loud as a small jet engine aircraft taking off. It’s loud enough to cause hearing damage after more than 30 seconds of exposure. It’s not just a weapon on the track, but an attack on the senses. Literally.
Across the top five, Porsche’s assembled a few really rare and really exciting race car models. Obviously, without the need for mufflers, race cars are quite loud at the race track, but I can imagine they feel quite a bit louder standing feet away from the loud end while in a quiet museum building. The premise of this video is absurd, but incredible at the same time. You can tell these two are just having a blast doing their job.
