Porsche 911 GT3 Demo by Echo Collective published on 2015-03-16T15:10:52Z The Porsche 911 GT3 is not a typical race car. With engine, transmission, air intake and exhaust all situated in the rear of the vehicle under a large wing, this pure driving machine has sonic characteristics very different from many familiar racing vehicles. Its exhaust note is deep and throaty and the transmission is snappy at speed. The Porsche 911 GT3 library is a series of recordings that were made on a track just outside of Houston on media day for the Effort race team. These are 2014 Porsche 911 GT3 Rs that race on the Pirelli World Challenge series. Each car has a naturally aspirated, water cooled, four valve 4.0 liter flat six cylinder Porsche engine. These cars create 500 horse power from the factory and race with E10 fuel. The transmission is a Porsche six gear racing box with sequential shift mechanism. Genre racing
