Porsche 917K racing at high speeds! (brutal flat-12 sound)
The 917 Kurzheck is very rare and very expensive. However, on a racetrack like Spa-Francorchamps you just gotta do what you gotta do, right? Drive it like you stole it! This was recorded during the Classic Endurance Racing 1 (one hour race) at the 2019 Spa Classic event.
