After we finished installing the Forza Componenti exhaust controller (http://forzacomponenti.com/) in the Ferrari F12, we were doing some acceleration runs to record the sound of the exhaust and demonstrate the new exhaust controller. NOTE: We had the owners permission.
On our final run with the valves open, the F12 slung the alternator belt! The belt was completely shredded around the alternator. The F12 has a known issue with this exact problem, so it’s not entirely a surprise but we did feel bad that it happened while on our watch. Obviously we fixed it pretty easily.
