Radical SR8 LM Brutal Loud Sound!!

I have filmed a friend's Radical RS8 LM being tested at the Monza racetrack. Actually, it's the fastest road legal car at the Nurburgring track with a lap time of 6:48. The video shows many accelerations and very high speed fly bys with also a little backfire. In the main straight the top speed they reached was 302km/h.
