Viper ACR Extreme vs Porsche 918 at Spa Francorchamps track

With my friend in his 918. I had just started on track and the 918 was just behind me. He then appears about 35 seconds into the video. Ok its not a straight dual as there was lots of traffic and so we couldn't do a proper head to head, however its clear to see the 918's superior fire power to overtake when it has a straight in front of it. At points I would have been able to close the gap substantially were it not for the traffic, but it was what it was. Anyway a bit of fun.
