Based on the video, it looks like the car had 1,000hp (claimed). Based on the clip of the guy standing next to the road (get behind the barrier at least), the speed seems reasonable. Although, due to speedo error, my guess is it was probably 180+ in all actuality.
Please note, I’m not congratulating him. This was insanely reckless and he deserves all the bad things that will happen to him.
