Speeds upwards of 2050 have been reached on this jump, but around 2000 speed should be adequate for passing it.
To gain maximum speed, make the long right turn at the beginning of the run
near the outer perimeter of the track, to maximize the distance travelled.
You'll notice in the video that my line is so far out that I even come close to hitting the wall/corner right before the tube. You
should try to do the same. Also, make sure your keyboard allows you to have forward and sprint pressed down while you are powersliding.
If that's not the case, you almost certainly won't make it through the gaps at the end.
