Typhoon Twister

Do you dare to drive alone with the tire through a 20 meter long tube in which you accelerate more and more and then into a large funnel, which also has a diameter of 20 meters? And the next question, how many laps can you do in the funnel before the outlet swallows you up and spits you out again at the end of the following tube?
