I waded through all the pages briefly to make some investigations and here is some additional info:
-the track is 4000 meters long 100 meters wide
-entry fee is 150 euro
-They intend to flag away A pair of drivers at the start to speed up the event
-Motobikes are also allowed if they can reach a theoretical topspeed of 300+ km/hr
-maximum starting field is 40 cars ( don`t know about the bikes)
-only a maximum of 100 spectators are allowed to unload the work schedule of the volunteers and officials
the odd thing is that the organisers are envisioning monitoring the E.T. of all the racers runs instead of the measured topspeed at the end of the track, but they are already persuaded by several people to include topspeed measurement aswell.
Seems logical to me. All the other high speed events in the world do this too.
The discussion on the german forum is somewhat hilaric. Up until now most interest is coming from the dragracing crowd, but they lack the aerodynamics, proper final drive gears or engine reliability to survive through the rounds.
Also most of them have never done this before and already the lack of confidence is seeping through on the forum. Their initial enthusiasm is somewhat overshadowed by the realisation how fast 200+ mph really is, especially after seeing some of the videos posted by some members showing cars getting horribly out of shape at speed on similar events ( Texas MAXTON mile, etc)
Here a list with results from a similar event held in the Soviet Union:
