It appears that the full circuit may exist in vp3 - the blocked exit and entrance suggest this (though as you pass between them a racing barrier is clearly visible at the top of the hill which seems to be a parallel track, which according to the following track plan shouldn't be there):

I wonder if the Monkeys have any plans to open the full circuit, it looks like it would extend the track by at least half and from watching real videos on youtube it looks like fun.
