I'm not sure if this is WR tie since some might have done 9"07 and not sure about 9"06 since no one seems to have done it in TMN.
I did this time in TMN hence the look of the track that is different from the TMU version.
WR there is a 9"03 because of different physics.
My 9"07 is the only one I got, and it's actually extremely hard to get this with keyboard. The first trick to do is the start trick, land on the road earlier than normal, to catch a little speedboost. Here I managed to get it almost perfectly.
The loop. The trickiest part of the map. So random. So hard to master. For unknown reasons, you win/lose speed. It's possible to make micro speedslides but wait... skids are nearly invisible so you don't see. I think I managed to get a little more speed as I wasn't even able to reproduce it.
The end : try to not touch the green bar, if you don't want to have bugs such as rammstein's.
However, if you are lucky enough, it miiiight be possible to do a little speedslide, but wait... will it be faster ? I don't think so because the car won't be straighten since the path is quite short.
Is a 9"06 possible ? Humanely impossible for keybaord players I think... but there are things that could be possible with keyboard and not with pad, so no one knows what could be possible.
I was never able to reproduce my run at all, the results were always 9"08's.
Notice that I couldn't have access to 2006 WRs from wayback machine, only from 2007.
Thanks for watching !
