I am sure you are referring to driving 118 on a track and not public roads, right? (various forum members and the owner do not condone triple digit speeds on public roads!)
I hit 115 on the track at my last DE and that's the fastest I've driven my box. Not the fastest I've driven a car though... that would be 162 mph in a Carrera on the autobahn.
