Typ the car is wound up to redline in whatever gear provides for a 1:1 ratio. Has anybody seen or heard of winding the eng up in OD ?? (dyno). On paper, top speed should be aprx 200 mph in OD. On the track/hwy/mexico, the wind resistance would kill it way before 200 mph of course. On a dyno, there is no wind resistance. This is all just theoretical bs, no practical value. I wouldn't try it myself, since the DS might start to vibrate / wobulate, tires coming apart/damaged speedo, etc. It's a more out of interest concept.
