It all depends on which Mustang you are talking about. The 2011 GT500 is reputed to have a top speed of over 160 mph!
I was looking at the 2009 Ford Mustang Shelby GT 500 supplement but it doesn't show the top speed , for the 2010 version it shows that it is electronically limited to ( 155 miles per hour )
The top speed all depends on the engine because there were a few options
the governor runs the top speed to 118, but if you take that out it gets up to around 146 but it takes a while, 4th gear red lines at 120ish
about 170-180
100 to 180 try it
The 2008 Ford Mustang Bullitt has a factory speed limiter set at 151 miles per hour.
