Electronically limited to around 110-113MPH. After those speeds the stock driveshaft might get a little screwy and shatter. Although if you took the governor off I've heard they will do 130-140mph! With a new Driveshaft, Coldair intake and a Tuner you should also see improvements.
The mustang v6's top speed is 160.
I have a V6 2000 mustang the top speed I ever hit it was 120-125mph. Its only has a BBK Cold Intake
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
115... limiter kicks in
The 2009 Ford Mustang has a V6 engine.
