How many miles per hour does a mustang go?

Answer 1

I have a 2009 Mustang GT running a 4.6L engine, 5-speed manual transmission and a 3.73 rear end. The dealer added a Ford Racing cold air kit, and Ford Racing suspension kit. The car burns strictly premium fuel due to the performance tuning that comes with the cold air kit. So, this GT is equivalent to a bone stock Bullitt Mustang. Ford limits the top speed of the car to the maximum odometer reading. That is, 240 kmh, or 149.13 mph. The car easily achieves that speed. I try not to redline the engine. So I shift up at about 5500 rpm. Running in 4th gear to 5500 rpm takes you to about 143 mph. Shifting into 5th gear, the rpm drops to about 3600 and you quickly arrive at 4000 RPM and 149 mph, the factory set mph limit. This car handles beautifully at that speed. And, 4000 RPM is just a jog in the park for the venerable little 4.6L engine. You just want to set the cruise control and keep going. But, the other drivers might not understand. NOTE: I only do this with a perfectly maintained car on dry, empty, newly surfaced, lighted freeways, with concrete walls on both sides, when there are NO other cars. Except camaros, of course. Be careful.
