I believe this info was given to us already. I specifically remember seeing that it will be 155 MPH on the 5.0 and PP EB. The base EB and V6 are quite a bit less. Top speed is less on the 5.0 than you would think given its power/weight numbers because of cooling issues, if I remember correctly.

The GT is limited to 155mph, the V6 and non-PP Ecoboost is limited to 121(124?)mph.

Without the limiter top speed would be limited to gear ratios. For the 5.0 and 3.73 gears, you will hit the rev limiter in 5th at around 150mph. Shifting into 6th will yield very little if any more acceleration. Top speed with 27" tires and 3.31 gears is around 175mph at the top of 5th.

...unless it has a 2pc driveshaft.

What is this in reference to? Most modern cars have two-piece driveshafts including Mercedes AMG and BMW M-cars.

I'm guessing the reference was to the 2011-2014 Mustang V6's and their one-piece driveshaft. Everybody was mystified why the car had a 113 mph governor... Until people took off the governor and realized the the drive shaft exploded around 130 mph. Literally exploded; shrapnel through the center console.

Top speeds are regulated by insurance...

Get a tune and remove the artificial limiter.

I'm 99% sure that top speeds are largely dictated by the recommended OEM tire v-max, though I wouldn't doubt there being a large number of exceptions to the rule.

I've heard as much. Plus, cars may be designed with low amounts of drag but that doesn't mean their designed with adequate engine ducting/cooling to withstand the excessive RPM's it takes to wind a car that fast for that long. (Even a GT is going to take a bit to get to 155) I'm not very educated about this, but I'd guess that the GT and EB4 PP are designed with better engine cooling as well as the higher speed-rated tires.

How do you explain my 202MPH GT500? My insurance runs the same as my 155MPH limited Boss.

I just ignored that bit of "insider" info lol

non-PP Ecoboost is limited to 121(124?)mph.

Have this been confirmed? Disappointing if true.

Performance Pack Ecoboost Mustangs have a 149mph limiter. (previously reported as 145, however Car and Driver published 149mph)
