Driveshaft for the S550 is completely different than the '11-'14 V6, as it now has a center support bearing vs slip joint on the earlier cars. That's also why you have a higher speed limiter than the earlier cars. The 3.7 was limited to just 112 mph previously, due to that goofy slip joint in the shaft. S550 is a true two piece shaft, just like what was used in the '11-'14 5.0. Much less prone to tortional deflection/vibration than the earlier junk shaft. Current speed limiter is based more on the tire type/performance rating than the shaft design.

I swear my 2011 was limited to 118 mph stock.



I did have a tune on it that removed the limiter later. Let me tell you, you did not want to go faster than 125 in that car. At that speed I could feel a strong vibration coming from under the car. Any faster and kaboom!

Yes my understanding is that it is tire limited first, then cooling system limited after. I'm nearly 100% sure that the V6 shares the same cooling package as the base GT.

Have you guys read the 2011 lightning lap by motortrend? The 2011 V6 mustang beat all its competitors on the track with the speed limiter in place:

I was surprised to see it do better than the 2010 GT. This 2015 version must be even better with the IRS and low end power.

I think you are right and in my opinion 121 is to low as I have reached this quite a few times on highway races. Most other v6 cars nowadays go above this speed. But on a positive note the ecoboost has the same top speed limit so that made me feel better.

I'm pretty sure that I read in a different post that the EB PP top speed was (141 ish?) and non-PP was less.
