The problem here is that you continue to focus on a non-issue as if it were the focal point of the whole discussion. I do not care about going past 120mph in this car. I have said it 3 times now, and you continue to talk about it.
The question is about power. Will the stock driveshaft handle the power? You don't know. Fine. Leave it at that.
But you leave immature and degrading comments like this:
along with laughing at people over and over again for no reason. Nothing in that above post has anything to do with helping anybody, only with your own need to make fun of others. People's opinions differ. Your opinions, while valid and based on reasoning, are not facts.
You do this in countless threads on here. I get it -- you get some kind of internet nerdgasm over belittling people on the web. Thank you for derailing another thread into your vacuum of mean comments and pointless observations.
/end rant

Because you were too cheap to buy a GT? Because V6 = racecar?? 
And when you wreck, and the 1 piece doesn't break away like the factory 2 piece is engineered to do so it crushes forward into the cab making mush out of your head, with the 1 piece clipping the tanks at full jounce, at least there will be a good fire to clean up the mess. Brilliant.

Then you are reading me correctly.
Sadly the web doesn't allow for TIC expressions so I often include smilies. People read how they want to read. I have zero control over you or any others and/or how people choose to read english.
Although I do think pushing a V6 past Ford's 120 limiter is risky and foolish and dangerous - to the driver and others. And the comments that simply changing to a 1 piece driveshaft somehow makes it safe (even to 140) are absolutely

And when you made idiotic replies without reading my full posts - as if I was dissing the V6, it was funny. Like the guy that threatened to hang me.
Neither of you can read and several of you have an inferiority complex about your V6. However, if you can't glean anything out of the info I provided by Ford's engineer as it relates to an Alum 1 piece vs the factory 2 piece being part of an engineered system, then your intelligence is in question like some others. Re-read your thread Title. At least I provided some real info vs the others providing nothing but internet hearsay.
Good luck in your misadventure.

To answer the OP's question, if you use the factory driveshaft be sure to buy a driveshaft safety loop. This way if it breaks, it won't mess up anything.

You realize that the new V6s are faster than your 03 Cobra right? 
I agree that I have no idea where people are doing 120mph on the street without being scared for their lives though. One bad driver, or one wrong move, and you can easily kill yourself/others. Not that it has anything to do with having a V6 Mustang though, look at what Hulk Hogan's kid did with a Supra.

I never responded to your OP did I? I responded to the idiocy of the others as to their driveshaft comments and going above 120. Just because you start a thread oh wise one does not mean it is not open to various comments as the thread unfolds. You neither control the thread or the forum. Grow up.
And when you made idiotic replies without reading my full posts - as if I was dissing the V6, it was funny. Like the guy that threatened to hang me. Neither of you can read and several of you have an inferiority complex about your V6.

So because you want to drive past 120, and assume Ford limited the speed only due to one part, you are going to ignore all the other parts of the drive train and suspension system, and drive it like a GT? Because you were too cheap to buy a GT? Because V6 = racecar??
And when you wreck, and the 1 piece doesn't break away like the factory 2 piece is engineered to do so it crushes forward into the cab making mush out of your head, with the 1 piece clipping the tanks at full jounce, at least there will be a good fire to clean up the mess. Brilliant.

The v6 mustang can reach 120mph on a track. Even Motortrend was hitting the 115mph limiter constantly when comparing the Mustang to the Hyundai Genesis coupe.
To answer the OP for what this thread was intended, I would not only recommend the driveshaft for its abilty to handle higher speeds more safely but its weight reduction which translates to a bit more power to the wheels.

When I added my alum drive shaft I felt the car wound up a bit quicker and I did notice a little bump in MPG's. If I was the op and was going to build up my car I would add the DS and loop just for the piece of mind. If the DS in a 6er will fail at high speed why wouldn't it fail if you tried to put to much HP through it?

If everyone is done pissing on each others shoes, I have a question for the OP:
Do you think you've gotten the answer to your original question yet? If so, could you please state the answer in your terms? I'm very interested in the answer.
Thank you.

Honestly it's an upgrade. May free up a couple horses and is rated for a higher speed. Maybe a little sense of security at higher speeds also. It's more of a want than a need but so are most upgrades so mod away.

for the people saying the aftermaket aluminum drive shafts for the v6's still arent able to do 130mph are stupid. american muscle sent me the drive shaft for a gt by accident when i bought mine for my v6. its exactly the same. only difference is the gt ones come with the stock V6 pinion flange. so if you buy a aluminum 1 piece drive shaft for a gt it WILL fit the v6's. youll just have a pinion flange left over. and the rear axles are the same for the v6's as they are for the 5.0's. i still have my stock speed limiter on mine because theres really no need for me to go that fast. i only got the aluminum drive shaft because there will be less drive train power loss and becuase its stronger since i plan to put a procharger on mine pretty soon.

That's a good question! I don't think I really have an answer, but I agree with the people who said that there doesn't seem to be much experience here with supercharging 3.7Ls right now, so people aren't sure, but it seems to be a piece of mind investment with minor performance benefits.
If anyone would like to add their opinion on the power handling of the stock driveshaft, please do. I don't like the idea of dropping $700 on a part if I don't have to, and I think it would help a lot of other 3.7L owners to figure it out as well. There are so many of us who bought these aluminum driveshafts out of fear of our stock one breaking without any real data to back it up. If anybody has any personal experience with blowing a driveshaft on a 3.7L or GT Mustang, please share.

Then there was this from autoblog:
Watch what happens when a Ford Mustang driveshaft fails at 135 mph
Dec 19th 2011
One individual recently learned firsthand what happens when you remove the factory's 112-mph speed limiter on the Ford Mustang V6 and proceed to accelerate to 135 mph. The vehicle lost its driveshaft, which turned itself into a spinning hunk of metal that tore into the floorpan, bashed through its interior bits and generally caused mechanical mayhem.
The term for this type of failure is "catastrophic."
So, what happened? Well, we might first point out that the driver of this particular Mustang was clearly still accelerating after the drivetrain started making suspect noises – never a good idea. We have to imagine the vehicle was vibrating like an overloaded Magic Fingers bed before things went sideways.
As it turns out, the 305-horsepower and 280-pound-feet of torque 3.7-liter V6 Mustang is built with a 2.73 rear gear ratio and a lightweight, one-piece driveshaft that's engineered to toe the line between fuel economy and performance. That driveshaft is part of the recipe that allows the coupe to yield 31 mpg highway – it simply isn't built
to handle the type of speeds the owner in the video after the jump submitted it to.
In a statement to Autoblog, Ford said that the Mustang V6 is
"the ultimate in fuel economy and performance," noting that owners looking for more speed should look toward the Mustang GT with its 412-horsepower V8, heavy-duty two-piece drive shaft and variety of rear axle ratio choices.

So I narrowed the search to 'driveshaft' and it seems the conversation moves to top speed pretty quick (which apparently is not 120 btw as one of the posters here claimed, its 112).
But as I scrolled through the threads from the search I busted up laughing. Who do I see??

Dude - you have been obsessing over this since August 2012!
Quit waffling! Make a decision! The price of a driveshaft is a pittance compared to what you'll spend building 400+ hp on that engine. Just do it and be done! lol
Life is too short, believe me...
