Aluminum Driveshaft - How important is it?

As much as I enjoy a good debate, I have to break in here to say that I decided to purchase a driveshaft safety loop instead. I will need that anyway if I take my car to the drag strip (required on any street tires going faster than 13 sec., and any drag slicks running faster than 14 sec. I believe). Also, it's a part that has tons of actual data and real world proof behind it as to how it is a beneficial add-on.
If someone can show me definitively that the aluminum driveshaft is actually a smart purchase and will help my car handle the power, great, but I haven't seen any proof yet.
Also, in case anybody is wondering, I went with the Competition Engineering loop (http://www.summitracing.com/parts/CEE-3160), it's under $100 shipped and looks to me to be a well-designed part. To me, that negates the worry of the majority of consequences of a broken driveshaft. Yeah, I would have to tow the car back and throw a new driveshaft on, but it would minimize the damage to the car and keep me safe. Is it worth another $600 for a driveshaft that *may* do a better job? Meh. Time will tell.

You are. You always are. You constantly put out the same shtuff over and over when a V6 is mentioned - even when the V6 isn't being bashed. Even when your V6 faux boss isn't mentioned.
You lack perspective. You make it sound like improvement of Mustangs is something new. Or that what you do with your V6 matters to anyone else.
Back in the day, the 289 was a favorite engine. For thousands of Mustangers, it didn't matter when the 302 came out, or the 390, or what Shelby was doing with the GT500, etc, etc. It didn't matter that Pontiac, Camaro, SS396, Olds 442, Cuda were putting monster blocks in.
The 289 was a dependable engine that ran fantastic. It could be built if people wanted, but as stock it performed great for the weight of the Mustang and was great fun. Owners enjoyed their cars for what they were. Most owners are not concerned with the nth hp, lowest time slip, and high speed braggers. They bought them for personal enjoyment. Not comparison to others.
When people say you don't buy a 3.7 for performance is just silly in my opinion and other 3.7 owners would disagree. That ain't even bull crap, that's horse crap. I would agree that V6 models prior to 2011, they did not provide that much performance. Prior to 2011 if you wanted a performance Mustang you had to step up to the GT model. This is no longer the case and Ford stepped up their game with the 3.7.
In regard to the driveshaft issue. The v6 factory drive shaft is far less quality than the GT driveshaft. I purchased my one piece not for the sole purpose of traveling 140 mph. The one piece driveshaft does provide additional performance benefits besides going high speeds. I'm happy for the OP who decided to get a safety loop. For me, I'm glad I purchased my one piece aluminium driveshaft and worth it to me for the added performance it provides.

Since I’m basically worthless as a mechanic and working with wiring, the directions were a bit confusing. I had no clue what I was doing. I let my buddy who’s the pro do the install. I sat and marveled at his mad skills. I’m proud to admit I removed the engine guard all by myself along with the lower belly panel. Ha ha ha!

I don't think the performance pack v6 is limited at 112. I was able to take mines to 120 before the limiter kicked in. There wasn't a tune on it. Does anyone know if that's what they are limited to as suppose to a v6 without PP?

You never answered my question. What is a faux Boss?

Ha ha ha. What in the world does you quoting me about an entire different topic have to do with the OP's driveshaft question? What does that have to do with people purchasing the 3.7 for really good performance among other reasons? Screwy!

But with you describing yourself that way, it does not build confidence for others to take your mechanical & driving the V6 at high speed comments seriously.

You don't need to be a mechanic to understand the benefits of a one piece aluminium driveshaft. You don't need to be a skilled mechanic to understand that an aftermarket one piece aluminium driveshaft is stronger and provides a higher level of performance than a factory V6 driveshaft.
The agreed general consensus in the 3.7 community is if someone wants to travel in excess speeds of 130 plus mph then its highly recommend to install a one piece aluminum driveshaft. Its that simple! I personally don't care one way or the other if the OP or anyone purchases a one piece aluminum driveshaft. I have mine and am quite happy with my purchase. The OP asked about a one piece driveshaft question in the 10-14 V6 section and since I have one, I answered back.
The general consensus from the 3.7 community over the years is the factory driveshaft is not faulty when traveling at the governed speeds but not strong enough to handle 130 plus MPH. There was never anything that I can recall that spoke about factory driveshafts breaking because a 3.7 was supercharged and only had to do with the excess in speed over 130 mph plus.
My pony feels to ride a bit smoother, provides me with greater piece of mind at 130 plus mph runs and hopefully provides faster acceleration from a dead stop due to less rotational mass.

Love this post, My first Mustang was a 67 Fastback 2 plus 2 when I was 16. The 289 was a great motor and for a few hundred dollars for mods you had yourself a good runner at the track. One of the best motors for me also, easy to work on rebuild and soild . I agree with you, I been a Mustang fan for 40 years. I like them all and don't care if you have the fastest or the slowest. It is what makes you happy. I saw a young man at a car show with his Mustang there, it sure was in bad shape but to him maybe it was something off to a great start. As I walked passed it I thought to myself well it's a Mustang and he must be very proud of his car. To some young kid just to say I own a Mustang is very cool!
