Hi, I drive an 07 auto V6 and Im buying an xcal 3 from bama chips very soon but im nervous about what could potentially happen if i ever get over 120 mph since the tuner will take the speed limiter off. My goal is to have my car rated at about 140 mph.
I've been looking into drive shafts and have come across both the aluminums for around 5 or 600 and I have also seen something called a front drive shaft loop which i don't really understand... Sutton High Performance - Products
1. Will the drive shaft loop make my stock drive shaft able to
withstand higher speeds? If so up to what speed approximately?
2. How fast could an aluminum driveshaft go before expiriencing
problems?
3. Is there any kind of cheap gt takeoff drive shaft that is
compatible with my v6?
A safty loop is desinged to catch the drive shaft if it fails(break) so that it does'nt blast thru the floor board. And you should discourage yourself from buying anything cheap.
My X3 as delivered did not remove the limiter. However, it has an option to change the limiter which I did not do for safety reasons. Those concerns were tires, driveshaft and antisway bar.
Since installing the combo I installed GT takeoff wheels with the standard V-Speed rated tires. I installed a rear GT anitsway bar for added stability. But, I have not replaced the driveshaft and will keep the stock RPM and Speed limiters as-is for now.
The shaft loop you ask about is a safety feature to contain the drive shaft if it shells out. Wthout a loop you risk some costly lateral damage to everything near it. As far as I know you can install a GT takeoff and it is capable of the speed you mention.
Have you taken advantage of other mods to maximize a tune such as a CAI and exhaust improvements?

The driveshaft on our V6 are know to fail above 120 mph and thats the cause for the speed limiter. If you take off the limiter and it fails, your warrenty will not cover it since your own stupidity caused the trouble. An aluminum driveshaft is the best option as it will sustain just about any speed you can get out of the v6. It also weighs only 14ibs which is a plus. The safety loop is just that, safety for if it does fail. Without it during a fail at that speed, you would be in for a ride. Look for tires that are Z rated, it means that they can go fast. The suspension is also a worry at that high of a speed, maybe think of some gt takeoff sway bars and some lowering springs. Maybe a life insurence policy too.

Follow his advice specially the last part. Other than that your good to go with aluminum ds because its durability. My x3 also didnt take the limited off however you can do it manualy

sorry, just clarifying, are you saying that it is possible to add or remove speed and rev limiters just by changingthe user controlled options? thats pretty cool, i thought it had to be done by the tuner.
I don't think you'll necessarily need Z-rated tires, that would be pretty impressive if you could get your sixer going that fast. V rated tires would be enough, I would think. And an aluminum driveshaft would do the job, I wouldnt suggest going with anything cheaper.
Just my .02...

As long as your tuner has enabled the adjustable options in the device you'll be able to make those adjustments...

Y rated tires should be good up to 149mph so like edward said those should be good enough as the car probably wont get that up to that speed anyway BUT if you do go with Z's they should be good up to about 165-168. Be careful
I've had my V6 pegged over 120 several times. At around 115+ the vehicle gets a little 'floaty'...okay, a lot floaty. A change in the front fascia would probably correct that but stock it develops a lot of lift at the front end and feels like there's only about 50lbs of weight on the tires.
A bone stock V6 with the limiter disabled will top out at 147mph. I can't seem to find the article now but a fellow took one on the autobahn a couple yrs ago and got it up to that speed. From 135-147 it took a long time (several minutes) to get it that last little bit.

Wow, 147, thats impressive. I didnt imagine it would get up that high. Mine in all its glory will hit 120 about halfway through fourth though so I guess its possible.

Some of the floating is the stock tires on the V6. When I installed the 17" rims with V Speed the footing was more firm and some of that handling you describe disappeared. Also, the antisway bar helps handling at higher speeds, not just the cornering.
I'm doubtfull that a bone-stock, delimited V6 will do 147. If you ever find out who I would call him out on it and have them prove it. What did he do put tick-marks on the speedo after the 120 marking ran out?
