i thought the same thing when i put in my exhaust system, but saw a seam.

even if it is a single piece, the same principle holds true, unless it is shortened or lightened....physics arent selective. Too many individuals in the thread have equated speed with MPH and a nanny mentality, its RPM and gear multiplication. Compound that with larger tires and wheels and shorter ratios, and driveline stress increases.

I just can't hold it in any longer!

In my opinion SultanGris is an accident just waiting to happen and what worries me most is that you'll probablly take some innocent family with you when you go. I read these forums almost daily and you, YOUNG MAN definately have some problems. Here are just a few of your remarks in the last couple of months...

"Keep your physics lesson to yourself, we already know, at least I do. You have to be aware of your surroundings and know your stopping distance and its not that damn hard to do. 96 is the lowest limit Ive ever seen on a vehicle, most are at 100 or 105. Maybe you never go over 70 and thats great, just stay in the right lane and out of the way of everyone who knows how to drive."
　
"Ill drive 98 if I damn well want to. This is America, we fight and die for our freedoms, we dont want jackasses telling us what to do and we are willing to go fight and possibly die to protect those rights, if you dont like it go back to england and drive a clown car, otherwise kindly STFU and keep your asinine opinions to yourself, thanks."
　
"Im no Ken Block, but im no average moron off the street either. I like going out and pushing my vehicle to the limits in a safe environment, it helps you be prepared in emergencies so you know what slides where and how much instinctively if it ever occurs accidentally."
　
"Its not that difficult or as dangerous as you might think if you know what your doing."
　
"There was a guy in a diff thread that said he removed his and the stock truck easily went 130, though he wasnt gonna do it again, haha! I plan on removing my limiter, you sometimes do need to go faster, plus you cant be having chevys that govern at 100 passing ya on the freeways cause youre stuck at 96, thats just BS, Ill be passing them, lol!"
　
"yea, and up here in ND they are 75! lol, its a very low limit by normal peoples standards. If you wanna set it to that or lower use the mykey feature, I personally want no limit on mine when Im driving it, Im a big boy, I dont need a nanny, lol!"
　
"People dont have to take any action when I pass them, you think I wanna get rear ended by some idiot that cant drive? No I dont, I actually know how to drive very well so I dont cut in front of people and slam on the brakes, if I cut in front of someone Im making sure I have plenty of room and Im on the throttle and gone before they even know what happened, haha! Im not leaving a trail of wreckage in my wake, I know how to drive and dont put myself or anyone else at risk when I drive agressivly and pass people. I can understand why people of lesser skill levels dont understand what it is to be a good driver, but you all can trust me, I am an excellent driver. Always being aware of all surroundings when driving is a good place to start, not eating a big mac and talking on the phone, haha! "
　
"The difference is that I dont think I am a good driver, I KNOW I am and in over 15 years of driving have never caused an accident. I do know plenty of people who think they are good drivers but clearly arent. You should always use your blinker when changing lanes!"
　
"I can understand why people of lesser skill levels dont understand what it is to be a good driver, but you all can trust me, I am an excellent driver." (one of my favorites), reminds me of the Rain Man movie. http://www.hark.com/clips/nbmlltzpgt-excellent-driver
　
"speed is not the contributing factor in most accidents. Its perfectly safe to drive fast if you know what youre doing. However driving to fast for conditions or in heavy traffic and messing with the radio or phone while driving fast can cause accidents, but ultimately its not the speed that cause it, its the distraction. The faster you are going the harder you crash. Obviously its not a good idea to drive faster than conditions allow, and lots of people dont understand what those conditions are sadly so its idiot drivers that give speeding a bad name."

"yea the traction control would kick in, but it wears out your brakes faster and slows ya down. Its much cooler to take off from the line and break it loose and go sideways for a bit. Scares the crap out of the people in the other lane, haha!"

"I find that lots of people are driving slower these days just to save gas presumably. I pass nearly everyone."
　
"96 is way to slow! seriously, they always used to cut ya off at 100 or 105 which is ridiculous too, but now its 96? really? programmer here I come!"

I couldn't find the replies about driving 70 MPH on snow covered roads but I think ya'll get my point.

SultanGris I know you're going to come back hard at me (that's just the natural thing to do) but that's ok, I can take it. I've been driving longer than you have been alive and I hope you live long enough to see where I'm coming from. I'm just glad that you're far enough away from me that I don't have to be concerned about you taking me or a member of my family out with you.

I don't buy the physics theory. The truck drive trains turn at slower rpm than most cars, and have improved greatly over the decades. Limiters are all about liability. Many big transport trucks are speed restricted to protect company images from jackass drivers, many cars are restricted to tire ratings, motorcycle top speeds limited by companies to stop the speed war and insurance backlash, and on and on.
Like I said I have a 400 hp 71 GMC one ton, nothing high tech but does 145 mph like a dream. I'm sure a new F150 2wdr 6.2 411 hp truck could easily do the same without a problem, equipped with proper tires etc.
That said buying a truck to crack the century mark is a poor and immature buying decision. You want to preserve your right to speed. Take it to the race track dudes.
Driving is not a right. It is a privilege. Explain your rights to the officer arresting you and the judge taking away your "right" to drive excessive speeds on PUBLIC roads.

I appreciate the fan club Seriously though I will guarantee you my driving skills are well above average and unless you are an over the road trucker I have logged more miles driving than you have. Im 31 years old and i have been driving since I was 6 years old. I can see how you would think this as when you get older your reflexes slow down, but I find it hard to believe you never thought you had enough control of your vehicle when younger to go over 100 MPH, its really not that fast by todays standards. Course maybe back in your hayday vehicles were not capable of such speeds. Granted my driving back then consisted of turning the key on when I wanted to go and turning it off when I wanted to stop, haha! I grew up on a farm in rural ND, not much to do around here for fun besides drive. We were always our rip roaring around sliding around corners both on gravel roads and snowy icy pavement, doing donuts, reverse donuts with fwd cars, ebrake slides, 4x4 sliding and pretty much anything else you can think of me and my friends did. It gives you a pretty good handle on what your vehicle can and cannot physically do and also helps you know whats gonna happen and how to react instinctively if you are put in such a situation accidentally. Ive said it before and Ill say it again, Im at no time putting anyone else at risk and I dont drive like that when there is other traffic present, I dont think you people realize just how unpopulated ND is, according to the 2009 census the population was 646,844. There are plenty of places and opportunities to safely do such maneuvers. Im not talking about or advocating driving 100+ down a residential street where your house is located, nor am I talking about driving 100+ for extended periods of time. like I said before its the lowest limit on a vehicle Ive ever seen and even though I dont plan on driving 120MPH everywhere I go I want the ability to do so if the need ever arises, understand? Freeways are built for speed, if youre scared of someone going over 70, stay the **** off them and let the people that know how to drive have them, it will lighten up traffic and allow us to go even faster if you get rid of the blue hairs that drive 30 under the limit and leave their blinkers on for 5 miles at a time. I have never once been on a freeway or interstate where the average speed of traffic wasnt 5-10 MPH over the posted limit, sure some people go the limit or slower, and more often than not get in everyone elses way, and some people go well above 10 over, its not your business to tell others how to drive and if youre scared to be on the roads with fast drivers then by all means stay off of them, get someone younger to drive you or take a bus. I dont plan on doing 4x4 slides and driving over 100mph when i get to an advanced age as I know your reflexes get slow and would no longer be able to safely preform such maneuvers, but while Im still safely able to I intend to have fun in controlled environments damnit! So mind your own damn business you nosy old man, I aint walking on your lawn! Haha, couldnt resist that last one, but you said you could take it.

SultanGris

I agree, based on my unbalanced two piece driveshaft in my 75 thats been going 70 for 40K miles with no ill effects other than vibration, exceeding 100 for short periods of time isnt gonna make your properly balanced drive shaft explode. I, like pretty much everyone else in this thread ive seen didnt buy a truck to drive 130 down the road everyday, we just want to be able to do so if the need arises without being electronically nanny limited in a vehicle we paid lots of money for, but we get to spend more money and buy a programmer, lol!

BassAckwards

Oh I totally understand and agree with you in fact when I got my tuner I turned my speed limiter down to 92 since my 33"s are only good to 99

First of all I really don't care if you walk on my lawn. Second of all you havn't been driving long enough to have logged more miles than me (I can't give you credit for those miles sitting on your dad's lap when you were 6 or 7 years old), I once let my 6 year old grandson fly my Cessna 172 from the right seat for a while but he would honestly tell you today that he can't fly an airplane. Third thing, you've probablly forgot about the muscle cars of the 60's and early 70's (whoops I forgot.. you wasn't even born yet) anyway they had a bunch of horse power and would go really fast. Forth thing, I wouldn't trust any other driver to take me anywhere except maybe one of my kids who I taught to drive and all 3 of them have more experience than you do. Give us all a break and quit bragging about what an excellent driver you are.

Its all about what the critical RPM the driveshaft is designed for. When I designed clutches for manual transmissions for a ford supplier (we did the mustangs) we designed for a 2x rpm safety factor based on engine redline.

For a fact when we were designing the 2005 mustangs the v6 prototypes we had had 105-110mph limiters (i dont remember precisely offhand) but the reason why (from the test engineers mouth) was that at that speed we passed the critical rpm for the driveshaft in mass produced tolerances and any speed above that may cause the driveshaft to explode. He also then pointed out where in the car the driveshaft would explode and pierce thru the car from the prototypes he had seen.

He mentioned this because we were testing a dampner on the driveshaft to see if it changed the harmonics and was concerned because we didnt rebalance and retest the driveshaft before driving the dampner may have moved the critical rpm to a much lower speed

So in agreement with the others I bet it is a driveline speed issue.

ok put the E-peens away. if you want to go 100+ MPH in a 3 ton truck by all means do it, but do it at the track and stay the hell away from me and my family on the public roadway. this thread is done
