Speed limiter??

[KARNUT]

Really, they have been plenty of sport trucks over the years from the big auto makers. TRD, SS , Lightning to name a few. The truck is one of the easiest platforms to make ( mod) into anything your heart desires. You sir are way out of line.

Lol, those "idiot" engineers trying to help people by making it so the truck won't disintegrate going 140. What the hell do they know.

These are trucks not sports cars. again. These are trucks, NOT sports cars. Here is some info to help some of you out since you obviously don't know what you are driving.

 

http://en.wikipedia.org/wiki/Truck

A truck (United States, Canada, Australia, New Zealand) or lorry (United Kingdom and Ireland) is a motor vehicle designed to transport cargo. Trucks vary greatly in size, power, and configuration, with the smallest being mechanically similar to an automobile. Commercial trucks can be very large and powerful, and may be configured to mount specialized equipment, such as in the case of fire trucks and concrete mixers and suction excavators.

Modern trucks are largely powered by diesel engines exclusively, although small to medium size trucks with gasoline engines exist in the US. In the European Union, vehicles with a gross combination mass of up to 3,500 kilograms (7,716 lb) are known as light commercial vehicles, and those over as large goods vehicles.

 

 

For you rednecks:

truck

A vehicle of a redneck, which he drives to a date with his girlfriend instead of carring grass for cows.

Wow. Talk about being out of touch with reality...

 

Ok, GMC Syclone. Pretty hard to confuse it with a "sports car", yet is has a 500# load limit and ZERO # tow rating. My wife's Bonneville has a higher load and tow rating.

 

Oh, and zero->60 in <4.5 seconds. Clearly somebody should educate GM on what a "truck" is since they are just confusing us consumers now.

6.2 NHT pkg 98mph......and it pisses me off every time I get in the truck. Not that I drive faster than that very often. I don't like the idiots at GM telling me how fast I can go.

Are you sure you're hitting 98? Mine just seems to barely peg 95 every single time. Definitely aggrevating! I can't even hammer past someone on the interstate without hitting it. LOL

Sometimes it feels like it cuts off before 98mph

Stock my 6.2 with the 3.42's was at 112mph, since I tuned it I took the limiter out of the tune.

Interesting. 3.73's here.

14 SCSB 4x4 5.3, cuts off at 112 on the dot, verified it with gps to make sure my speedo wasn't off.

I have an SLT crew cab with 6.2L engine, 3.73 diff & 20" eagle tires (tow package) that tops out at 160 km/h.

 

My buddy's Denali with 6.2L engine, 3.42 diff & 20" Wrangler tires (Z71 package) tops out at 180 km/h.

 

My truck gets there a lot faster but I don't understand why his speed limiter is higher, especially with the tire difference. His truck was built a month or two after mine, and I picked mine up in March this year.

obviously you must have raced your buddy just curious how far ahead of him you are when you hit 160 and it shuts down

Here is my 2014 Sierra 1500 CrewCab SLT 5.3 with 3.42 gears on stock tune with no muffler. I had the pedal on the floor the whole time. I'm pretty sure GM set the speed limit because they know the hollow aluminum driveshaft can't go any faster.

I don't understand why we keep pointing at an aluminum driveshaft as being the weak link. I have read this many times on this board. Is there something about these that is failing? I put 640hp to the ground in a 4400lb 96 impala that had an aluminum drive shaft and it would pull the front left wheel on a 200shot of nitrous out of the hole. I can probably dig up a video if I have to. This car withstood 6 years of solid abuse with ZERO driveshaft issues.

Bottom line... If our driveshaft is failing, it's not because it's aluminum. I'll buy poor material grade choice, too thin of wall (my driveshaft wall was .125), poor welds/craftsmanship etc.

And I certainly don't see how rotation speed is going to make it weaker... Applying 640hp from a dead stop is going to produce much more abuse.

 

As soon as I get some info on what ours is made of exactly, I'll try to do some calcs on it.

What is the best option to raise the limiter above 98MPH? I see a bunch of tuners out there, any good or bad experiences with them?
