: Governed at 110 mph!?

I was driving to the shore Thanksgiving day. My friend was in an 07' Denali & I was in my Esky. With no traffic we started to push it a little and both found these things are governed at 110mph. I know it sounds silly but does anyone know if there is any way around this? It seems crazy to throw 403hp in a truck and then limit it to 110.

You can use a programmer like Diablo to change the factory set limits. Probably not safe to go much faster than that. What are your tires rated at??(130mph??) Im sure the factory braking system isnt safe beyond that and possibly not even at that speed.

it's limited because the aerodynamic properties of an Escalade remesemble that of a Brick, besides what Mrholland mentioned. Beyond 110mph the truck becomes unstable and none of the various suspension or braking components are designed to stop the vehicle going that fast.

I'm surprised you didn't run out of gas before you got her moving that fast! :devil:

I believe it's really 106, but speedo error could easily say 110, I don't have that annoying feature anymore, it's just gone, of course driving over the speed limit is not legal anyway. :)

107 is the limit, mainly due to the rear driveshaft. Above that speed the driveshaft will start to induce too much load (jump-roping) on the transfer case and rear diff pinion bearing if it is at the upper limit of the imbalance specification.

I just have to ask! Why would you need to go 110mph???

I wonder why the speedo goes up to 160. I know just cause it is there doesn't mean it will go that fast, but that seems a massive way off. It should go up to 120 then...

Friend of mine has a Model A and if memory serves me correctly, the speedo reads 80 MPH. Auto manufacturers have been playing that game for years!! LOL!!:yup:

I'm honestly afraid to drive mine over 90mph...its really not meant to be driven fast. It feels like its going to fly off the road with the slightest dip and the thought of having to manouver even a mild curve or have to stop at those speeds is scary. That's why I love to drive it...I never get any speeding tickets in it :)

it just makes the car feel special, or it's cheaper to make 1 cluster face. Who knows.

Stock it pretty much feels this way, but with good sway bars and good tire balancing, not how they come from the factory, but once you get the tires balanced good, these trucks will cruse for hours at 100 miles an hour, that is only slightly higher the the speed limit in Montana of 85 mph, of course you need to be pulling a gas truck behind you. :)

Thanks for all the info guys. I was expecting some of the comments about the speed limit. I still get the speed jones once in a blue moon. I've sold the GSXR and my last camaro got sold when the twins were born. I don't intend to do that kind of speed alot, but I do like to play now and then. I guess the mods will start this spring. I'll be busy working on the softail this winter.

Mine handled great at 118...felt like 80...just make sure there is nobody in your car you care about and plenty of road to stop. I did it once but its nice to have when you are challenged by another Esky or Denali.

Do the new body denalis still have the 6.0? Or the same 6.2 as the escalade? If it does have the smaller engine how did they compare

The new Denali's have the same engine as the Escalade, 6.2L.

Main reason it's limited is because of the tires.

Now if you put higher speed rated tires on, and disabled the governor, you would probably top out around 140 MPH. At least that's what the Michigan State Police got a Tahoe up to with I'm assuming the 5.3L V8.

I bet emergency braking and maneuvers at that speed would create some butthole puckering moments.
