I would guess that the chip in the motor will only allow you to go a certain speed. so i would guess it tops out at about 110. cars have chips these days. you can remove them, but i wouldnt. they are there for a reason

 

If you try, keep a gas truck hooked up behind you... Probably talking 3mpg at top speed! I rarely go above 85....

Now in my Vette I've hit 164....

 

I believe the top speed is (electronically) based on what model you have, and that is strictly based on the speed limitation of the factory tires.

I've had mine up to 100mph no problem. I think all Rubi's top out at 99mph.

One of the "benefits" of the 3.6 is that is actually more of a high end car engine than a truck/Jeep engine, so higher RPM's are not an issue.

Our limits are more of the issues with a boxy Wrangler on high profile tires with weak brakes and such.

This is the same engine in the Charger and Challenger.

I don't own one yet (on order), but when I drove the 3.6 the thing I noticed immediately was that it liked the higher rpms better, that's where the added hp was evident. Down low, I'm not sure I noticed much difference in torque with it and my 3.8.

Now, if you want to increase your top end speed, just add some stickers, they are good for at least 5-10mph.

 

I never have been over 80 MPH on my JKU. I cruise more like 65-70 on the highway.
I have learned to slow down and enjoy the drive, LOL!

 

X2!

I prefer to drive fast from my previous vehicles but now I have come to love the right hand lane and just cruising along!

 

99 miles per hour (speed limited) which is the limit for stock tires. I've been there with the pentastar.

 

I had mine on a long straight stretch slight down hill and I was pulling right at 160...... then I realized I had the evic in the metric mode. These are bricks probably a good think they are limited to a ton. I generally cruise on the highway at 75-85mph and mine does great at those speeds.

 

Someone here had theirs up to 112 (or whatever the limit was).

They did it on a runway strip.

 

Why? The thing I like most about my Wrangler is the speedo only goes to 100, lol!
Absolutely no pretense, it is a military themed vehicle.

 

100 mph on a 2015 Rubicon. For sure. I learned this on the test drive before I ordered it... it got to 100 with about 3/4 pedal and pushing it further did nothing. Obviously electronically controlled.

The salesman about shit his pants.... not quite, though.... He didn't actually shit his pants until I pulled off the road, threw it in 4L, locked the diffs, and climbed over a dumptruck load of freshly dumped fill dirt.....

It was all good in the end, however....... he went home with a fat commission check when I ordered a loaded Hard Rock..

I would never buy a vehicle the salesman or anyone else took a shit in. And as to the discussion at hand its limited to 99 I've had my two door to the limit. It could certainly go faster if it was allowed to.

 

I ran my jkur up to the limiter of 99mph.
after I installed my superchips trail dash set the limit high as it would go (145mph).I have only had it up to 105. but I wouldn`t recommend it hood was wanting to raise up and wind was pushing my rubi around..

 

I drove 75 down from Indy to Nashville a month or so ago and with the 20-30MPH crosswinds I felt like I was going to flip over. Definitely not as smooth of a driver as my old Charger was. The fastest I've gone is 75. The slowest I've gone is VERY slow on a nice day with the top off.

 

I see people saying they went up to 160 mph. How is that even possible if the speedometer only goes to 100 mph?

 

Speedo is limited to 100, but momentum and other conditions can allow the vehicle to actually travel at a higher speed.

 

Just because the speedo stops at 100 doesn't mean that's as fast as the vehicle will go. That depends on what the limiter is set at. I had an AMG Benz with a speedo of 220 and a 181 limiter. You could measure it with the speedo on the nav of you peg it. But doubt you will in a JK

 

I've topped out the speedometer on my JK Sport before, but to be honest at those speeds, it doesn't feel all that safe in a top-heavy Jeep. I usually cruise on the highway anywhere from 75-85 and with the 3.6 engine, the RPMs aren't that bad at those speeds. Actually pretty good gas mileage too... for a Jeep.

 

I have a 2013 4 door Sahara that is basically stock. So when I hit 100 mph, it was actually really stable. I was in Sunrider mode with the rear window flopped (but the rest of the windows rolled up). My sister in law commented on how it didn't really feel like we were doing 100 mph. She said she knew were we going fast, but not 100 mph fast. The longer wheelbase and slightly lower profile tires probably played a part in high speed stability. I also wonder if the stock Sahara side steps act like some type of ground effect kit as well?

I've only done it once, as I usually don't go past 73 mph (fuel cost). But the vehicle is rock solid at speed.

 

No idea, I'm good with 70-75mph, an iced tea and good music. These shoe boxes are not made for speed, so I'm not good with risking the lives of my family, friends and other families on the roadways!

If in that much of a hurry, I fly !

 

I had mine up to 75 on the way home from getting it lifted, thats how i found out my tires needed to be rebalanced hahahahhaha

 

I mean I've gotten my tj to 105 before, but my friend got his jk to 157 mph not kmh. I called bs and he showed me pic.

 

I believe it. I did 142 in my 13' JKU in Mexico on a 1 1/2 mile straight 2 lane road, was pretty scary but I've been 200 before as a passenger in other cars. And how accurate was the speed? I don't know i'm just going off of the uconnect gps.

 

In a vehicle that's theoretically susceptible to death wobble.

I wonder if this is why the company wants to take away the front solid axle.

 

It’s a troll

 

Lol.troll waking up an ancient thread. Bla.

 

Im not trolling lmao, I was genuinely curious if other people had topped one out before. How about we make a new thread asking? I have a picture of the uconnect gps speed I'll need to find to post or tonight I can go to Mexico and do it. Idk if the car still has it, I did this in 2016 when the car only had like 20,000 miles on it, now its 100,000. I cleared the gps because of warranty I didn't want them seeing it and possibly heehawing on the warranty. The fastest I've gone in it since is 105.
