100 mph in a TJ; have you done it?

And with a check engine light
lol, My jeep thinks its had a broken torque converter for the past 55,000 miles and I no longer have any emissions systems on my jeep lol.
Funny, my Jeep doesn't know I have a broken TC, but my temp gauge and the pedal feedback in lockup reminds me. :/
You’re absolutely right, I never really thought about the speed rating on the tire. I’m sure there’s a safety factor built into the rating though- probably at least 1.3 percent—so I bet I could’ve gone 130 before it became a problem.
The thing is, speed ratings on tires are a moving target. The speed rating is calculated at a certain pressure, temperature and load. Change any one of those and the speed rating can go up or down. Just like the other ratings, each one affects the other.
I do have to laugh , a tire speed rating discussion on a Jeep TJ Forum . I can't wait for the lateral acceleration portion of the test ! ....
Don't think I've ever hit 100, but 90ish on open interstate, elevation, and a slight downhill. My LJ actually used to feel pretty solid at speed but my steering box has loosened up a bit so it's getting sketchier.
Drag force and engine power are both linear to air density, but I mention elevation above because wind noise is proportional to the power dissipated by drag force so it's noticeably less noisy and I'm more prone to speeding at elevation because quieter unconsciously feels slower.

I went 105 in my 89 comanche once. Google maps GPS verified - notice I said I only did it once? But it was very comfortable at 85. It was stock height with slightly smaller than stock tires.
I've spend considerable time on track with a motorcycle, gets the speed thing out of my system. No desire to push my TJ past 70, even when new and in stock form. With the aerodynamics of a cube, it wouldn't take much of an unexpected side gust to create a really bad day.
Yeah, I started it recently so I don’t have a ton of content, but there are a few pics. https://wranglertjforum.com/threads/swiss-cheese-a-tj-6-story.85665/
In fairness, this thread would have a lot more responses if it weren't for the fact that most people who have gone 100 mph in a TJ are ... you know, dead.
I rode liter bikes for 15 fifteen years and never stopped liking speed.
Safety at speed largely comes down to the quality of your rig, and desert gusts aren’t a problem when you have dialed in hydro assist steering, a swayloc, and well tuned outboarded shocks. Adding the turbo put the rig in balance rather than create an imbalance.
Blaine’s suspension and steering work has made the rig ride better than it probably should, and I assume a properly setup stretched rig rides even better.
Yeah, I saw that. I also saw that I've posted there a few times. Don't get old, Dude...
And by the way, congrats on the engagement!

Hell no. Going 100 in a TJ is one thing, going 100 and turning left is a whole different ball game
And turning right would be even crazier!

I'm not too sure about that. When I took my 99 over 90 m.p.h. it was at 6100 ft. elevation , The Jeep sounded like a B - 17 , balls to the wall , in a 75 degree dive.
It was LOUD .
