How fast can you drive a Jeep?

Post by Torque » Fri Sep 27, 2019 5:59 pm

Finished my GPW this spring (everything rebuilt) and kept it under 45 mph for the first 1000 miles. At a 1000 went to 50 mph and at 1400 miles started driving 55. How much faster can I go without scattering engine parts down the road?

I’d say that’s about it, maybe up to 60 although the faster you go the faster your engine wears out. One thing you have going for you is everything in the steering is rebuilt and every thing is good and ready to go.

I used to drive them at 60 MPH over the I74 Bridge to work on RIA.
I would not do that now for any amount of money; it is not the speed; it is the fact that I now, at an older age, realize that jeeps of the period are death traps if something happens. Like a teenager texting pulls out in front of you. Which they will. I now keep them at 40 max and avoid traffic. And drive more Dodges, less jeeps.

I live in a city in S. California. 40 Max or I'm asking for trouble or death. I like to cruise around 35 most of the time

If you want a race car you overhauled the wrong vehicle. Dang, did I say that out loud?

How fast can you drive a 75 year old truck? As fast as you want. That's what makes America GREAT! Until you can't. Maybe with jeep parts or worse --- human body parts scattered down the road.

Maybe sitting on the gas tank without a seat belt has something to do with it? Along with all the idiots out there who weren't there in 1945 that can't stop finger-fornicating their phone while driving, or those other idiots that think they're at Talladega and just have to get one car ahead.....

Good luck out there!

Not defending teenagers, but in my neck of the woods there's a ton more so-called adults (who ought to know better) playing with their so-called "smart phones" while piloting 3000+ pounds down the road like the nut-jobs they are.

Where are the cops when you need one? (Before the accident, not after) Oh, yeah, they're doing the same things. Dang, did I say that out loud? :shock:

I'm guessing traffic and cell-phone coverage in Iowa must be pretty light. :lol:

Yeah, 45 or so for me most of the time. My CJ/MB clone will do 50, but once you realize that it takes a ridiculously long time to stop (even with 11" drums) coupled with no airbag, no crumple zones, and the steering wheel in my lap, I think 45 is quite fast enough.

If you want to give your engine a reasonably long life, 45 MPH is a good pace with bursts to 50-53 MPH. I have 10's of thousands of happy 1940's - 1960's Jeep miles under my belt that were used for both work and pleasure . A feather touch and a moderate speed has worked well for me.

At least with mine - I can't imagine going much over 40 mph or so. My usual joke is that if you want to go faster, it needs to be dropped from a plane.

Even at 35 mph, it seems like you're going 90! Very exciting. Nothing like as safe as a modern vehicle. One of my concerns is that the jeep just isn't like a modern car in terms of speed capability, stopping distance, stability, etc. And drivers in my area typically go 45-55mph in 35mph zones. Not a comfortable feeling to be the slow one amidst a bunch of impatient drivers.

One thing you're not likely to see -- a jeep driver texting on his/her cell-phone. The jeep definitely has to be driven! All the time! Or you're in a ditch before you know it!

40 MPH, absolute max for me, but i always drive with the screen down , so 40 seems like 70 MPH, especially when you get hit by insects etc. OUCH.

I prefer 35 mph and will go 40 at times. All of the advice above is "Mona Lisa Vitto" accurate. Enjoy your jeep at speeds it was designed to handle.

I have driven mine pretty fast.
We had a day at Brize Norton (UK airbase) stuffing Jeeps into mock ups of transport planes. The base is about 30m miles from where I live. We were supposed to take our passports and I realised a couple of miles from the base that I had forgotten mine so I had to turn around and go back and fetch it.
I drove the backside off my Jeep in order to get back to the base before they closed the gates. The wheels started to wobble a bit so I drove a bit faster. That cured the wobble. The only car that came past me was a Porsch GT3, which frightened the hell out of me because he dropped a couple gears as he came past. A few days later I was recounting the drive to a friend of mine and he said his mother was following me and she could not keep up. I had no speedo at the time as it was in for repair so I do not know how fast I was going but I was not hanging about.
I made it back to the base and was the last one in, and to cap it all I did not need my passport after all as they had done back ground checks on us all and knew everyone that went.
I do not think I will be driving that fast again

Im another 35 to maybe 40 tops guy. The vehicle just feels happy there. I do have an M38 with a a Saturn Overdrive installed. Have had that one up to 60 but oh my gosh! :shock:
Talk about feeling like Scotty on Star Trek. Eyyy Captain! I donna know how much more she can take. She's coming apart at the seams! It doesn't shimmy of any thing bad mannered like that, just feels like its being overstressed. That and at that speed you start to measure stopping distance in counties, not feet....

"I'm guessing traffic and cell-phone coverage in Iowa must be pretty light. :lol:"
I don't know what part of Iowa Torque is from, but where I am, also in Iowa, cell phone coverage is 100% (it ain't mountains but it ain't flat either), and texting whilst driving (yes, from teens to age 60; idiots know no age limit) is rampant. And yes, they drive very carelessly here. Off in the country, you will be killed from the rear. In the city you will be killed from the side. Same result.
