Chuck,
The WWII JEEP drivers were a bit more motivated back in WWII and the Jeep was designed to take it.

Wow Mr. Dover. That's astronomical. Might even be "ludicrous speed". :shock: :lol: https://www.youtube.com/watch?v=ygE01sOhzz0

And all this time I thought they were designed for combat -- with maybe a 30-90 day life expectancy off-road or maybe semi-improved roads. Not counting getting shot at while doing it.

None of which looks anything like what's outside my front door in 2019.... :roll: Your neighborhood might be different. :lol:

And for the naysayers. This is my M-38A1 that I have maintained to factory spec since it was new. It will wind the needle past 60 all the way to zero with no effort. I do not do this very often. It does make believers tho.

Do not judge my JEEP driving habits by this post, and do not attempt it if your JEEP is in 100% factory spec Bumper to Bumper.No, it is not running, this photo is meant to represent the layout of the Instrument Panel and the Speedometer for those who are unfamiliar with the M-38A1. The M-38A1 Speedometer is calibrated to the same turning speed as the WWII Speedometers in the MB/GPW, WC, and CCKW, etc. They are alos an ideal temporaru Speedometer for MB/GPW which many of you have already witnessed.

I don’t know how long you can maintain that speed with no fuel, no oil pressure, and no voltage at all! :o BW

Uh, you think he will actually take that jeep down the road while making a video and spinning the needle all the way around to zero?

Don't hold your breath....the excuses will be posted soon enough....but he can't use the standard response he falls back on when asked for pics or for a manual do you..."Well, the snow is piled against the door so I will have to get that for you in the Spring". Almost as bad as "The wife has the camera and is away for the weekend".

One should be able to run a smooth 64mph with good control and solid engine. Now, I don't normally run this fast. But after I have done a frame up resto, and all the bugs are worked out, the engine is properly broken in, then as a.final test of all systems, I take her for a short run up to the factory rated top speed. Zero issues. After that, my normal max speed is around 50mph. Most roads I choose are 45mph.

Perhaps a guide here to help with your decision:
1. Age of your Jeep?
2. Quality (objectively) of work done on/to/replaced critical components?
3. Your age and driving skills, again objectively. (Eyes in back of your head, ability to swivel it 360 etc.)?
4. Location of driving, traffic and weather conditions?
5. Married, single, community property state, kids still in school/going to college?
6. Wife on your butt, kids on your butt, boss on your butt?
7. Amount of your life insurance policy and wether suicide is excluded? (see1-4 above)
8. Plausible reasons (objectively) of going more than 45 MPH with zero occupant safety equipment?
9. Just to see if it will? (Really?)
10. OK, I'll hold your beer.

Here to help ya, not to hurt ya. :D

Hello all
I drive on one of the busiest road systems in the world. At speeds I would deny if I was in front of the judge. So to get into my gpw with the screen down is a pleasure. My matching number has never been rebuilt so I tend to nurse it along at about 35-40 mph. Fast enough when some c*** decides to overtake then ,brake. So that some a****** on the back seat can take a picture :roll: We should all realise how driving old vehicles has to be done properly. Otherwise we would have a lot of spare parts coming onto the market. :wink:
regards Nick
