Builds 1988 BJ74 “Number 1” (20 Viewers)

[FJBen]

Took a small work trip, 1.5 hours down the interstate then backroads on the way home.

On the trip she rolled 560,000kms

As for the temps on the trips:

Interstate - 70mph, slight tailwind, 78F, 2400rpm
Water temp 187F
EGT - 800ish

Backroads - 65mph, headwind, 80F, 2300rpm
Water temp 185
EGT - 830F

So far it seems that it just sits at 185-188 at 65-70mph all the way into the 90s in temperature.



Big ol storm rolling in on the way home

Those are pretty good numbers., and I'm not sure it's worth the effort for you to squeeze an intercooler in there.

Nice photos. I miss those western storms; they remind me of big squalls blowing up on the ocean and you never know which direction they are going.

Yeah that’s where I’m not quite smart enough to know a ton about IAT temps and volumetric efficiency blah blah.

I know an intercooler would definitely help performance and having cooler IATs really doesn’t have negatives, all though most of the time my boost is 15psi or less.


I do think I’m going to put the cylinder head temp sensor back on as well. The good thing about that is that it will read when there is no coolant.



Yeah we get some big ol storms that converge out here and just thunder and hammer like nobody’s business. I love a hit thunderstorm at night and we have had plenty this year.

Interesting difference in growing seasons. A good percentage of our corn crop is either already in the bins or soon will be.

Knee high by the 4th of July is the statement around here about corn. Harvest is around September to November.

Daaaaaum! That 13B Cool

 

[FJBen]

Just got back from another trip in the cruiser. 3 hour drive one way…95 degree heat, no ac.

I pretty much chugged along at 65-70 the whole way. Ended up having to drive a few more trips of a couple hours during the week as well. Total trip was about 800 miles worth of driving and it looks like I averaged 21.7mpg


stalked by this sprinter for quite awhile….also a plus to having a narrow 70 series, when they move traffic cones over, most cars are straddling the white line and hitting rumbling stips…a 70 fits just fine.

Oh Colorado and your Jeeps…. A quick stop at HTeaO…thankfully no ducks were placed on my cruiser.

Beef Country.

Some nice front range cruising.

No words…

65mph, 97F, headwind and rolling hills. Most I saw was 196F for coolant.

A little bit of 13bt power! not a full flog

Mad respect for using that rig as you do man! You know I already felt that way, but you keep doubling down with more crazy trips!

Yeah I feel like I don’t use it enough! One trip this week was a rush trip from Fort Collins to Denver in the middle of the day to pickup supplies that were only in Denver! Mid 90s, interstate traffic, BJ74 for the win!

I did avoid I25 on the way back and crossed over to 287.

Getting it all sorted to go on some longer trips. Some new seats would help a ton!

Hello,

As my mechanic likes to say, put on miles on your Land Cruiser's odometer and enjoy.

Yeah she hasn’t been on many longer trips so that helps work the engine a bit more. It was plenty warm out for it.

The only casualty of the trip was my turn signals pretty much quit. Every so often the will work, but this randomly happened.

I feel like there is a loose wire in the steering column as sometimes it works when turning and everything is fine, the next it’s slight buzzing and no flashers or turn signals.

I read @jblueridge had a similar issue and it turned out to be a loose wire in there.

I just got back from the Solid Axle Summit in Ouray Colorado. I pulled this ~3,400 pound trailer through Utah and Colorado mountain passes for 640 round trip miles. I averaged 17.4 miles per gallon. Combined GVW for truck and trailer is ~9,000 pounds.

I climbed Davis Pass in low range 2nd and 3rd gear.

Awesome! I’m sure you could feel that trailer.
What was your highway speeds in it?

 

[cruiserdan]

On flat ground and moderate inclines I could maintain posted speed limits. On steeper inclines I grabbed lower gears as my speed declined. In all but the steepest climbs I was able to crest in 3rd gear at around 45 miles per hour.

Sounds a lot like driving an unladen BJ70

 

[FJBen]

Oh the turn signals…

Opened up the steering column because it sure felt like a short. They would sometimes work, sometimes tilting column made them work.

Yep, that wire was disconnected. Soldered it on but no worky. I looked again and this board looks cracked.

So horn works, lights work, wipers work, no signals or hazards. The relay was working before fine, I suppose I need to pull and test, but I’m guessing the unit is just shot.

84310-60550 I believe is the part number…at $200 plus shipping

 

[Felde]

Can you get the board out? What's on it?
Simple circuit boards like this can be recreated or even be repaired by removing the insulation laque, soldering in some bridges over the crack and insulated again.
