J10 w/ a 360, Do they fly??

[back2spool]

Look, I am not a speedfreak. Always preferred big and boxy over sleek and quick. I just got my first FSJ a couple months ago. It's a Waggy w/ a tired 360, but to me the thing moves pretty **** good.

So I was wondering about you guys with the J trucks. Do they just fly (being lighter and all) or what?

I really like driving my Waggy, love it as a matter of fact. How does the "feel" of a Wagoneer compare to that of a J-truck? Please describe...

[Ristow]

j truck weigh about the same as a wag or cherokee.they do allright,wouldn't say they fly....


drive the same,lil' rougher.

[janie]

Rumor has it, that when they get low on fluid they move along at a pretty good clip.:D

Back on topic. A 360 in a J series contains the same type of aerodynamics of Godzilla on iceskates.

I don't think you'll find much variance, but the Wag would prolly do better. No open bed to catch the wind. I'm sure my brothers and sisters here who own both will chime in.

[Kali]

i thought the wagos had close to a 1,000lbs on the pickups?

my j-10 with the 258 and 4.10s gets around pretty good. would love a v-8 in it, but i probably wouldnt swap unless i get my hands on a 401.

as far as ride quality.. the pickups are rougher and louder. i have an 88 wag and the ride isnt quite as good as newer SUVs, but they are very quiet inside. You'd never know you were riding inside of a brick shaped vehicle. plus they are all windows... love the visibility in the wagos!

[back2spool]

Ouch!

I was just curious. I guess it would make sense that they weight close to the same now that I think about it.

Just curious is all.

[frank_c]

mine will do 80. i'd much rather drive my car if i need to go that fast though.

[shackwrrr]

well the balls to the wall, all out top speed of my j20 is about 95 thats where it reaches terminal velocity the wind resistance outwheights the engine power. oh yea It whas pushing like 4500 rpm

[Ristow]

my '83 cherokee & '91 GW are about 4400 lbs,my '74 longbed J10 Q/T was around 4300. weighed on rthe new truck scale at the shop.


curiously,out '98 Grand cherokee I6 was 4200 lbs.

I don't think you'll find much variance, but the Wag would prolly do better. No open bed to catch the wind. I'm sure my brothers and sisters here who own both will chime in.

Dunno if anyone here watches mythbusters on the Discovery Channel, but they did an episode that proved the open bed of a pickup actually doesn't create much wind resistance. Something about a "bubble of air which spins around inside an empty bed when the tailgate is closed, causing the airflow to go over the bed completely, as if it were covered. A fsj isn't all that aerodynamic to begin with though, heh.

However, I don't have a wagoneer or fullsize cherokee, so I can't actually compare them, though I doubt I'd have a problem keeping up. As for how j-trucks with 360's do, acceleration isn't impressive, which you'd expect from the v8, but they do great once you get em going. It'll spin the rear tires if you hit the skinny pedal too hard, even on a dry day. :D

Unless you're stuck with one of these silly quadratracs. :(

[jaber]

Mine is a QT and the only way I could break the tires loose was in reverse with the wheels cranked....

No difference between the Qt Chero and the Qt J. Now the GW with the cam and injection, you can feel it in the seat.

[Jeep_Guy]

I'm pretty sure mines got a np208 transfer case, has the little flag 4wd shifter on the floor too. Forgot all about Quadratrac trucks, oops.

[Kaiser]

Godzilla on iceskates...
:funny:


Hell, even with over 500 bhp I would'nt say my Gladiator even gets lift! These are HEAVY rigs to begin with, and would take alot of power to fly.
Fun trying though.
My VW TDi is much faster on the road...and I can get over 60 mpg consistantly.

[bigun]

Crom will run out some where around 80 according to the stop watch. That's running 37s on 3.70 gears sucking a ton of propane!!

[back2spool]

The windows are one of my favorite things, along with the thin posts. My brother-in-law (engineer) says the roof would crumple pretty easily with those thin posts,but I don't plan on rolling over anytime soon.

Also, the ride is soooo smooth, even with the sagging rear. It blows away driving my Wrangler in terms of comfort, but I can't take the roof off like I can on my YJ.

Thanks for all the input/thoughts. I am intrigued by these things, and people's thoughts about them. My wife came i nand asked if I was on e-mail, I said, "No, Jeepmail." She said, "Oh brother..." I said, "Hey, don't knock my jeep friends!"

And so it goes...

[talntar]

beleive it or not the roof is pretty strong.just ask my wife.she rolled her 79 on the way to work a few years back.

[KaiserMan]

My J2000 flys about as well as a 5,000lb brick can be expected to.

[grand_wag_85]

I drove a 454 powered J Truck once:drivin:






:D

Ride wise the J10 will be a bit stiffer but for me, 5'6", the J10 is a better 'fit' than the Chero or the GW was

They also proved that putting your tailgate down does not improve MPGs, it actually hurts MPGs.
The nets actually do increase MPGs slightly, tailgate up is normal, and tailgate down lowers MPGs.

[motox-010]

Ditto on the thin posts. So much easier to see when you are turning. I hate to drive our Taurus because the A pillar is so d@mn wide!

[fulsizjeep]

I saw a 78 Cherokee WT fly once... Trust me, you would not want to be behind the wheel for that event.

[Carl Rasmussen]

Maybe fly off the road around corners :D

[Heavy_Metal_Thunder_81]

I hate QTs!!! I wanna do burnouts in the Wag...:(

[fulsizjeep]

Even you can do burnouts with a $600 Milemarker conversion in your QT. Still wanna do burnouts? ;)

The nets actually do increase MPGs slightly, tailgate up is normal, and tailgate down lowers MPGs. yes, tailgate up does actually help as it creates a circular air flow that softens the 'drop' of the air behind the cab. but a net would hurt you. it would slow down the air going through it and cause more drag while disturbing that circular air flow you'd get with a tailgate.

net - bad
no tailgate (or down) - ok
tailgate (up) - good

Al

[Kali]

on that episode of mythbusters they proved that the nets were most fuel efficient.

[AlsChopShop]

i watched that episode too and i'm pretty sure the nets were the worst.... after all you only saw them in the 80's, and they are no more.

Nobody ever plans on rolling over, but it does happen. My wife and I walked away - the posts are stronger than they look..

The problem with the test on Mythbusters is every vehicle make is aerodynamically different because there are different cab and bed sizes. You need to do your own testing because i've found out that my old '96 Dodge Ram extended cab short bed 1500 4x4 got better mileage and had more power with the gate down. Also i think they used 2 different trucks for the tests (both Fords) if my memory serves me right and of course it would have to be done at exactly the same time to have exactly the same conditions: temp, humitity, altitude, barometric pressure, and driver duplicating the driving. IMHO.

[Kali]

yeah the testing was not totally accurate 100%. either way i drove around with my gate up and will continue to do so, regardless of what they proved. dont want some idiot taking out my perfectly good (and increasingly more rare) jeep tailgate ;)

[TexTJ209]

Yes, but then you still have a Quadratrac. Problem not solved. ;)

[tyrodtom]

I remember the Mythbusters episode, the wind-tunnel model they used was a 4-dr with the very short bed, the results could have been completely different with a long bed. I remember back in 89 when Chevy first come out with the 4.3 V6 in a S-10, they took one to the Bonneville salt flats and broke some class records. They ran tailgate up and down, would have to look it up to get exact figures, but they quickly decided to run their record runs tailgate down. Mythbusters make a lot of blanket statements, what holds true with one vehicle may not be true with another. For example they did a A/c windows up, or no A/C windows down, which uses more gas. They did it with a SUV at 45mph, and found it uses less gas no a/c windows down. I think it might come out different in a more streamlined vehicle at a higher speed. I'm a amateur pilot, aerodynamics is a sticky wicket.

Waggy401 that is soooome pic.

Thanks, I will share it with my brother-in-expertoneverything.

Glad you are here to talk about it man.

[shimniok]

not like I'm actually adding anything but why not spout off...

the A-pillars are what usually crap out on the rollover pics I have seen.

I think with manual trans and a few hundred less lbs the J's probably are a little faster than Wags. It would be hard to make them super fast, but I have seen a Wag accelerate from 70 to 100mph in about 5 or 10 sec... was pretty impressive to see, but that is an extremely unusual motor (401 that was built VERY right at least for hwy power) and that one is running 33's and 3.31:1's.

Mine with a stock 100k motor does ok... lots more low end than the rebuilt 360... seem to be able to run 85 on relatively flat ground without too much trouble... probably has a little reserve but I don't exactly feel stable and safe above 75...

I can get the tire chirping, cuz I have a locker :) Can't spin tires in the Subaru... darned AWD :)

1st FSJ - 74 Wag - 258 -a real dog...and I tried everything I could to get it to go faster...at 16 years old a 4 door wagon is not cool, so I wanted to get past my friends as soon as possible.

At 17 bought a 79 J10 SB with the 360...and it did pretty darn well if I do say so myself...not much done to the motor, and I ran with a Chevy 454 SS truck up to around 95-100...then he took off and I caught up in town. But I got a little back out in the country that evening by pulling his pretty truck out of the mud...:D

Now driving my 70 glad with the 455...and I have no idea how fast it'll go and have no intention of finding out...amazing what a couple of decades will do to the "need for speed"...:drivin:

[elij10travis]

well the 360 v8 are nice enginge but all depends on your tranny the three speed is alright along with the 4 speed but ya they cna get cranking pretty good let me tell ya what i own an 1980 fsj j10 with 360 4 speed and it doesnt do half bad driving down the road.

[motox-010]

I caught some air in my Jeep last night. That was cool.

[78J10honcho]

it's only cool if you're expecting it, sometimes fun in the snow=:omfg:

[J4GRAND]

Old post which I don't remember seeing.

As for how j-trucks with 360's do, acceleration isn't impressive, which you'd expect from the v8
Janie- I resent that remark. You saw how my J4000 accelerates and that wasn't even fully hammered. If I weren't in downtown S'ville, I would have really shown you acceleration.:D :eek: :D
