This Ranger has a mid mounted engine with three transmissions and two transfer cases!!! An automatic of some sort, then two NP435s and two NP205s. It's very cool and flexy as hell.

Seems like a lot of extra cases to get bashed to me.....but YEAH a cool idea.;)

So he'd be about 430:1 without even taking the axle gearing into account. Lets guess at 4.10's and that's almost 1800:1 :eek::eek::eek:

WHY?

That seems like such a waste. Too much trouble for no real world benefit. I think that is kinda dumb...

Then add in the 2:1 for torque converter....

3600:1


Could you even SEE it move? :D

Yeah and a 2000 horsepower Top Fuel dragster has no real world benefit either. Doesn't stop it from being cool.

Gee why does that look like a TTB front axle welded together to make a solid axle :rolleyes:

Because it is, (Dana 44 version) strange but it seems to work. Not sure why he went that route especially after all the other work with the drivetrain. :confused:

Using 3600:1 or even 1800:1 could someone figure out how fast he would be moving at idle (like 600 RPMs) with whatever size tires he has. I'm guessing it'll be ft/hr:D

I could do it but I crunch numbers at work for fun, so I'm about all funned out

1800:1 on (guessing big) 39.5" TSL - 1.5 sec/inch, 7.2 min/ft, or 12 Hours to go one mile!

He could time out on a coarse before the back tires cleared the start gate!!! :rasta:

@3600-1, 600rpm (idle)

it would take 6 min to make 1 revolution of the tire

2 full np-205 = :rainbow: That thing has to way a ton. Why not stack a shitload of 203 or toy reduction boxes, for the length he's used I'm sure he could run an auto tranny and about 5-6 toy reduction boxes throw in some 4.7:1 gears :eek:

2.48 x 4.7 x 4.7 x 4.7 x 4.7 x 4.7 x 2 = 11,375:1

Anyone else think anything much lower then 120:1 with anything bigger then a 4 cyl is just a waste of time and money, and just makes for a bigger heavier hunk of trash?

Is it really worth it to have two 2 to 1 NP205s weghing in at close to 400 pounds when you could just use 1 Atlas that has 4.3 to 1 and only weighs about 150 pounds?

And the two 435s can't be doing him any favors either... What's one of those weigh? his truck probably outweighs a fullsize... Sounds like a recipe for breaking shiat if you ask me (even though you didn't :flipoff2: ).

with that much gearing he could plow the back forty while running a lawnmower engine

gear reduction is just like having suspension flex was a few years ago when no one understood it. this guy probably read that you could never have enough gearing and went overboard with it, just like all the gimicky ways to get useless wheel travel that are around these days ....

totally useless. too much weight, and gee looks like hes got a nice flat belly to the rig :rolleyes:

even if it was given to me i wouldnt want it. well maybe i would take the parts from it and built a different rig.

i seriously doubt he even wheels it, at least hard or often. theres no way that a drivetrain like that would last. a D44 front axle with that much gear reduction? hell you could break a 44 front with 3600:1 and a bike crank for power!

not to mention how clean all that :rainbow: blue paint is :rolleyes:

Am I missing something??? How do you fit 3 trannys and 2 205s under a ranger? wouldnt that bew like 6 feet with the adapters and such? then you move the engine BACK? Is that second case solid mounted to the real axle or what?

You guys are forgetting, it is mid-engine.

The engine is mounted backwards. The three transmissions and first transfer case are inline. The first transfer cse is to change the direction so that the second can send the power to the wheels. The driveshafts are LONG and almost parralel to the ground. Absolutely zero u-joint bind. The radiator is in the bed as are two transmission coolers. I'll try to find out who he is and see if I can get more info on this cool truck.

Well considering that I was actually standing beside this truck and talking to the owner I'd say that I'm in a better position to comment than you are. This is not a pretty truck by any stretch of the imagination and from the look of it I'd say it has seen plenty of hard use which can't really be said for anything that you drive can it?

fine but i would still have a 75:1 crawl ratio with a good strong 4 speed and a healthy V8 than 3600:1 with 15" of ground clearance under all those cases. its cool in theory, but its not practical or useful. thats why i said it was :rainbow:

i would have taken all the time and money that he put in to that right and built a nice stout FJ40, EB, Land Rover, or CJ5 with a 383, SM465, and a 203-205 doubler. simple, effective, good ground clearance, proven, strong.

With that reduction.... what do you need brakes for? Just leave it in gear and let it idle.

samuraichris, I have two SM465's hooked together. They yield a 575:1 final drive with the np205 and the 6.72's in the rockwells. I will agree, that much gear is useless 99% of the time, but it is cool when you get to use it! The front trans is for a married 205 application. The only thing special about the 2nd one is the input shaft. I had it cut off and a 1 3/8"x10 spline shaft machined on it. This is the same as the output on the front trans. Now you can use the factory transmission to t-case coupler to join the two shafts. Machine a plate to fit the back of the 1st trans, machine a plate to fit the front of 2nd trans. Cut tubing for the length between two plates and weld it in. I think it added 20" in total length, and about 250 lbs. once you get used to that many gear possibilities I think it would be hard to go back to a single 4 speed.

I used to have a 4-speed /three speed combo in my Jeep, now I have a dual 4 speed setup and I agree it is weird driving with only one tranny now

I was thinking everyone had forgotten the mid-ship motor..

The transfer cases are probably rarely all shifted into low-range - and depending on how it's all routed, it may not even make for a compound low.. you could mount a '205 backwards and get a 0.5:1 OD..

My neighbor builds dune-buggies for fun. Last one before his current (502 Chevy 4x4 live-axle coil-over.. ) one had a ZZ3 crate 350 hanging off the back of it, with a TH350 (I think) running to a transfer case.

The T'case was only used to re-route power down to the rear axle - the engine was sitting so the waterpump was pointing at the guy behind you at a stop light.

He probably didn't even have the shifters hooked up to make it possible to get into low-range.

Of course you probably think it's stupid because it was a light-hearted knock on you. But I don't think it was completely unrelated.

The truck in question, which you eliquently stated is
cool in theory, but its not practical or useful
could be in fact both, practical and useful, to the owner. You however do not possess the knowledge to make that judgement.

Regardless of differing opinions it is a neat engineering feat, which may have been the purpose for the build-up, you simply do not know.

Opinions in both directions are obviously to be expected on this board, but I ask you- Did anyone ever ask what you would've built instead? If they had I could see your reply
i would have taken all the time and money that he put in to that right and built a nice stout FJ40, EB, Land Rover, or CJ5 with a 383, SM465, and a 203-205 doubler. simple, effective, good ground clearance, proven, strong.
But... Since that question wasn't asked I was confused by why you felt it necessary to say "I would've built this instead". So perhaps you could save the stupid comments and simply answer my question about why you felt it was necessary to include your "I would've built this instead" comment as a reply to this post.

Could you also answer this question I'd say it has seen plenty of hard use which can't really be said for anything that you drive can it? because from your big talking attitude I was assuming you had some killer trail rig, was I wrong with this assumption?

05-01-2002, 09:45 AM
Is that "come on napolean complex" directed towards me?

I didn't think I was being rude, obnoxious or threatening in my response. Please explain how I was?

I just get sick and tired of listening (both here and in person) to people talk about how they would've done this, or would've done that, that's a waste, it sucks, blah blah blah. When we all know that most of the time the person talking wouldn't have had the enginuity to think of what they are critisizing themselves, and they also don't have a rig with all their "would've"s done to it. We can put all the "would've" dreams in one hand and sh!t in the other and see which fills up first.

It's just a pet peeve of mine when someone talks sh!t saying what they would've done would be better, but then they don't even have the "would've" vehicle to back it up.

*Rant Off*

By the way if the napolean thing wasn't directed at me (which I'm sure it was) sorry for the rant. Also the login is actually my dogs nickname- but it describes me as well I guess.

seems to me to be a useless setup, if you actually wedge a tire something somewhere has to give, the torque going into the last transmission has to be insane, probably take off the input shaft.
I would like to know how they are mated up though as a dual tranny setup would be nice.
