twin engine jeep

[Kenny]

ok guys, let's put our heads together on this one, and see if we can figure it out. I want to put TWO inline 6 + 3 speed tranny in a 66 jeep gladiator. i want to mount one engine in the bed, mounted to the frame. unfortunately, the engine and tranny together are too long to mount normally. My question is, if i mount the engine, and turn the rear axel 180 degrees and run the rear axel from the front axel shaft, how can i make the wheels turn the proper way to drive the vehicle.

Is this even possible?

I know this is a wild idea, but i want to have a very unique FSJ. I have a donor truck that is only good for the engine and tranny, and the gladiator will just rut away if i don't fix it, so neither truck is being ruined.

[trssho]

Ummmmm, I would rank that as nearly impossible.

Oh, welcome aboard!

do a search on the web for tommy ivo he use to run top fuel dragsters in this fashion twin engine and all hes nick name was tv tom i saw him at irwindale and orange county in the late 60's aaahh yes rember the hemi under glass ????????

A new member...and he's a nut too! Welcome aboard Kenny.
Instead, mount an old Eldorado front wheel drive unit (with 500 cubic inch Caddy engine, of course) in the front and another one in the back. 1000 cubic inches and 4 wheel drive...that set up ought to kill ya!

[Kenny]

read plenty about tommy ivo in Hot Rod, his engines ran backwards which is way over my head, but thanks for the suggestion.

Keep the ideas coming guys

[gsmikie]

all you have to do is get a cam grinder to cut the cam for reverse rotation chev had some from the factory i had one in a pick up 427 tri=power had like a 500 lift baby would get it or you could use drop out diffs and rotate the 3rd members or swap front for rear and have rear steering or or or or etc etc etc etc ..anyway welcom ideas will keep you up late..........

Since you're running a an older truck, it probably has the D20. If you could rig it up with a rear PTO, you could hook that up to the output of the transmission you mount in the rear and turn it into an input shaft. Plus, you could engage it at your leisure.

Synchronizing the shifters would be a good trick if you're running manuals, though dual hydraulic clutches could be run off the same master clutch cylinder.

[Oracle]

how you going to carry enough gas to feed this thing? LOL

[Kenny]

i had the idea of using the rear engine as the main engine, since running 4wd all the time isn't healthy. the front would only be switched on when the extra power was needed, or just to show off
:-P
I think I can synchronise the shifter and clutch, right now I'm gonna try and figure out how to plumb the thing, I'm tempted to mount a second radiator in the tailgate, and run extra long radiator hoses, using black heater hose, and use an aftermar

Still trying to get the drive solved, so keep the ideas coming. it will be simple to operate the engines, since both are carburated, and have points type ignition

[BigChief]

Your a nut,I love it, why be normal.Any ways, check around with those mud pullin guys, they run lots of multiple engine setups.If you have a D44 rear, maybe the reverse cut gears from a front ford would work.

[Midnightwagon]

geez i like your style welcom aboard and i think rrande is right your a nut but in a good way i swear((whisper)i think oyuhave to be a nut to obsess over an old thing like we all worship) you could run both at an angle with a driver side drop rear nd mount the front of the engine to the pass side close to the framerail

[rawdave]

how about using two transverse mounted caddy engines from a front wheel drive v8 caddy?

[johnwaynejeep]

WOW...REALLY WOW

[Shake N Bake]

Hmmm...seems like a LOT of work smile.gif But I like the way you think...

But have you ever thought about making a 516cid V12 out of 2 258s? smile.gif I betcha it could be done (with LOTS of money and tons of custom parts...)

Here ya go:

Get a driver's-drop and passenger-drop front axle, cut both down the middle, then weld them back together so you have two pumpkins in the front. For the rear, get two Quadratrac-offset axles, and again, cut down the left-side of one of them to use the shorter-side axle from the right of a QT housing, then pull the tube from the other side and the long-side tube from the other axle, figure out how much tube you need to connect the two pumpkins for your truck's width, and then press that much tube between the two (maybe gusset the housings for strength). Lincoln-lock all four differentials (you'll also want them to be the same ratio.

Now, mount your two engine/tranny/transfer-cases side-by-side, BOTH in the bed. Use a Bronco D20 behind the left-side (again, swap in the same reduction gears as the other transfer-case).

Now you can power the left-side wheels from the left-side engine, and the right-side wheels from the right-side engine. Maybe run a large chain around both rear output shafts (adapt an external drum brake as a hub for a sprocket) to keep the powertrains synchronized.

Two engines, two transmissions, two transfer-cases, four driveshafts, four pumpkins: Heck, you'd have twice the truck of anyone around! :D

I also want a picture of the inspectors face when you go to get this thing registered... ;)

[Gwamp]

Hehehehehe.... this is too cool. I hope you manage to put something together!

[Kenny]

ok gang, here's my next question.

What is the maximum effective angle i can have the driveshaft from the front drive of the rear tranny to the fork on the rear driveshaft? I need to know a safe number, so i know how high to mount the rear engine.

Secondly,how can i check the gear ratios in the transmissions, and the axels, to make sure everything will be turning the same speed.

thanks for all the comments so far, keep the ideas coming!

[rustywag]

When two motors are mounted in a boat 1 0f them is reverse rotation.

[jode]

Bob...now THAT is an idea! Then you could manually control the throttle to each and turn it tank-style! ...unless the diffs were welded (which I think you siad to do... :(

[BIG BAD JON]

Bob has a pretty good idea there! By the way Kenny, what state are you in?

[Tad]

Uh, I am just at a total loss here, welcome and ???? :eek:

[Bluesky4x4]

Build it and they will come.....the police that is. smile.gif .

Taking a hard look at it, would you really go much faster with two engines than with one? Surely is would be a bit faster because they would split the rolling weight of the vehicle, but your not doubling horsepower to one axle. Your sending the same amount of horsepower to each axle, just as if you had one engine and one axle. I would just set it up with your regular drive engine for going forward and your second engine for reverse. Think about 5speed forward, 5speed reverse and massive burnout capabilities (or frame ripping capabilities).

[mdill]

Someone has way to much time on his hands !
Are we alking junk yard wars here ?

Mike D.

[Kenny]

The point is to not go faster, but to have more pulling power, and get massive ammounts of attention. When both engines are switched on, the truck will have twice the power, because instead of 1/2 the engine's power to each axle, each engine has to power only one axle.

I am in western PA, and looking at it, i won't have to have the vehicle re-inspected to drive it, cuz i allready have the title in my name. All that needs done is to get a state inspection sticker, and that shouldn't be hard.

Keep the great ideas coming!

[Kenny]

thanks for all the great info and ideas gang. does anyone have a 66 gladiator townside tailgate?, it's the only thing on the truckk that is missing, other than a window regulator, which i can salvage out of another vehicle. I'm hoping to start on the transplant this winter, we'll see how it goes

[bill tomlinson]

welcome friend
awsome! just had the same dream last week. if you had seperate engines for front and rear, you'd seem to have no need of an xfer case. get two gm 3600 v-6 front drives (buick, pont??) and drop them in (can you say project from h#ll??) the linkage for the auto trans would be easier and i THINK the rear unit would fit in the bed without eating any of the cab space.
