Who makes off-roadable V-drives???

Who makes off-roadable V-drives?

I am accumulating parts/designing a budget desert buggy. . .mid engine/RWD IRS. . .I want to mount the engine right behind the seats with the transmission pointing forwards (manual transmission. . .I know the shift pattern will be funny, but it's just right to left instead of left to right. . .not hard). . .I originally thought I would just use a spare transfer case I had laying around to re-direct the output of the transmission back to the rearend by using the front driveshaft output, but then I realized that the output isn't centered and clocking it so that it would be centered would make it hang down really low which isn't acceptable. . .so unless someone can make a suggestion for getting a transfer case to redirect the transmission output back towards the rear-end and centered I think I'm stuck with using a V-drive, but I know pretty much nothing about them including who makes them.

Thanks!

Used v-drives show up on ebay fairly regularly, too.

Check out this build. It's a 4wd Class 1 / KOTH cross-over.

if its going to be IRS why run a V-drive? if you are going to use a solid rear end you could use a t-case, just offset the diff on the axle.

Looks nice BUT what is he going to do about the driveshafts rotating the wrong direction?

Run the axles upside down. :D

[stuckthrottle]

Why not run a transaxle?

[partybarge_pilot]

Well, cost for one.......

[stuckthrottle]

I didn't catch where he mentioned what engine he was planning on using. A (good) reconditioned bus box can be had at around 1000.00. Whats the cost of a good v-drive? Factor in power loss through all of it too...
Of course, if he was using something big, he would need a bigger transaxle and then cost would go way up.

why wouldn't a divorced Np205 t-case froma ford or dodge work in the place of a V-drive. just use th efront output and not the rear. They can be had for $250 or so and are strong enough for some Big block trucks.

The 9" will not oil the pinion bearing upside down been their done that.

you can put a oil slinger on it... or overfill it.



i still dont understand why he wants to run a v-drive on a mid engine irs setup. hook the tranny to the motor and than mount the diff to the tranny... no need for a v-drive!

It will nerver work????? Shannon Campbell just ran a 200 mile race with upside down 9" Just have to have the right people build your rear end. Look at the door!!!!!! He'll also be racing V2R

Currie makes high pinion diffs BUT I'm not positive how they are doing the ring and pinion on this rig. currie makes a ring gear just for the hi pinion case for standard rotation only. That was the last time I bought 30 of them. maybe they have a reverse rotation gearset now I don't know

If I was guessing its so he can have a shorter wheelbase than a behind the seat engine/trans/diff setup...

curries hi pinion 9" uses reverse cut 8.8 gears. they dont make reverse cut 9" gears. True Hi-9 is the only company that makes a "true" high pinion 9". shannan campbell runs his diffs flipped.

it seams with all the extra headache he will only be saving 6inches since you couldnt put the diff right up to the motor becouse of the drive line that would be snaked around the motor.

He'll just have to adapt a TTB to the rear, and run the offset driveline :D

I didn't wanna run an IRS and using a T-case means that my output to the rear won't be centered. . .not an option with IRS. . .

WOW!!! Expensive!!!


Why not run a transaxle?

Not a bad idea now that I know how much a V-drive costs!!! Could buy a transaxle for the cost of a V-drive. . .the whole idea was to keep this thing on a budget. . .the only area I wanted to spend "money" was on the shocks and then make sure I get used OEM parts that would be able to handle the power I wanted and upgrade to $$$ parts as I could save. . .I considered spending money on a Currie 9" IRS housing as well since I already have a 9" third member. . .

See above. . .with IRS I need a centered output. . .using the front output would have my output offset.

I may have to run a solid axle to keep this a budget buggy!!!

What about a big V6 (or 8) FWD car motor/transaxle? Nothing to work out but shift linkage. Caddy 472/500 anyone? Ridiculous torque, shouldn't mind 37's without a gear change. or something newer, tons of options. I built a single seater out of a spring 3cyl way back when with ATV tires. First project, and certainly a bit rough, but an easy way to do mid engine. A wrecked Ford GT would fit the bill Muahahahaha!

[atomicjoe23]

If I could get my hands on a GT engine/tranny combo that would be awesome. . .but even the big builders (street) are having trouble getting that stuff now!!!

I had thought about the FWD tranny thing, but there are so few manual FWD vehicles with a decent size engine so that they would have a tranny to take any decent amount of power any more. . .I haven't worked on them before either so I'm not really familiar with the layout. . .I wasn't sure if it would work with lining everything up. . .I should take a trip to the junkyard and do some crawling around it sounds like though. . .thanks for the suggestion.

Did it wrong then... :D

Exactly

It runs standard 9" parts with a custom pinion support.

cdc has it spot on. Everything is standard rotation 9" stuff (of course it is good stuff to begin with) and has a custom pinion support. If you have one handy grab it and look how it oils. Now just think of it upside down... close up most of the oil in port and open up the oil out port (it has to work in reverse).


That description is a little over-simplified, but it is accurate. There is a thread over at PBB about modifying your own pin support for proper flipped 9" oiling (http://www.pirate4x4.com/forum/showthread.php?t=395927).

Pic from that thread:

JR has been running that one for a number of years under 2 different buggies.



So many people in the rock sports use flipped 9"ers that Currie now has flipped pin supports ready to go. Then add in a little baffling to the housing to help guide the oil into the oil-in port and you have it made.


For extreme use, you could always go with a 9" oiling pump that the roundy-round guys use. Pinion driven and us could direct the oiling tube anywhere, including the oil res in the pin support.

Yep, no need for special reverse cut gears, just pay attention to oiling and it will work fine.

One huge benefit of the flipped 9" is the high pinion, makes d-shaft angles much better and keeps it up out of harms way. :cool:

[JEFFRPM]

I did all of the oiling stuff you have suggested the problem is not the oiling It's the gears running backwards " RUNNING ON THE HEEL" of the gears they build all kinds of heat and use up 30 percent more power hence the heat. When you run 500 plus horsepower to them for 5 or 6 hours playing around the ring gear gets cracks in the root of the teeth then It's only a matter of time before bang game over. the rock guys run for 15 minutes 4 times a day this V2R is going to prove my point on all the guys FLIPPING a 9". This also depends on how much horsepressure and the throttle angle these guys utilize.

With a rear engined rig, transmission pointed forward AND the axle flipped you are running in the correct direction and are on the proper side of the tooth. They are not weaker, it is only an oiling issue.

Guess you missed this post?

The flipped 9" has been ran in the last few KOHs with big success and have been beaten for the past many years in a multitude of rigs. Get the oiling right and they work fine.
