how useful is a center diff

[studcow00]

i know it helps acceleration, eliminates wheelys, and dosent kill the driveline if a rock gets stuck in your rim.

i dont know what else it is good for... i have the option to take out the center diff and I'm also worried it might make the buggy flip in turns where acceleration or braking is applyd (because i had a tmaxx, and if i hit the brakes or throttle in a turn, it would just roll, it could be the COG or the center spool) i will problbly remove the center diff for a little to jsut try it, but lemme know plz.

I thought you needed the center diff to get the "true" 4 wheel drive? How would you connect the rest of the drivetrain if you did take out the center diff? Just curious... Thanks

I'm guessing he'd lock the center diff. But I could be wrong.

A 1/8 buggy will just handle poorly on a track. You loose handling for turns and braking. But the COG is so low that it won't flip and pull wheelies like your maxx did.

I don't have mine locked, but I run 50K oil in it and it made my handling suffer quite a bit. When I want to turn at speed, I have to jab the brakes pretty hard to get the rear to start coming around then peg the throttle so the rears dig in. When I had just grease (I think, it was stock HB) in the center diff, I'd turn the wheel, hit the gas and it would just follow it's nose. But most of my power was lost in the front all the time since the rears get more bite when your on the gas. The fronts would just spin all the time and it was annoying.

Since I'm a basher only, 50K works well as long as I plan ahead before a quick turn at high speeds.

That center diff helps transfer the power from front to rear. It's performance also depends on the weight of fluid in there and also what type of diff it is. Regular "open" diffs can be regulated with heavier or lighter oils.

As the subaru comercial goes ..."Transfers power from the wheels that slip to the wheels that grip."

By means of two solid drive shafts either side of the spur gear.

The center-diff also offer the following benefits:

- Better turning circle
- Tunable braking, i.e. 60% brake Front, 40% brake rear IF you have brakes either side of the center diff
- Torque spilitting between front and rear drivetrains tunable by means of silicon diff oil

Other useless info: Most buggies use/recommend 7000 wt silicone oil in the center diff

well, I'm going the rout of no center diff.

to solve the mystery of how I'm removing the center diff, I'm replacing it with a 2-speed >: ]

50k in a center diff? That is shock oil numbers. A good setup would be 3000 in the front, 7000 in the center, and 2000 in the rear. I am assuming it is an ofna since you are going to try a 2 speed?

 

[psunitro]

LOL, yeah but its 50,000!!!! NOT shock oil. I was running 30k in my truggy in the center.

I've seen as thick as 200k made associated. People are racing their LSP's with 120 in the center. Too much if you ask me, but they have had success using it.
