Ha Ha. Are you lost yet. Lets simplify the center diff for a second.

What its supposed to do, its side effects, and tuning it to get a whole assortment of handeling traits can be confusing.

Its a diff, It deos the same thing as front and rear diffs. They diff to.

When a car turns the left tires spin at a DIFFerent speed than the right. Thats why you need front and rear diffs.

Ok, now the front and rear axles also don't spin at quite the same speed. The action is less than side to side. Without a center diff the car would scrub in the turns. The center diff frees up the drivetrain so the car has better turn in. You lose a little exit steering(on power due to power flowing to the front) but that helps make the car easier to drive.

The side effect of the center diff is that it can send too much power to the front wheels. This is why AWD cars usually don't have a tendency to wheelie. To some this is a benifit. It hurts the cars acceleration though.

The hudy book is good for setup tips. I have never seen any success with less than 5000. 5-7 for buggy. Maybe 7-10 for truggy??

The best setup is to have a real loose diff off power for good steering. And to have a stiff setting for straightline accel. You have to find this balence with fluids.

An active, smart, or Bbf diff deos this. The trick is tuneing them so they don't lock up at the wrong time. Loose AWD in the turns and Tight 4WD on the straightaways.
