What does LSD stand for?

damn, im too late for this one, i was going to say Liquid Salty Delicious

Not all LSDs function this way, some require a certain torque resistance between the spider gears before it will start limiting the slip, helical limited slip differentials are like this. If you were to put a car equipped with a helical LSD with one wheel on ice and one on concrete, the wheel on ice would spin because there is not enough resistance from the ice to push the pinion gears against the housing and limit the slip. If you know anyone who has a helical type LSD, then put their drive wheels in the air and the transmission in gear. Spin one wheel, notice the other wheel spins the opposite direction just like an open diff. In any clutch type limited slip they would spin the same way. Quaifes (helical LSD) function like an open differential going into a turn and once the resistance torque is reached (which usually isn't much ~20lb-ft) and the pinions start pushing against the differential housing, it starts biasing the torque and limiting wheelspin, providing a smoother transition to oversteer, without it tearing the wheel out of your hands like a clutch type would.

so, how is the steering wheel going to be pulled out of my hands with a KAAZ clutch lsd? to bad im not FWD...

All yall ignant!Any fool knows it's a Limizzle Slizzle Differizzle! :pimp

clutch types lock both wheels into spinning together. if it's a one way clutch, then it will only lock them under acceleration. if it's a 2 way, then they'll lock under braking and acceleration.

So say you enter a turn with a 1 way clutch type. you're fine until you engage the throttle for heavy accelleration. the wheels begin spinning together, forcing the car to go forward not in the way you have the wheel spinning. i've always felt that clutch type LSD's were best for drag racing while VLSD's and helical LSD's were best for road racing. Oh what I would do for a helical LSD

HOLY ****! Someone who actually knows what they're talking about when it comes to differentials! That's hard to find on most forums.

I had a helical LSD in my ITR transmission. I loved it. And you're right, they do act as an open diff will when spinning the tires off the ground. Most people don't seem to understand that. Instead people think that's some way of verifying that you have an LSD. Well atleast on most Honda boards..

Well anyways, here's the insides of a HELICAL LSD. I broke the carrier on it so I had to replace it, I snapped the pic when I had it apart. Despite all of the gears in there, they are VERY easy to understand:



Everything's been explained already, just thought I'd throw up a picture.

Here's what a helical LSDiff looks like when it's chillin. For those that haven't seen one before:

in the Drift Bible I remember Keichi Tsuchia complaining that a worn out clutch type LSD feels like a viscous LSD. does anyone care to explain this?
