Got LSD?

[Jess]

I found a place that has a bunch of JDM VLSD's for $250 shipped. Im orderin one tomorrow 8)

[insert_car]

shiza, 250 shipped! thats niiiice. now STFU and put that turbo on you rich bastard! :twisted:

[Mitsubeatshi]

is that a clutch type or helical Limited slip?

[Jess]

Visious. I guess that would be considered a clutch type..i guess. im RWD dumb

Viscous is neither clutch packs or helical gear style.

Viscous type LSD's:
These are similar to the viscous LSD's used in some AWD vehicles. The
way these work is that a special fluid is used in the differential
which THICKENS when excessive slip is induced. Stators and impellors
in the diff make this even more efficient. Although there is a slight
delay in locking of the differential, they work very well and last a
long time.

Inside a viscous coupler as shown in the right hand side picture, there are many circular plates positioning very close to each other. Both drive shafts connect to roughly half of the plates in an alternating sequence as shown. The sealed differential housing is fully contain of a high viscosity liquid, which has a strong tendency to "visco" those plates together.

In normal condition, front and rear axles run at roughly the same speed so the plates and viscous liquid are relatively stable to each other. When tyre slip occurs in one of the axle, that means the alternating plates run at different speed, viscous liquid will try to visco them together. As a result, torque is transferred from the faster driveshaft through the liquid to the slower driveshaft. The greater the speed difference, the larger the torque transfer. As a result, limited slip function is implemented.

What you described would be a clutch type limited slip, wiggie.

[CPMaverick]

No it's not. :wink:

Maybe you need to go re-read how a clutch type LSD works. It uses a set of clutch disks that slip when torque is being transferred equally. When torque is only applied to one wheel (burnout), the clutch packs lock together and transfer torque to both wheels.

In a Viscous style LSD, the plates never touch each other. It's the fluid that heats up, thickens, and transfers power between the plates.

Yep, what the stunta said

The opposite of what you said; The clutches only slip when the wheels are moving (or trying to move) at different speeds. When torque is being transferred equally the don't slip, they might as well not be there at all. If they slipped when the wheels were spinning the same speed, they wouldn't last long.

They don't lock together either, they just have a certain torque that overcomes the clutch and then they slip. A locking-type is a whole nother story.

I knew that. I was just trying to start some contreversy..mmm.yeah.

I'll call the company with the LSD's in 3 hrs. I soo hope they still have some. Those things don't stay in stock long.

[Jess]

Just ordered w/axles. should be here by mid-next week :)

I dont know if wiggie said this already, but the older the viscous lsd's are, the less they work because the fluid loses its ability to thicken. :idea:

Yeah, ive heard this also. Im hoping that the reason for this is miles, and not years, as most of the JDM parts are relatively low miles
