lsd (again)

[sonsters]

ok so im needing an LSD is this a good one? if not LMK which is... thank you!!http://www.z1motorsports.com/3...=2397

Get the Nismo LSD. It's only $773 from Tacoma Nissan.

http://www.nismoparts.com/catalog/?section=382 It's about 1/2 way down that page.

I priced one out for installation through Nissan, and it was $390. to install.

It's adjustable in 60, 80 or 100% ratios, and will be a little more friendly as a daily driver.

ah sweet man thnx dude!!!

[sonsters]

and thats all ill have to buy to convert my base model to the lsd?

[Beancooker]

No problem. I was planning on getting that, until I found out that I did have the preformance wheel and tire package, which also included a VLSD. Would rather have a clutch style, but VLSD isn't bad for free.

[dasoupdude]

I'm looking into get one of these too, seeing as that I have a base, i hate open diffs.

I'll just go weld them spiders and save me the money. (yeah right)

[sonsters]

ok so whats clutch style mean? like it disengages when the clutch is pushed in?

[Slider4105]

The clutch type LSD responds to driveshaft torque. The more driveshaft input torque present, the harder the clutches are pressed together, and thus the more closely the drive wheels are coupled to each other. With no / little input torque (trailing throttle / gearbox in neutral / main clutch depressed) the drive wheels are still coupled somewhat as the clutches are always in contact to some degree, producing friction. The amount of preload (hence static coupling) on the clutches is determined by the general condition (wear) of the clutches and by how tightly they are shimmed.

The viscous type is generally simpler, and relies on the properties of a dilatant fluid - that is, one which thickens when subjected to shear stress. Silicone-based oils are often used. Here, a cylindrical chamber of fluid filled with a stack of perforated discs rotates with the normal motion of the output shafts. The inside surface of the chamber is coupled to one of the driveshafts, and the outside coupled to the differential carrier. Half of the discs are connected to the inner, the other half to the outer, alternating inner/outer in the stack. Differential motion forces the interleaved discs to move through the fluid against each other. The greater the relative speed of the discs, the more resistance the fluid will put up to oppose this motion. In contrast to the mechanical type, the limiting action is much softer and more proportional to the slip, and so is easier to cope with for the average driver.

I'd take the quaiffe over the Nismo in a heartbeat, and cliffnotes, cluthc type holds the drive wheels together till the brakeaway torque is achieved, viscous slips first it's the slip that engages the the lsd

[sonsters]

why quaiffe?

[dasoupdude]

It acts normal under normal conditions, until you really start pushing the limits.

I am at work right now, but have a great article on LSD's on the PC at home. I'll post it up when get home tonight.

quaiffe has been the dominant LSD in motorsports for years, they are tunable and rebuildable, and I'd be willing to waer quaiffe rebuild kitss are cheaper and easier to get ahold of than the Nismo pieces which as far as I know are still sold as individual friction disks and shims, Nissan has a history of running short on R200's and parts
