LSD VS Non LSD

[gsboi101]

I was planning to buy a 90-94 awd and was wondering which is better, one with limited slip defferential or no LSD, and if i buy one without LSD can i still put one in it or i have to buy one with it? Dose LSD give u both traction to all wheel with the same engine power.

The limited slip differiential will give all wheels traction at the sametime only when your going straight. You can shave off a good amount of time in the 1/4 by just having a LSD. LSD has clutches built in so if one wheel is losing traction (Straight line) the clutches in the diff turn the other wheel as well. Anyway bottomline is get the LSD one, it will make a huge difference in traction (In a straightline). LSD's don't work when your turning, then its just like a regular open differential where the pinion gears on the differential pinion shaft move to compensate for the different wheel speeds.

Having an LSD is definately an advantage. Here are few links explain how things work.

Whoever gave me negative reputation is retarded, here is the "clutches" I was talking about.

Some people are just too much.

That is for a clutch type LSD. The stock LSD's are viscous coupling which don't work the same.

But the negative feedback is understandable, given the above. Not only do our cars come with VCs (not clutch-type limited-slip devices), but our VCs - like all limited-slip devices not controlled by a good computer - are just as active when the car is turning as when going straight ahead. Of the cars we all seem to care about, only the recent Evo has a center that snaps open when the car is turning.

In general, your post was almost entirely wrong, and didn't even try to answer the second of the thread-starter's questions.

1. 99% of people would say that an LSD center is better than an open center.

2. I've spent a good half hour trying to figure out if a VC can be added to a car that did not come with one. My guess is yes, but who cares about guesses?

3. All three of our diffs have a 50/50 split; that is why the power is evenly distributed as a default. A locked diff actually makes it possible for the split to become very uneven, not the other way around. Please read those two tech articles. One of the most common misconceptions is that a locked diff has a 50/50 split. In reality, a locked diff has no meaningful split, since the actual distribution of torque can change every instant.

Thanks for the all reply, now i got a really good understanding of a lsd and I positive that i will get a awd dsm with a LSD and burn my brother honda civic hatchback who prepairing mini me swap and then againe i'll probably still beat him even with a turbo. Thanks
