Alright, i've never ridden in a car at a drift event with a welded a diff. Nor have I have I ever seen a car with one. I always hear people talk about "just weld your diff!! don't pay tons of money for a slip" I can't help but knock these guys for trying to find a cheaper way out, and that the mentality of "can't afford 500-1000 for a slip, so just weld it" runs accross everyone that tries to claim that welding works just as well as a 1.5 or 2 way. But I never researched to really find out the truth behind welded diffs....
So, any input on welded diffs?! I want to konw the truth....
If this is a repeat post, sorry..

Welded differentials?!?! seriously?!
Re: Welded differentials?!?! seriously?! (FriedEGs)
It's called SEARCH!!!!
Well, in any case, I know that there is a guy on zilvia.net who sells these, think it's under the name LocDifferential or OpenLoc or something similar. There's people who drive on these daily - always locked. Good enough welding and it "shouldn't" fall apart.
In my personal opinion, doesn't seem like the safest idea to always run locked, but there are those who actually use these and they learn to adapt to it. Be prepared to spend some money on tires... but that's the side effect w/ nearly all lsd upgrades for one reason or another .
There's seriously a lot of threads on this. Don't make me hurt you, hehe.

okay, i did do a lot of research.... but I couldn't find the answer that I realized I need to ask.... A 2 way is "locked" full time right?! accel and decel. (1.5 accel locked only) Does the 2 way allow any slip at all for low speed turns to keep the inside wheel from spinning?!!
OR rephrase..I still haven't found the answer to this...
What is the difference between WELDED and 2 WAY?!
if there is a difference, what would be the pro's and con's?!

If you did a lot of research, you wouldn't be asking such a question. BADDDDDDDD.FriedEGs wrote:okay, i did do a lot of research.... but I couldn't find the answer that I realized I need to ask.... A 2 way is "locked" full time right?!
lsd = LIMITED SLIP differential. It allows slip based on certain conditions and what type of lsd you have, which you should SEARCCCCHHHHHHH.
A 2 way lsd will keep you locked the most, but not 100% of the time. Much more drift happy than 1.5 way lsd, and vlsd, etc, but still good for handling - more predictable than an open diff for example.
A welded diff is basically - no slip differential. Great for drag racing though, just not for turning.
I'm too nice to you, I'm not going to answer any more questions until you seriously do your research ....

Re: (Florida240sx)
I think when dude above was talking about wheel hop, he meant with turning, not going straight... but, i'm not sure....
anyway, brokearse, I think you just summed up everything i talked about already in this thread, so don't think you just offered assistance, and trying to be "nice."
Sounds like you think you know what your talking about, but I simply asked a question, and that was: how a 2 way is different from a welded diff. so far no one has answered that, or given a link that shows something.
Anyway, prove to me you know what the difference is, or how a 2 way works to allow slip when needed... That's my question....
If, I did my research completely, I wouldn't be asking, now would I? Prob is, I don't have enough time to look...

go to http://www.howstuffworks.com and look up "limited slip differential". It should have the answers to most of the questions out there.
Basically, an open differential tries to keep torque on both wheels equal. When one wheel slips, the torque experienced by that side of the diff will be less than that of the other side. When this happens, the diff tries to transfer more torque to the side experiencing less torque. This means that as long as one wheel has no traction, all the torque will be directed toward that spinning wheel. You can imagine why this is bad if you want to corner hard- your inner wheel will just keep spinning and the other wheel won't be providing any power to move forward. An LSD solves that problem by providing that freely spinning wheel with torque via viscous fluid or clutch discs. This will allow power to be transmitted to the outer wheel.
To answer your question about the difference between a 2 way and a welded diff, the 2-way will provide that "extra" torque on acceleration and deceleration to keep the speeds of both wheels relatively close to each other if not the same (i'm not exactly clear on that part yet). A welded diff will keep both wheels the same speed no matter what. People say it works the same as a 2 way diff because essentially it does....during drifting or whatever (any condition where one wheel would normally spin freely). Both wheels are kept from spinning at different speeds. However, during normal driving, you can't have them going the same speed or else one tire will always be slipping since the the inside wheel must travel a shorter distance than the outside wheel during a turn. That tire always slipping is why people go through tires quickly with a welded diff.
Hope this helps and I hope i'm not wrong :P If I am someone PLEASE correct me!

Re: Welded differentials?!?! seriously?! (FriedEGs)
I have been running a welded for a few months now, yes you get wheels hop on slower turns, because instead of the diff slipping, something has to give, and it becomes your tires, so they make a chirping noise around small corners. It also creates a ton of understeer in turns, but so does a 2 way because it locks under decel, and accel, but the welded probably even more. It isn't ideal for auto x, track racing, or anything like that, I would go with a helical or something of that sort if I were to create a track car, and I still might someday, but for now, I am into drifting since it is the cheapest way to get onto the track and be competative right away, provided you have skill.
welded does have wheel hop on slow turns, eats tires, although if you drift, it you wont really notice eh? It can be dangerous, but only when you drive like an ***, I've only had problems once, it was wet and I was late for something, dont remember now. Otherwise, ive never ever drifted on accident, just dont be stupid. As for snapping axles, I have heard of it but never from a primary source (on S chassis), havent experienced it, so I keep a spare at home just in case, but I dunno, maybe if you are using like a 255 tire, but with 195s im using or like a 215 i know a lot of guys of 17s use, i havent heard anything from them. I suggest it if you are really into drifting, if not, buy a vlsd or something, if you have money i would definately recommend a real LSD.

Mine's welded....only time I have problems with it is in parking lots when turning the outside wheel slips, but for high speed cornering and drifting it's amazing I highly recomend it over a 1.5 or 2 way ltd slip. and if you know what you're doing when you're welding it will not break. I put 250 HP through mine and drive it HARD and my weld hasn't broken after 9 months. I paid a ticketed welder $100 to do it.
