JBones's Silver Bullet B6 S4

I think it was a fixed lsd and it was on a 240. Where did you find the front one? I’ve only seen the rear one. Either way though it definitely sounds like a good purchase. I don’t exactly expect my stock one to last very long after I get my car back ;D. How long did the install take you?

It sounds like that car had either a spool or locker. Both of those are pretty aggressive for a street car.

I sent off my front diff to wavetrac for them to make a lsd. They did but there were other problems along the way before I got the finished lsd unit in the car. Earlier in this thread I posted about it - just go back a few pages and you will find it. The front unit is listed on their website now: http://www.wavetrac.net/application.htm

The factory diffs are strong and I doubt that you will have any issues with the stock ones. It would be a good idea to change the fluid out if you haven’t done that before. I changed out the stock diffs because I could and you can get away without doing it. It is fun being able to go around corners with no understeer though.

The install took me a few days. Either way the rear diff or transmission has to come out to install the new bearing outer races. Also the new bearings have to be pressed onto the lsd and the ring gear has to be heated up to be installed onto the lsd. There is no point to installing a new lsd and reusing the old bearings. You also need new bolts for the ring gear because they are stretch bolts.

Locker lsd, there’s the word I meant to use [facepalm]. Exactly rx, it was crazy aggressive for the street. I’ll need to talk to JHM about there’s. Still no word on an eta for my car yet. I’m gonna try and pry some information from them on Friday me thinks.

In all likelihood that would have been a clutch pack LSD versus a torsen unit. The clutch type LSD’s can make noise depending on the brand and if it was broken in properly. My guess is that the diff was not broken in properly, hence all the noise and in some cases, shuddering.

Spools or lockers, as Jimmy mentioned, are too aggressive for the street and are typically only used in drift/drag/offraod vehicles. They do not permit the wheels to rotate at different speeds from one another.

Unless JHM are working on a second type of rear LSD, the current unit they are/will be offering is a torsen unit and the first unit was already installed in my car.

safe

p.s. +karma for your ownage last year in the offset argument

outch …. did you run 1 pass at least before it give up?

Congrats on the new pr! Thanks for info on the wheel set up and JHM sc.

That’s great news! I wonder how JHM unit compares to the Wavetrac JimmyBones runs?

ahahah Thanks Saki!
Honestly I wasn’t trying to own anyone. It was a great idea of a thread as I was/still is making up my mind for the track set up. Unfortunately, some people like to put others down for no reason and try to discredit informative posts based on their personal bs and not facts. He didn’t have a single valid point to argue with, sigh…

Interesting. I remember Jake telling me it was a clutch type so do you have any more information about the torsen setup that they are using? Anyways I hope that you get to enjoy that LSD around the track.

It gave up on the thirteenth pass. So it held up for 19 drag strip passes and almost three hundred miles.

Depends a lot more on the adjustment(s) than the brand. The bigger problem is that most people just install whatever they are sent, without realizing that a clutch type diff is, by nature, adjustable via turning plates around, if not also adjustable for ramps. If you leave it in the factory, full stiff setting, and if you bought the 2-way diff, then yes, it will very likely be too tightly locked/preloaded for the street.

Wavetrac/Quaife/Torsen/Helical/ATB whatever you want to call it are great for the street. They have little preload, so they don’t tend to bind under parking lot maneuvers until you get the wheel turned very far, but they still lock up when torque is applied. They’re not as great on a road course as clutch types, but if you’ve never spent time on one then it won’t be making a difference for you, and they’re still way better than open diffs. Also low maintenance, so they have always been my choice for street or dual purpose cars.

I’m only basing this on what Keaton has told me. I would prefer the clutch type but a torsen is better than nothing.

Quite true. That said, different brands have different numbers of discs and factory settings and regardless of the brand or setting, an improper break-in will still result in unwanted characteristics.

I don’t believe I have ever said anything about the LSD other than talking about one being in the works. I don’t know very many details on it, as I am not involved in the R&D on that product. Keaton would be the one with more information about that product.

the rematch…
