LSD for Autos is almost done
Some of you may remember that a while back, I posted about making an LSD for autos. Well, it's finally wrapping up soon. I get the prototype in about 10 days or so, then after I see how it works, I will start carrying these units. They are being made by Vitek Performance, but they will be selling them through me for the Maximas.
It's a clutch type differential, no it's not a phantom grip. We will be needing to do core swaps on these because the factory casing/housing is used. Pricing is still being worked out, but it's actually lower than I had originally though. Way lower than the Quaife, but that's not available for autos anyways.
And the best part is, there will be a lifetime warranty on these. Even drag racing is covered, so taking it to the track isn't an excuse for the warranty to be voided.
I'll have all the technical specs up in a few days, as well as the pricing. Email me at apsignworks@hotmail.com for more info.
BTW, if you start seeing Stillen with LSD's all of a sudden, these are it. I know that Stillen wants to carry the LSD's also, but for now at least, I get priority over Stillen for the Maxima units.

How will this compare with doing a swap with the I30t tranny with LSD. I assume it will be a little better in the performance area. I've located low mileage I30t auto's for anywhere from $725 to $950. Is this close to the price for the Vitek one?
Now we can all get a "Vitek Inside" stickers! lol
Thanks for working on this. I've really been wanting to LSD in my auto.

I wonder how much it's going to cost. Ahh, since I am just running stock, I probably won't ever get one ... I wish I would though, just for the fun of it (but fun come$ at a price
)

Performance wise, this will be better. It will transfer more power than the factory LSD. Plus it will hold more power than the I30 LSD, although I haven't really seen anyone blowing those up.
Pricing is still being finalized, but it should be below the $1K mark so comparable to the I30 swap.

Well, I go to the shop tomorrow to pick this thing up. It is finally done. I should have this LSD installed next week at which point I will give you guys details about the performance. Also, in the next few weeks, I will be going to the track to see if this improves my numbers any. Although the 1/4 mile is not where the advantages of having an lsd are, it should lead to some improvements there.
Retail price has been set at $1200, but the price from me should hover around $985 or so + shipping. It ain't cheap, but it costs so much to make that we can't sell it below that. Also, there will be a $250 refundable core charge. We need the factory cores for the housing. We're not just stuffing a phantom grip in there, don't worry.

A Valve body upgrade from mobiltec racing will not interfere with this correct?

And how will LSD help in a regular driving situtaion?
I'm Supercharged, and i rarely spin my tires. most mods don't affect low-end (Even a SC, unless you get a very small pulley).
Basically, I don't understand exactly what this does or what it will help.
Can someone explain LSD to me?
Thanks!

That also answers your other questions.

Basically, an LSD transfers power from the wheel that slips to the wheel that grips. When I was running a 100 shot of nitrous, my wheel would start spinning as soon as I hit it. Notice I said wheel as in 1 wheel? An open differential only really puts the power down to one wheel, and if one wheel starts to spin, things really get ugly. The benefits of an LSD is mostly for turns, you can take turns slightly fast and power through them since before the inside wheel would just spin, now with both wheel's gripping, you get acceleration instead. With nitrous, I think I could have gotten much better times because I would have had more traction. JIME has an LSD auto and look at his times... 13.1...

Also, personally (don't tell my max) I think the 4th gen looks a little more aggressive; perhaps it's appearance just says "mod me"!
Great job on getting a LSD done. I hope I can use it!

It will be done for the 5th gens very shortly. I just have to run the 4th gen one through the paces, and sell some of course to recoup my investment. From start to finish, I can get one done in 3-4 weeks from the time I get the core. The reason this one took so long is that we got jacked by the previous company involved in this, not only did they not deliver the LSD, they even kept the core I sent them. The new company I'm dealing with turned this around in 3 weeks for me.
BTW, is the Quaife available for the 5th gens? Because if it is not, we will develop one for the 5th gen manuals also. The reason that I started with the 4th gen auto only is that there is a huge demand for it. I don't want to compete against Quaife for the 5spd market, but if it is not available for the 5th gen manuals, then it will be done.
And after we do the 5th gens, the 2k2 will be made provided there is demand. But since the 2k2 already has the LSD as an option, we'll have to first see if demand is there.

In a straight line you don't spin your tires much, but corner hard and get on the throttle. If your car is anything like mine, it basically sits there spinning.
Basically mtrai760 explains it perfectly.

I tried gauging interest on a Quaiffe for the auto's a while back but the price from Quaiffe + the minimum order of 30 units was to steep.
If it's any consolation, i did manage to find out from the Altima's group that there is a small demand even from the auto owners. (2k2). Combined it should be good.

My car goes into the shop tomorrow to have the LSD installed. I finally got to see the completed unit today, very impressive. I should have my car back late thursday or early friday at which point I'll let you guys know how it is.
It's actually very fortunate that we had the problems with the previous differential supplier and had to switch. turns out the original one only provided a 70/30 split, up to 30% of the power goes to the wheel not slipping. The unit I have now provides a true 50/50 split. Don't know if that translates into better performance, but it should.
