Have good news!

Tom from TL Jaguar in the UK has fitted a Quaife LSD unit in a Stype housing, so the first hurdle is taken. He will install it on the car next week, will keep you posted.

 

Ahh, there may indeed be thanks givings

 

When will the car be finished? When will the kit be ready?

 

Wow! All those prayers chanting "Please let there be an LSD for the S-Type" are finally coming to fruition. Thanks for the update AVOS.

 

newbie lurker here, but what is Quaife LSD?

Thanks

 

Easy - use google

 

nicey nice

 

Hi,
Its a Limited Slip Differential.

Good news!

I have just heard that the install was a succes (quaife LSD unit) in an Stype. In case you are interested you can contact:

Tom Lenthall at TLJaguar in the UK +44-118 973 7779 )

 

I remember a while back that someone raised the issue of a limited slip unit potentially causing some issues with the stability control software?

Has anyone though about this and is there even an issue? At first glance I wouldn't think it could be an issue but ...

Sounds good! Who wants to be the first over here?

 

I'm not brave enough to be first, but I might be a very, very, veryveryvery eager second...

 

Sounds like a line from a movie all about puberty ...

 

Biloxi Blues? Porky's? Hee, hee.

 

Yes! Biloxi Blues!

 

I'll be first but someone is gonna have to buy me the LSD though. LOL Any idea if this is an existing LSD for something else or a whole new made for an S-type unit. If its for something else may be easier to source over here.

 

The LSD is a GREAT upgrade. I think it's impact on 1/4 miles times has been exagerrated a bit here though. The goal of a launch is minimal to no wheel spin. LSD or no LSD shouldn't be a primary concern.

 

For specifics on the LSD better to contact Tom, but I think not much customization was needed to the quaife unit to make it to fit the stype.

It works pretty well with traction/control / DSC, as that one only comes into action once a wheel is actually spinning, and that only starts after the ATB (Automatic Torque Bias) type diffs do there work first.

 

Can somebody get an overview of part numbers, source, and what exactly 'made it fit' means?

I'd like to consider seriously

I recently found this article http://importtuner.automotive.com/11...ial/index.html regarding LSDs. The article is actually intended to address the idea that adding an LSD will decrease HP to the wheels, due to increased rotational mass. However, their tests are very helpful.

The magazine guys had an in-house project Integra of some sort, and decided to add a Wavetrac LSD. On Day 1, they dynoed and ran the car several times in the 1/8 mile with the stock open differential. On Day 2, they did the same with the new LSD installed.

The car improved its average 60' time by .332 seconds, from 2.533 to 2.201 seconds. Its average 1/8 mile time improved by .349 seconds, from 10.15 to 9.801 seconds. I used an ET calculator (of unknown accuracy) to get an idea of what this would translate to in the 1/4 mile, and it shows a 1/4 mile improvement from 15.83 to 15.29 seconds. In order to try to assess the accuracy of this calculator, I grabbed one of my timeslips from last year and entered the 1/8 mile times into the calculator; after entering my 1/8 mile time, the calculator estimated my 1/4 mile to be .145 seconds slower than it actually was, so consider that for whatever it is worth.

A 13-second car is not going to see the same gains that an Integra would. However, it is apparent that there is at least some quantifiable improvement upon installation of an LSD. Considering these results, and how much torque we are producing, and how easy it is at the moment to launch with only one tire spinning, I can't help but think that the exaggeration is warranted...at least to some degree.
