Limited Slip Diff

[MATT BLACK]

Fitting one to the Clio TT this week - will be up and running for weekend - got one from Quaiffe for £470 + vat !! and thats for a 6 speed vw box !!! I think there more money for clio 16v and 172 ones. If anyone is interested call em on -

QUAIFFE ENGINEERING 01732 741144 ask for matt.

 

[Guilbert]

they make gear boxes as well dont they?

 

[MATT BLACK]

Yes mate - they specialize in allsorts of transmission parts

 

[Phill1978]

why arent 172s or 182s fitted with them as standard ? do they make the car more tricky to drive if your a novice, reduce understeer ?, twitchy on bumpy roads ? or just to pricey to fit so they use a cheap traction control software instead

Pricey and will transform the behaviour of the car so in a way you will get more traction in the front so it becomes even more tail happy than standard! Very tricky situation for a novice!

 

[Guilbert]

Do they do club discount??

 

[Fred@BTM]

theyre not quiet either

 

[stu8v]

The only difference you would notice is maybe a little more torque steer.

All this talk of being more noisey and more difficult to drive is crap and usually from people that have or will never have driven a car fitted with one.

Tail happy PMSL utter rubbish!

 

[Slotter]

Dont they make the one thats standard eqpt in the Focus RS?

And he does not know that we are talking from experience and we know how to drive!

 

[bsimmer3000]

didnt all rs turbos also come with lsd?

 

[entjm]

what is an LSD... i knwo what it does but not how or what it loooks like...

is it an internal gearbox part?



Just to check i do know what it does... it stops one wheel getting all the power if it spins up by distributing the force to both wheels?

 

[entjm]

if anyone else is interested theres an explanation here...

http://auto.howstuffworks.com/differential8.htmhttp://auto.howstuffworks.com/differential8.htm

matt, out of interest what type of LSD did you get?



edit... just read about the different types of LSD, guesing its got some sort of clutch in it? thougha torsen diff soudns quite hardcore

[ChrisR]

Torsen diff standard on Rover turbos, Escort S1 turbos had them as standard, not S2 though.

 

[clarkiev6]

lsd... very basically ...will keep some of the drive to the wheel with NO traction...hense the steering feels more twitchy...where as a normal diff will take ALL the drive away when 1 wheel loses traction..

hope that simplifies things..

 

[stu8v]

RS turbos had a viscous coupling not a ATB type.

The noisey and aggresive LSDs are the plate types, a correctly fitted ATB diff will not be anymore noisey than the std type.

dont think that quite right... i think it give drive to the wheel with more traction? instead of giving the wheel with no traction all the power like on a normal diff.

(not that im an expert but from what ive been reading)

Thats correct for an ATB.

A plate type only gives a small amount of wheel slip before effectively Locking so both wheels turn at the same speed.

 

[entjm]

i dont know why but i think an LSD is one of the things id really like on a vehicle, above a lot of other things. the amount of times ive had a wheel spinning in my 1.4 and cant get traction it must be insane in a cup with a sh*tload more power!

 

[Floodie]

wow how times have changed.. back at school used to be able to get "an" LSD for around a quid

 

[16v_jon]

Im getting one phone them this morn!

If both wheels turn at the same speed you will literally steer off the road on corners. What it does is that it allows limited speed differential between the wheels so that the outer wheel turns at a faster rate than the inner wheel; hence the name limited slip

 

[Phill1978]

so which make are noisy. how is it to drive normally and how is it down Bumpy B roads at mid to high speeds ( i mean yorkshire bumpy with cacking great big dents all over the road)

 

[MATT BLACK]

ive driven my mates 260 bhp turbo scirocco with a Quaiffe LSD - its not noisy, it handles perfect and launching it from a standing start is fantastic..........all the above is nonsense.

Well I have the gripper on mine and it is great, awesome grip,

and it is noisy. The above is not nonsense, it all depends on its type

 

[clarkiev6]

i have a lsd in my hillclimb 5 turbo made quite a difference to the driving characteristics... better grip and start line speed...

bit noisy but not too bad..

it is nonsense mate - in the VW / audi gearbox the quaiffe diff is perfectly smooth with no side effects.

I think you will find the Gripper is a form of locking differential, and as such enables you to drive with only one driveshaft (such as finishing a rally stage) if it gave any amount of continuous slip this would not be possible.

So what it does is that it allows limited speed differential between the wheels so that the outer wheel turns at a faster rate than the inner wheel up to a point then it locks so both wheels turn at the same speed. Its this action that is noisey and pulls you all over the road if you hit undulations.
