Title: LSD , what are they fitted to..
Post by: pugtop on 17 December 2007, 00:58:25
Were LSDs fitted only to Cop spec MV6s or all MV6s ... ?? Any ideas??

No mate iirc they where fitted to all mv6's and also the 3.0 elite had a slipper in there to..

Some one else will back me up but im pretty sure im correct

Cool , i'm after an MV6 , seen a couple but not really had the chance to give them the'BEANS' if you know what I mean. The Auto one I drove had Traction Control though??? I have a Quaife LSD fitted to my 205 GTi Rally car and it totally changes the way it drives , much more traction on wet surfaces..

They are rare and were only fitted as standard to the Police spec cars......

They were NOT fitted as standard to MV6's or 3.0's

Aha , that explains the T/C on the Auto that I drove .... cheers...

No standard (retail) Omega has LSD. It was an option, but very rare to find one.  Ex-plod for a limited slip, and even some of them don't have it.

Most of the Omegas imported to Finland have had LSD as standard, so it is easy enough to find second-hand diffs with limited slip. And iirc all V6 models have TC no matter LSD or not

Hmmm, so I suppose I need to wait until it rains , turn off the t/c then give it a right boot full  ;)

Don't think you'll need a wet road to test for a LSD on a V6!  ;D

I'd rather have a slipper than TC. The Monza's have slippers as standard (the GSE models that is) and it does improve things no end. I find that if I get keen with my right foot such that the TC cuts in, the car just goes sluggish until it grips, at least with a slipper you can power away :)

Agree, the TC can be annoying, but still very useful in certain situations... E.g. on icy/snowy road when you put your right foot down to accelerate to pass someone it is good to have tc, but in the city it is annoying; I rather have it off and try to cope with slipping tyres and go sideways due to LSD  ;D

Hmm, seems liek you Scabndinavians get the LSD as standard , unlike us Brits that have to suffer with switchable one wheel wheelspin! How many MV6s in UK spec have got a slipper as std?

I had a 1999 auto mv6 which did have a lsd so I assumed they were standard. ::)

unless it was x-cop i doubt it....

As mentioned no retail versions had an LSD, only a few cop ones did....

Like T/C , I find ABS can be annoying on my works Transit , that really needs T/C though .....are there many LSDs around 2nd hand in the uk?

ha ha if anything the LSD give me less traction in the wet as its sideways at every corner. It does make the driving alot more interesting though. I wouldnt of considered buying an omega if it didnt come with one.

He He. I think the Westfield was on opposite lock for about 100 yds this morning after turning out of my road. Not so much ice as too much salt on the road. I suspect my viscous coupled LSD is a little too viscous at -3 degrees!

Spare a thought for my task coming on Friday -- I left my car at my folks' house last weekend (well actually all 3 of them lol) in anticipation of taking the bike down there on Friday to park it up for the winter. Long overdue I know. What I didn't anticipate was the weather hovering just above freezing all week, not exactly ideal conditions for a 70 mile ride on an R1 with semi-race tyres :o I'll just have to try my utmost to ride like a pussy, easier said than done!

BTW forgot to add, my MV6 doesn't have a slipper even though it's a manual, so it seems they're pretty unusual on retail models.

Best way to find if you have an LSD (apart from looking at the stamp, there is an identifier, can't remember what) is park up with one of the wheels on a grassy/muddy verge.

Pull off quickly, if you don't move very fast and start spitting grass and mud everywhere then you ain't got and LSD.

Also, if I remember correctly..........  Jack the back up, put it in gear and spin one of the wheels by hand.  If the opposite wheel turns in the opposite direction it's not an LSD, if it spins in the same direction it's an LSD.  Anybody back me up on that?????

Post by: pugtop on 18 December 2007, 19:16:45
Yeah that rule works for front wheel drive LSDs too... My 205 GTi Rally car has a Quaife LSD as said before , jack the front up , spin one wheel , the other spins in the same direction , my other 205 however doesn't have one and the wheels spin in opposite directions.
Title: Re: LSD , what are they fitted to..
Post by: psnimv6 on 18 December 2007, 21:18:25
thats not the case in the omega because mine has a slip diff and if you jack it up and spin the wheel one way the other spins the opposite  direction, i know in fords the slip diff does what you said but the omega has a different type of slip diff so this does not identify a slip diff hth

The quaiffe is a torque sensing diff, similar to the Torsen centre diff used by proper Audi quattros (not the Haldex rubbish used in the A3 and TT). The Omega one is a viscous coupling, so it acts like a normal diff until there is enough slip to lock up the coupling, hence it will behave like a normal diff when turned slowly.

I thought a viscous diff would behave as described but torsen and plate diffs behave as an open diff until enough torque is applied for it to lock. With the ex-Granada Cosworth diff in my Westfield (viscous) it's only just possible to turn one of the rear wheels by hand while holding the other one still. The certainly want to rotate together  :-/

A viscous diff will feel like an open diff if it's past it ;)

the omega is a plate diff, not viscous (well mine is anyway).

The best way to check if its got a working diff and a way that has NEVER failed me is.

stop, engage 1st, brake with your toe, accelerate with your heel and side step the clutch, slowley lift brake, pull away, look behind and it there is 2 black lines then its got a diff  ;D (this will also test if the cluch has much meat left on it  ;) lol)
