LSD

[Guest]

Hi All
I wonder if anyone can offer me some advice. My Elan runs a 1760cc QED
engine with big valves and 45DCOEs. It puts out a genuine 110 BHP at the
wheels. (Rolling road measurements by Grahame Hickman at Teme Valley
motorsport). Driveshafts are Spyder competition with VAG CV joints. Now,
the car has a 3.77 diff which is noisy and I want to replace it and the
inboard drive shafts before something breaks. I have a 3.9 diff I intend
to use for rebuild. It has been suggested I fit a Quaife LSD capsule
during the rebuild. I intend also to replace the rear shocks with Spax at
the same time. Question is, is it worth fitting the LSD or should I just
have the 3.9 diff rebuilt. I intend doing the odd sprint of hillclimb but
not regular competition. Any thoughts please?

Thanks
Nigel Furness

Sorry Nigel, but this won't be of much use to you (however, your post
reminded me to write).

I've come across 4 Lotus Elan diffs (ratios not yet known) - I can likely
buy the lot of them for $Cdn.150-$200. My question is simple - would anyone
have an interest in them? I do know that one of them is a 4.55:1 Salisbury
LSD (should be good for about 80mph!). I have no interest in these for my
Elan, but maybe some of you do?? I could query the fellow on ratios, etc...
if there is an interest.

cheers,

Nigel,

FWIW here is my personal experience with the Quaife LSD in my lightly tuned
(135 BHP) Sprint FHC using a 3.55 final drive:

The decision to put it in came when I encountered hopeless wheelspin out of
hairpin bends in a hillclimb race. The important point in this context is my
use of Avon ACB-10 tires. These develop so much side force that weight
transfer is considerable. This year I participated in the same race again,
this time with LSD. Result: no wheelspin any more combined with silk-smooth
action. In everyday use you don't even notice that there is a LSD. Very
recommendable if wheelspin out of corners has been an issue for you.

Usual disclaimer: I do not have any connection with Quaife except as a very
satisfied customer.

Cheers
Peter

Bill,

I am very interested in the 4:55 Salisbury unit. Is this a complete diff,
or just the center section? What are you asking for it? Where are you
located?
Thanks!

I have a Quaife LSD module that is used but in excellent condition that I
would sell for $350.00, about half the price of a new one. Let me know if
you are interested, even though it is a bit like carrying coals to
Newcastle.

Stan,
I'm in Toronto. its a complete diff. What do you think its worth (as I
said, I need to buy it from a fellow, but I know that, due to his situation,
it will be cheap. eg. I just bought a weber head with L1's, carbs, set of
rods, old shortblock for $500 from him)?

cheers,

Go for the Quaife LSD.It works very well and with out any bad manners that would require
driving changes.We sell loads of them and they are very well received.The only case that
a different LSD is required is when the car completely lifts it's inside wheel,then the
Quaife goes "open",like a standard diff and that requires a locking diff such as
Tran-X.This should never happen with an Elan .Regards,Jeff.

Bill,

I could be interested in the LSD unit or also a 3.77 or 3.55 ratio or all 4if that's what it takes.

FWIW the Quaife diff is not a LSD. It is a automatic torque transfer diff ( ATB) and as such transfers the torque proportionally to the wheel that works most i.e away from the wheel that becomes "light". It is far more suitable for a road car and come to think of it track, sprint and autotests ( gymkhanas here in SA )as it does not induce the inherent push or understeer of a LSD
I'd definitely prefer this to an LSD (diff or tablet )
Arno

[Elan45]

I choose the Quaife diff for my Eleven since I felt it to be the least harsh on the driveline. It doesn't add push at all, but I have had a wheel loseit on an oily track and spin almost like an open diff. (LR over turn 8 at Mid-Ohio, where that wheel was barely touching the track if at all).

Sounds like the action of an ATB diff. When one wheel loses all traction , as in completely in the air , the ATB diff acts like an open diff

I understand the Quaife is a torque sensing unit in which case it should beexcellent for your car.

I put a Salisbury LSD in my car since I got it cheap when I had the diff out for bearings, and it adds push to the car with the stock size tires.

Price sounds good -Ratio and condition determine interest. 4.55 for
street sounds too much. George

Hi All
Thank you all for the advice, I will go for the Quaife diff with my 3.9
ratio. I will report on my experience with it when fitted.
Thanks again
