    Default Quaife LSD group order for GS/A!

    Hi guys,

    I am helping to organise a group order for Quaife to produce one of their Automatic Torque Biasing (ATB) Differentials for the Citroen GS/A gearbox.

    Advertisement


    Cost will be in the around 900euro per unit.

    This is being organised through Louis Barbour who is an agent for the Quaife 2cv LSD.

    I will be using it in my 2cv with LNA gearbox.

    Please PM me if you are interested

    Cheers,

    Harley

    It's looking positive for these to go ahead.

    We only require around 5 more people who would like to commit.

    Retail will be 850euro per unit, a small discount will be offered for those who can confirm an assured purchase.

    Final decision will be made in 3 weeks then it would be 14 weeks delivery.

    Pm if you have any questions.

    Cheers,

    Harley

    Hi Harley, digressing slightly, I'd be interested in a bolt on GS EFI kit. There's a clip on YouTube with a guy called Eddie doing one car.

    This project is going ahead, drawings are being finalised.
    There will be a small run of GSA units as well as GSA lsd with 2cv output shafts ;-)

    Ps. There is no such thing as a bolt on EFI kit for any car, manifolds, fuel lines/returns, sensors, wiring all need adding/modifying. Megasquirt is a good place to start that worked for me.
    IMHO the besy place to start would be a tunable coil-on-plug ignition sysyem, that would give you the most bang for your buck efficiency, power, torque and reliability increase.

    Why would you need a limited slip diff in something as low powered as a GS?

    Gs engine is not low in power if used in something lighter, nor is high power output required to get benefits of an LSD like Quaife.
    I plan on putting it in something even lower in power, my 2cv, that is so it can aid me in doing this:

    Quiafe LSD will also improve everyday handling on road cars, particularly in corners, it would be a nice addition to your project Roger
    Many BMW powered 2cv's and kit cars run GS gearboxes, as do more and more 4x4 2cv's and Mehari's due to the greater torque loads.

    I was wondering that myself. You could barely spin a wheel in a much more powerful GS, even if you tried hard. the 2cv looks like it's doing better than fine i the utube clip below, with a quaife it probably would have bogged down and stalled.

    There's been poeple trying to do quaife diffs for CX's too ...... Why They have some of the most incredible traction of any factory 2wd vehicle I've ever driven. I can't imagine a time when a LSD would help.

    Thats an interesting comment, on that dune a few large 4x4 where bogging down because it was soft sand, my 2cv was unladen with a long run up, tyres at 6psi. Even then I would get wheel spin on stepper dunes and simply be unable to climb because of traction not lack of power.
    A locked diff would be ideal but an LSD is a huge step up from a free wheeling diff.
    Why would an LSD cause it to bog down in soft sand?

    I have a much cheaper solution for my GS. I just avoid sand dunes!

    I was thinking it wouldn't have anywhere near enough power to spin two wheels, so the motor would bog down and stall. One wheel.... it might spin if it was slippery enough I obviously wan't there though .........

    Yes engine bogging down on steep dunes is a problem.
    I only imagine these units being of interest to modified/specialist vehicles using GS type gearboxes, not for GS's themselves!
