    Not sure about an AK but I and others fitted a remote servo (MGB) on my original Dax. It worked well. The only issue I had was insufficient vacuum in heavy traffic due to my quite radical cam. I fitted a vacuum reservoir too which helped.
    People will tell you that you loose pedal feel by fitting a clutch servo, which is true but I found it perfectly OK and you get used to it quickly.

    Hi Kev
    Just resurrecting this old thread.
    I am going to fit a remote clutch servo as my clutch is very heavy and due to my knee not being to good it is a struggle in heavy traffic.
    I note you used a remote MGB servo, I was just wondering what ratio it was as I can see on the internet that there a few variations 1.65, 1.9, 2.3. Correct me if I am wrong but the higher the ratio the easier the pedal should be.
    I note you mentioned the insufficient vacuum in heavy traffic, but did you have any other issues?
    I am running a Rover 4.6l V8 with an LT77 gearbox and a competition clutch.
    Any advice would be much appreciated.
    Kind regards
    Rob

    Hi Rob, yes the higher the ratio the lesser pedal effort.
    If you have enough engine vacuum you'll be fine.
    It depends what cam you have.
    I ended up fitting a vacuum reservoir which helped.
    You will find a tiny bit of lag but not a problem you get used to it.

    Hi Kev

    Thanks. I have an MC1 cam.

    I will probably go with the 1.9 ratio.

    Measure your idle vacuum which should be around 12-15 ins/hg and you will be fine in traffic. Some high lift cams only give you about 5 ins/hg which is where you will have issues.
