    GTD Restoration completed!

    Julian, you mentioned in your earlier posts that your exhaust noise was 99Db. How did you manage that?. I have a CAV GT40 with twin oval mufflers and failed miserably the noise test at Castle Coombe a while back. Is that a bespoke muffler or off the shelf product?.

    GTD40 Restoration

    Interesting discussion on the final drive ratio of the Renault transmission. I have a Renault un1-13 with 3.44 diff. I have recently installed a 3.89 final drive to keep my engine more on the "boil", as my engine's torque and power curve is higher up in the rev band. This experiment is purely...

    any cable shifter designs

    Use a Mazda MX5 shifter, the mounting plate may need some modifications. You can pick up these shifters on e-bay quite cheaply.

    UK Circuits noise regs - 98Dba @ 4500 rpm

    Julian, the only circuits where I can take my CAV GT40 are Silverstone and Rockingham where noise is less of an issue. I think the drive by and static noise limits are 102db and 105db respectively. Because I live in Bristol which is not very far from Castle Coombe, last year I thought that I...

    UN1 13 Grinding when trying to shift

    from my own experience you need more slave pin movement. I do not think 12mm is enough. You need to sleeve down the slave cylinder, which will give you more movement at the expense of harder clutch pedal. Speak to Frank Catt.

    CAV GT fuel gauge not working

    When left fuel tank is selected, the left fuel pump works but the fuel gauge shows zero, when I know the tank is almost full. However when the right side tank is selected the Gauge works fine. Any ideas? Should I look at the sender?.
