  1. What is amazing is how quickly they have rolled it out, in May Jim was saying the RBRR would be long gone before they even got going. 

    It is in, and being enforced already.

    Think speed (ironically) is the way to go now with contentious legislation.

    Just remember, if you can see a street light, on or off, assume it is 20, as there is no requirement to sign the new limit.

    So many believe this!     There is no more energy in 100 octane fuel than in fuels of lesser octane rating.   The octane number ONLY refers to its resistance to knock, pre-ignition.    This does mean that you can run much higher compression which will generate more power, and modern engines that have engine management and knock sensors to adjust ignition automatically will produce less power with low octane fuel, but those are due to engine tune and timing, not the 'power' of the petrol!

    This was in an early PI car with timing tweaked to most advantageous and a TR4 with higher compression than usual and again tweaked ignition.

    Cars even sounded different to normal.

    Guess they were just making better use of the energy within the fuel, especially as both were designed for 5-star.

     

  3. My PI ran OK on 95, but preferred 98.

    My TR hates 95. 

    You can Aral in Germany that is over 100, (101 or 104 I think) and like rocket fuel. 

    The Shell Vpower is also higher RON in Germany than the UK version.

    In France the 98 has been fine for my PI cars, usually E5 same as UK.

  4. What car?

    generally could be a different clutch manufacturer, or mismatched parts, or pressure plate worn out, assuming you are comparing like for like cars.

    If you have a TR and are comparing it to a Spitfire, then yes, a TR is a hairy-chested sports car and has to have a proper heavy mans clutch. 🙂

  5. BP5ES better for PI cars, hotter plug, seem to be harder to foul, well in my experience.

    Even better are the Bosch 3 pronged ones, I have really struggled to foul them in my PI cars.

    W7DTC I think they are
