    Raising Compression Ratio

    Thinking about raising the compression from the standard 9:1 to 9.5:1. I am not looking for massive power from this car, I just want something that is economical and comfortable to drive. My understanding of raising the compression will:

    1. Increase fuel economy.
    2. Better performance on and off boost
    3. Increase throttle response.
    4. Cost less than going Hybrid.

    Only downfall might be higher combustion temps, but with a good intercooler and tuning this should not be a problem.
    Has anyone else considered doing or have done this before. What are your thoughts.
    Dave.

    i would have thought, i dont know, just thinking, that your power will still be limited by the standard ko4, therefore only real benefit would prob be a bit more torque? something standard rods dont like.
    seems to me a lot of hassle, for not much gain.
