    The "old octane question"(s)...sorry guys

    Does the octane rating effect the temperature within the the combustion chamber (given the same c/r) and how much? Does higher octane fuel burn "slower" than low octane fuel? All things being equal as far as tune goes are there ever any measurable power gains to be had by different octane...

    Effect of gearing on dyno figures.

    I was just wondering how changing the rear axle gear ratio would effect dyno numbers-hp and torque if it would at all? Thanks in advance for your "answers".

    Higher Compression motors and spark plug needs.

    Back to raising the compression ratio thing again..lol Is there a "stock" guideline one would adhear to when raising the compression ratio (8.5:1 to 10.5:1) in regard to heat range and electrode gap? Thanks again!

    Engine Compression vs. Exhaust Gas Temp?

    Given the same motor, same fuel (high enough octane to be compatible with the higher C/R) and different compression ratios (let's say one is 8.5:1 and the other is 10.5:1). Will there be any difference in exhaust gas temperature? FYI- I just "found" this site, after reading about 10 pages of...
