... did you even READ what I wrote? "...this mod
increases effective combustion chamber volume by removing a section of spark plug thread,
thereby lowering efficiency by lowering the compression ratio..."
BTW, premium fuels do not "burn slower" as such - they are merely more resistant to spontaneous combustion due to elevated pressures/temperatures.
