[QUOTE="Martyn Goodwin, post: 51735, member: 2433"] It seems to be a common requirement and is also stated as a requirement by PEI in "Tuning For Speed". I am sure Max can provide a incisive and correct reply. For me, logic suggests as the air/fuel mixture becomes more and more compresses (by increased compression ratio) the force produced by its explosive burning must also increase and as we are dealing with a fixed volume of charge, it implies that the burn rate is faster. If I am correct then we need to reduce the advance as we increase compression ratio to ensure we get the energy of combustion happening at the best time to provide optimum power. M [/QUOTE]
