Prechamber Mod "Flame" Front
Prechamber Mod "Flame" Front
My point is that if you are having to run increased timing that you are slowing down the flame front. The fact that you are increasing timing means that you are taking longer to reach peak cylinder pressure. So I do not see how the mod is doing what you want, assuming you want more power. If your flame front was faster from the larger holes then you should decrease timing.
I had assumed that the larger holes were allowing a larger amount of fuel to burn at a quicker rate. Because the holes were to small and causing a restriction for the volume.
