| Since the shorter plug puts the spark at the top of the combustion chamber, the propogation of the flame front in the chamber can only go downward. This reduces the amount of energy lost to heating the parts of the chamber and keeps it within the gases to promote pressure, which means more power. And lastly, the polishing of the chamber makes the material more 'reflective', not only to the visible light our eyes can see, but also to other frequencies of energy, namely heat. Keeping the heat in the gas and away from the solid parts of the engine means better efficiency. Pretty bold claims. Where's the test data? I remember seeing Nissan doing combustion simulations when they designed the VG30DE. I'm sure they also built prototypes to see how they performed in the real world. Now you're claiming that in your garage you're doing something that they couldn't do with the equipment at their disposal. If it was that simple, why didn't they do it? Their engineers spent many hours performing tests, analyzing results, etc. to find the design that worked best. If they designed things a certain way when a cheap and easy fix would provide a performance improvement, they would have done it. Here is something that I've learned: If an expert does something that seems to defy your common sense, you're overlooking something.
