pabs should be qualifying in the top 10 on the grid
As to why this affects effiency, well think about it this way:
Turbulent flow is in general very messy right? This means there are swirls and eddies and what have you present in the flow. So imagine this, your No. 1 cylinder happens to get its air from a region of the flow that had high concentrations of fluid while your No. 2 cylinder gets it from a region of the flow that was very thin. Your fuel-to-air ratio in each case will be different and will have different power outputs. Neither case will be optimal and your overall efficiency will be lower. As a general rule, you always want laminar, "clean" flow. I can show you some instances in aerodynamics where turbulent flow is preferred, but they are rather few and do not apply to what we are talking about. As always, these are just my general comments, based on what I have learned and studied. I am not an expert in combustion so if anyone has a different idea, I always enjoy learning from those who do know what they are talking about.
