Hi 

Turbulence was yes it was, but only to properly mix the fuel and air in the intake 
manifold with carb's or tbi's, since we are injecting the fuel close to the intake port 
we are looking for smooth passages to get the least amount of friction thus we have more 
cfm, now days to mix the fuel and air heads with swirl combustion chambers are used.
