Has anyone done any real before an after, documented testing, to see if this 'L mod', drilling holes actually works?

People remove the 'snorkle' which has rounded edges to smooth flow the air passing through to a hole with sharp edges and which is not aerodynamically efficient?

Another of the tribal knowledge gotta haves?
