By porting the lower intake it now has the same rectangular shape as the heads, thus eliminating any flow restriction between the intake and heads. The benefit is less back pressure on the discharge side of the supercharger which allows it to produce the same volume of air to the cylinder with less boost and at a lower temperature.
