[QUOTE="Jeffdachef, post: 8514489, member: 650438"] Its not just me thinking that its more efficient, its a fact that square-ish ports are more efficient than slot. What makes a port more efficient? Why are aeroport and square ports more efficient than slot? Easy its because you have a lot less surface area which which air makes contact with which translate to less friction and minimize turbulence. formula for surface area for a rectangular prism is A=2(WL+HL+HW) For example your port is a slot port thats 30 inches wide, 4 inches high and length is 20 inches, which is around 120 sq inches of port area this is the calculation for surface area Surface Area = 2×(20×30 + 20×4 + 30×4) = 1600 feet^2 Now with 120 sq inches of port area in mind, lets try different numbers and making it more closer to a true square. Height 10, width 12 with the same length of 20. Surface Area = 2×(20×12 + 20×10 + 12×10) = 1120 feet^2 Same the same 120 sq inches of port but much more efficient due to less surface area. now combine efficiency with how easy it is to make an adjustable/removable port for these type of ports, its a no brainer.
