[QUOTE="1aespinoza, post: 8831546, member: 654802"] It is an important parameter. What this parameter means is the area of the port. It is the opening of the port in square inches. So the port can be 5x6, 2x15, 5.47x5.47, or a 6" port (3x3x3.14) which will equal 28.27 square inches. Now the Displacement 0.15 cubic feet, you multiply by 1728 (# of cubic inches in a cubic foot). It gives you 259.2 cubic inches. You divide that by 30 sq. in. and you get 8.64. So your port should be 8.64 inches long. For the round port it should be 9 inches long. [/QUOTE]
