should also note. it is a fiberglass spare tire enclosure. my only venting option is a round port, probably with an elbow. im not a fan of pvc ports at all but the way my box is built its my only option.

Use the round port length calculator here.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
