    Question about ports

    recently, i saw a pic on these forums with a port that went like this:


    And i was wondering, if you were to calculate to tune the port, would you have to measure the whole thing to calculate it? or just from the top to where it corners off?

    Re: Question about ports

    you measure the middle of the port, all the way through, and don't forget about the slot-port, end-correction thing
