The balance tube is the tube connecting the 1 & 2 port to the 3 &4 ports.
Its area - the diameter of the tube - determines how much air can go back and forth.
You have to do some work to get these things right. Too many variables to just use a stock formula. You take your application and do a series of tests and see what works best. Control the conditions, do it on a dyno if possible, or time to distance, or G tech, etc. No easy way to get it right. Or use exactly the same setup as someone else who has done the testing and you will likely come close to his results.
I can't answer the question as to wether changing the intake length would be beneficial. Have never tried it and don't want to waste time doing this sort of testing on a stock engine where the performance gains will necessarily be very limited.
