Where are you going to find 8" bends?

and your taking the OD of the pipe into account for displacement right, not the 8" ID

Could you help me with getting three or four 6 and get the tuning around 33 and 48?

the ed area of 3 6'' ports is ~105 which if they were around 30'' long they would take up ~1.8 cubes so doing 3 6 is going to be tough.

I didn't read through the entirety of each post, but my quick input on round ports:

PSP flared aero ports are my favorite. With a 15" in + or - 4 cubes a single 6 could suffice. Though, 3 4's could also be investigated.

As far as changing tuning for comps, you could have a different 6" or 4"s that you simply substitute in. Sure, drilling, re-drilling isn't great for the box, but that's what bolts and nuts are for, right? //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

After talking with some people about how much power I am putting at this thing, they highly recommend not going above 4 cubic feet.Some other people also commented saying that if I can stick with 3.75 cubic feet, 6" diameter pipes at about 13.5 inches long will do, they will be on the small side but I should be ok. Also a 3.75 cubic feet box isnt the best for spl, so I am just debating if its even worth it.

My question is, how do I plug one aeroport if I get those to help me get a little more port area?
