make an adjustable port, so that you can have it tuned low for everyday driving, and tune higher for the comps

"Conclusive" aka Chad Hines had some in his CRRX last season. He was running 2 TREO's in a wall. Monster port...he built a piece of wood with PVC pipes on it and scrweed it over the mouth of the port. Worked VERY well in his car.
His email is Hines156@aol.com. He's a sherriff and works odd hours, so be patient with him...hehehe

OK - I figured out the answer to my last question - but now - How little port area can you run with and not hurt the subs - I have two shocker extreme 12s (will also ask on SAF).
My SPL port will have 47.2sq but to get to 35Hz I will only have 27sq of port if I keep the same length (and just narrow the port to get SQ results). I think there is a ratio I need to keep (1 to 9 width to height), is that correct?
