ok, so i've been figuring my tuning on a 6" aero port...but i realized that since i'm gonna have two of them, its probably wrong, how would i find the tuning for this?

C= D x 3.14

C= 6 x 3.14

C = 19ish x 2 = 38 inches or circumference...

i'm lost on how i would tune this...

Circumference is the length of perimeter of the circle, not its area.

A=pi*r^2

Go there and use their calculator.

Total combined diameter.

SQRT(A^2+B^2)

SQRT(6^2+6^2)

SQRT(72)

8.4852813742385702928101323452582

Area.

Pi*R^2

3.142*4.242640687119285^2

56.55 (just round it to two past decimal)

So your port area using dual sixes would be 56.55 square inches. You can use math or just download WinISD Pro (http://www.linearteam.dk/default.aspx?download=winisdpro), which will yield you the same port area. Or as Immacomputer suggested just use PSP’s online calculator (http://www.psp-inc.com/psp-inc.com/cgi-bin/port_length_calculator.cgi).
