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 PSPís online calculator (http://www.psp-inc.com/psp-inc.com/cgi-bin/port_length_calculator.cgi).
