How much port area should I have for a Hertz HX 300 D? It's gonna be a normal slot port, not aeros. On the hertz site if give suggestions for an aero and it says this Ø= AR 80V. I have no idea what that means though. Will 24 sq inches be enough? I can't really get my design to work out well if i make it any bigger than that.
