6" Precision Port vs Slot port ( single 15")

[thehardknoxlife 10+ year member]

A 6" aero = about 27". I believe a single larger port is more desirable than several small ones also. I've used two 4" aeros on a 15 before with no noise so I think the one 6" is fine.

Ah yes. A error by me. Fixed.

go with a slot port, aero ports are notorious for port noise. When i did a modeling with one 6" port you will still get a slight turbelance. Go with a slot or 2 4"

2 4" round ports have less cross sectin than a single 6" .......just for clarification purposes since alot of you have seem to figured it out already

2*2*3.14=12.56

12.56*2=25.12sq in

3*3*3.14=28.26sq in.

WE get dumber and dumber new members every day.U need more port area that 1 6" areo can offer.If u do a slot port remember keep the 3:1 ratio.Port width and length for no port noise.

I talkin about the other people in the thread give very stupid/uneducated informantion.

a single 6" could "work", but it be about .21" too short.

you need 15.21" from end to end of port. it says to substract 5" from Lv you end up with 10.21"

i believe the center pieces on those ports are only 10". so you could get some pvc pipe and make your own center piece.
