I searched and didnt find anything. Is there by any chance a calculator out there to do dual aero ports? Ill most likely end up doing a slot port but read that aeros are more efficient. I got two 3" aeros that are about 12" long with flared ends and stuff, might want to use them sometime for something and no idea how to calculate how id use them if i ever needed to.

Bullshlt you search

But Ill help you anyway, and yes aeros are more efficient and better in pretty much every aspect other than cost

i use this cal. to give me meas for my setup. remember u measure the length from where its straight, where the port bends doesnt affect the sound.

Dont listen to what this idiot just said, bends do count in overall port length

If using flared aeroports, then just add 1" to the length that the calc gives you.

It does affect the port length, you have to take the length down the middle of the bend from what I heard. So you can take a string and hold it to the inside add the length of that and the length of a string held to the outside of the bend then divide by 2 to give you a length


If using flared aeroports, then just add 1" to the length that the calc gives you.

The PSP calculator shows your a length for straight vs flared.

:laugh:


so what WOT said in nicer words....

wilj24 that is inccorect information. A bend does add to port length, and next time try your hardest to supply factual information please :D but hey we all have to learn right?

Ya I heard you can use teflon braided nylon rope (has to be teflon) for your power wire to, mad flexibility with no voltage drop. On the cheapness to, son.

Cant wait to try it out
