quick winISD question

[RKPsk8er 10+ year member]

winISD says that with 3 cubes @ 34hz needs a 6" aeroport needs to be 16.78" including flanged in correction.

I then checked for two 4" aeros with 3 cubes @ 34hz and it says 16.05" including correction for flanged ends. My question is if this means each of the 4" ports needs to be 16.05" or if it means that I need 16.05" of total port length.

Thanks!

i made a thread on this a few days ago, the answers i got were that each port needs to be the length that win isd specifies, so each port would be 16.xxx long

Since when does WinISD do flared port calculations? Flanged and flared are not remotely the same thing.

You want to select "two free ends"

Shut up, you're wrong. It's 16 a piece as SPY said.

I found some information relative to the question. I had posted this on another forum some time ago when the discussion came up:

Scroll down about a third of the page: Effective Length

I didn't read all of that, but if you read the instructions that come with PSP aeros they say the overall length of the port (with both flair ends installed) needs to be 1" longer than your desired port length.

It looks like that link just describes why.

WTF is your problem? You're wrong, act like a man and deal with it instead of grousing like a little girl.

Just WTF is your problem??? You have some wild hair up your azz about not wanting to learn something or that you rather just be an ignorant fool telling people you think you actually what your talking about?
