scratchy Posted March 28, 2007 Report Share Posted March 28, 2007 Remember, a port is only a "source" of friction for the escaping air. that being said, the only differences is really smoothness of the port and calculation errors. I can go into detail about why I say they are exactly the same Quote then im rambo bitch Link to comment Share on other sites More sharing options...
Slinky Posted March 28, 2007 Report Share Posted March 28, 2007 well put! i knew it wouldnt make any diff but i didnt know how to word it like you did.

scratchy Posted March 28, 2007 Report Share Posted March 28, 2007 thanx, i researched ports and how they work for 2 years, so I can write a pretty indepth article about it. lol Quote then im rambo bitch Link to comment Share on other sites More sharing options...
Slinky Posted March 28, 2007 Report Share Posted March 28, 2007 Nice! i know who to come to if i have a port question. (although i shouldnt) lol.

scratchy Posted March 28, 2007 Report Share Posted March 28, 2007 haha, man, the physics behind a port is real easy. The longer the area air has to travel through, the more friction. More friction causes air to move slower. Slower air equals less "cycles" per second = lower tuning frequency. the diameter of the port though is a really touchy subject and I'm still trying to figure out how to use that properly in my spl builds Quote then im rambo bitch Link to comment Share on other sites More sharing options...
Slinky Posted March 28, 2007 Report Share Posted March 28, 2007 ive never heard it been put like that with the friction and all but it makes sense.

scratchy Posted March 28, 2007 Report Share Posted March 28, 2007 thats why varying lengths have different tuning frequencies. frequency is basically the speed of the air(in a sense) making the air slower decreases the frequency. How do you make the air travel slower? Quote then im rambo bitch Link to comment Share on other sites More sharing options...
Slinky Posted March 28, 2007 Report Share Posted March 28, 2007 longer port Quote DD M4 Rockford Fosgate P500-4 SoundQubed HDC415 w carbon fiber cap 2 Rockford Fosagate T1675-S XS Power D3400 Under Hood XS Power D5100 in rear Michael Singer 200A Alt Build Log: http://www.stevemeadedesigns.com/board/topic/153901-2012-veloster-update-842013-wall-build-4-15s/ Link to comment Share on other sites More sharing options...
scratchy Posted March 28, 2007 Report Share Posted March 28, 2007 yes....more friction Quote then im rambo bitch Link to comment Share on other sites More sharing options...
Slinky Posted March 28, 2007 Report Share Posted March 28, 2007 so lets get on port area a little bit Quote DD M4 Rockford Fosgate P500-4 SoundQubed HDC415 w carbon fiber cap 2 Rockford Fosagate T1675-S XS Power D3400 Under Hood XS Power D5100 in rear Michael Singer 200A Alt Build Log: http://www.stevemeadedesigns.com/board/topic/153901-2012-veloster-update-842013-wall-build-4-15s/ Link to comment Share on other sites More sharing options...
