Jeremy1998 Posted December 23, 2010 Report Share Posted December 23, 2010 I found a nice port length calculator on the internet... I just want to double check to make sure that it calculated right. Box: 10^3ft. (10 cubic feet) Port: 160^2in. (160 square inches) Tuning: 28HZ Port Length: 40in. long (39.59416767123559) Quote Link to comment Share on other sites More sharing options...

Jeremy1998 Posted December 23, 2010 Author Report Share Posted December 23, 2010 I downloaded the calculator... And I want to smash my head in with a mallet. I don't have dimensions... Because I need to add in the size of the port to see just how to fit it in... Quote Link to comment Share on other sites More sharing options...
JaM Customs aka mprete Posted December 23, 2010 Report Share Posted December 23, 2010 them plug and play bro. make some dimensions up and keep making them longer and shorter and wider, eventually you will find a size that matched the tune (hz) you want to get. and thats your port size. or use a port calc, and plug it into the torres calc and see if they match, cuz thats all any of us will do is put all your info into that calculator. its impossible to just know hoe big your port should be off the top of our head lol pretty much anyone that will comment is using that calculator, if not most, then everyone Quote 2001 dodge ram 2500 quad cab 5.9L V8 my build logs... dodge build http://www.stevemeadedesigns.com/board/topic/94914-mpretes-2001-dodge-ram-2500-quad-cab-build-log/ trik build http://www.stevemeadedesigns.com/board/topic/94447-trik-build/page__p__1298547__hl__trik__fromsearch__1entry1298547 box building thread- very cool designs (PICS!!!) http://www.stevemeadedesigns.com/board/topic/95713-2d-or-3d-box-pics/page__gopid__1318152entry1318152 i am a mechanic, pm me if you have questions or anything.

Jeremy1998 Posted December 23, 2010 Author Report Share Posted December 23, 2010 I think I've got it... I set the Desired Net Volume to 10^3ft. and the port to 6 X 24. 40in. long gets me 27.88HZ., so I guess that's about right? Quote Link to comment Share on other sites More sharing options...
Jeremy1998 Posted December 23, 2010 Author Report Share Posted December 23, 2010 Oh my God! I just realized that a 10^3ft box with that port and sub displacement is damn near if not over 15 cubes! I can't possibly be right, can I? Quote Link to comment Share on other sites More sharing options...
Torres Posted December 23, 2010 Report Share Posted December 23, 2010 tricky thing with boxes (which is why i have desired net/gross volume boxes) is that if you have a set port surface area, then adding port length to the current box will decrease volume, which will increase the port area per foot, which will increase tuning. so to lower tuning, you add length, which increases port volume, decreasing box volume...etc lol. so i see what you mean. but as long as you know how it all interacts, it's basically what volume/tuning you want and what equipment you have. setting the desired net/gross volume maintains that volume regardless of dimensions. helps for tuning if you NEED a certain volume, that way you aren't constantly changing dimensions to get your set volume. and that is correct. with your port dimensions to get 160 sq inches, port volume is about 5 cubes just to get a tuning of just under 40 hz. with a net volume of 10 cubes. so a gross volume of 15 cubes is needed Quote Link to comment Share on other sites More sharing options...
