[QUOTE="IDSkoT, post: 5448699, member: 584344"] The point of those 45* angle turns is to prevent violent air. So it's a smooth transition. Having something that goes =o= isn't conducive for proper flow. Basically. Port = Opening Diameter AT ALL TIMES (is what we aim to achieve). People leave it with the 90* angle because it's easier... but for proper air flow, so you don't create a sort of vaccuum effect, you want to try to keep the port diameter equal at ANY given cross-section Not to mention, the dimensions you're measuring at are impossible to do with out a CNC machine. If you want, PM me with a link to the sketchup file and I can fix it for you and add notes, if you'd like. EDIT:: Also, interesting design. Putting amps under it? Seems like a good place to but some Batcaps [IMG]//content.invisioncic.com/y282845/emoticons/naughty.gif.94359f346c0f1259df8038d60b41863e.gif[/IMG] [/QUOTE]
