well... go on... explain. don't just doubt and then not back it up with anything :P i'm open to suggestions with good reasoning. i haven't started TIG'ing yet

Spoken just like the engineers I work with or the local building engineers that weren't going to OK a planned system I was using because they had never seen it used and didn't like it. You may want to add a reason why you highly doubt, or at least define "work", but just throwing out a statement like that isn't very helpful or considerate ....chief.

well, i'm not stupid, i'm adding more tape than that... it's just a "Tack" piece. i'm not going to cheap out with the green tape though,

I'd like to think that because he has a degree that you guys are right, but I've decided that degrees are way overrated......after all thermometers have degrees and we all know where they stick them don't we? :P

Been waiting a long time to use that one around here, eh?!

ok, this is only slightly scientific. if you're gonna tell me... "that isn't based on real world, blah blah blah", save your breath, i just did this to get an idea of what's going on inside with the air. i figured it was better than absolutely no kind of testing at all.

tools used is a smoker for finding leaks in intakes, exhaust, and evap. systems.. works pretty good for those things, and IMO, kinda gives me a good idea of what's going on in here :)

low pressure

vacuum (through #5 port)
http://www.youtube.com/watch?v=E9P-e4uNlpY

it doesn't tell me how it equalizes the flow between cylinders, but it lets me know how the air is going through all the channels. it does have a noticeable tornado effect under the low pressure, but once the vacuum is one, POOF, it's all sucked in pretty smoothly. the smoke dispersed very evenly amongst the second plenum.

i dunno, it appears ok to me, but please pipe up if you have a worthwhile suggestion of notice... i'd like to start welding it up soon :D

i dunno know boss, it's hard to see what's really going on in there. Why don't you just button it up and have it flow benched?

You can always cut it open again after, and modify it.

ja, i was thinkin' that. if it doesn't work so well, i can cut the plenum off and make a standard plenum super easy.

i think i'll get to buttoning up on it :D

Derek, Issam may be correct, but you can really only tell if it is going to work with CFD. Flow benches are nice, but they cannot give the full picture (they can only say if you have balanced flow, and then don't even tell you what you need to do to fix it).

Have you gotten the urge to pick up some of the design books that are out there? They can be a little spendy, and can be a little math-y...

Have you looked through the thread and youtube vids that this picture belongs to? I have them bookmarked.

well.. huh. i don't think this alum. is sturdy enough for some heat :P i was really easy on it too!

You need more heat in the right places.

hey, there are actually a few of us that have engineering degrees that are not super cocky know-it-alls and realize there is a lot to be learned from people on the feild who are actually doing the work. 8)

the main curved piece i tried welding this to is 6061 T6, and i think these small pieces are T3 or something much softer. i know a little bit about what i'm trying to do, so i started with the heat on the thicker, harder piece and then moved over. i got a tack to hold it in place, then let it cool a bit and came back to give it a better hold in place and the small thin end fell off and hit the ground to go splat. haha.

i think i'll try cutting some thicker pieces out of the T6 sheet i have and give that a whirl. i may end up with less diverters though since they take up some of the space in the slot. or i'll revise my design again to make it work.

Using one type of aluminum would probably help a lot.

Seeing as how you like melting stuff :P you might want to try your own casting.
