this however seems to be a great design....and could easily work without moving headlights out of the way:
The basic shape of the plenum is the same, only with a 45* downward tapering inlet.
This seems to allow the velocity to stay high all the way to #4 and the airflow curls into the runners. If you look at the stock 1.6L manifold, it kinda does the same thing. The time between when #1 and #4 get airflow is much closer than any other design I've simulated.

Word. I think glass-filled ABS, either FDM or SLS formed, is used pretty commonly for test manifolds. Being a mostly dry-flow manifold helps too. ATI in Austin could do it easily, though they are not cheap. I would guess $3-$5K. The size makes it expensive. I do know a guy who has a rapid prototype source in China that is really cheap.
Here is an example:

The walls look a bit thin for a working prototype for this one. I think it may just be a test fit for an aluminum casting.

I need to get my escort cylinder head reassembled, at least on the intake side to build a ghetto flow bench. I've been wanting to try and build and test something like this for since my 2.3 Turbo days. Just never had half the equipment needed for this until now.

AbsurdflowTim @ BEGI
Turbotim. Unless, of course, BEGI hires me, in which case there'd be two Tim's at BEGI 
The only intake mani I've welded is the one on my car, and I wouldn't consider it absurdflow. It gets the job done (I/C piping thru the fender) which is more important IMHO.
BUT...I just got the whole sha-bang cosmos package loaded onto my home computer during lunch! Apparently we had an extra seat here at work
We're still running solidworks '07 so I'm going to have to start over with the models cause I can't import scott's '08 files, and I have never used Floworks so I'll have to teach myself that one. And my vintage '96 15" CRT will need upgrading, I'm used to running dual 19" LCD's at work hehe

Huh? This is BEGI's thread. BEGI Absurdflow

You mentioned your Rapid Prototype on the cylinder head and I think ZX-Tex said he wanted to see.. Was curious what kind of psychotic crazy high flowing contraption you might've come up with for intake side

Ill post up some pics here shortly but we are working on some 1.6L short runner manifolds and will be done with the first batch shortly. Orders can be placed via Welcome to Flipside

That design flowed the worst of every design brainiac tested.
