Shaun,
I have done nothing in the way of intake mods to my Dak, but did several to the old small block Chevy in the mid 70's. And now with my qualifications strongly in question, your description of laminar flow is basically correct. I would think that a maximum mix of the air-fuel would be desirable. If this is the case laminar flow is not the effect we would want. As an example, if you have ever noticed the wind tunnel videos of laminar flow with smoke tracers the smoke does not 'mix' with the airflow until well past the transition from laminar to turbulent flow. I wish I had a video to post, when I find one I will provide the URL. For moving a lot of fluid with the least drag it is a good idea, to mix fluids together turbulence is the best flow mechanism.
Just my thoughts on the concept.
oh yea always remember "you can tell an engineer.... but you can't tell him much"

Subject: DML: Smooth air....
anyone has attempted to force Laminar Flow in their intake systems. For those
that don't know what Laminar Flow is, it's essentially like a laser beam. One
of the big differences between a laser and a regular light source is that the
light from the laser is all travelling the same direction at the same speed.
A regular light just tosses light all over the place.
In air, the molecules bounce all over the place (even if they are roughly
moving the same direction) and this is turbulence. Laminar Flow air means all
the molecules are moving the same direction at the same speed. When they
reach an obstacle they cleanly split around it (instead of bouncing back into
the air stream as turbulence) and if the obstacle is in the middle of the
stream and evenly shaped, the stream will re-join on the other side of it back
into a smooth flow. This sounds like exactly what we want to happen in the
Throttle Body of our intakes.
I was wondering if anyone had attempted to induce Laminar Flow to affect
preformance of the engine. If anyone else is curious about trying something
like this, it might be fun to put our heads together and see if we could come
up with a system and test it...
