MAF SWIRL REDUCTION

[jac at wavecom.net]

I have used the material from a MAF device in an aircraft installation.  I believe there was some improvment in charge distribution.  Certainly there is a performance penalty consideration.  If memory serves me, there was about .4"Hg reduction in maximum WOT MAP after installation.  These measurements were made within an hour or so of each other.  This was a very subjective measurement, The engine may have been turning faster the second time.

You might consider a concept illustrated in the MACHINE DESIGN that came a few days ago.  A company markets a device that installs upstream from a flow meter.  They claim to be able to straighten flow within a couple of diameters of a 90 degree bend.  It consists of tabs angling down stream from the tube wall out into the flow at what appears to be a 45 degree angle.  The illustration shows four rows of tabs.  It looks like an idea that could be adapted to an induction system,

Gentlemen,

I am looking for some honeycomb type material, or similar device,
to begin investigation into swirl reduction in a supercharged blow 
through MAF situation.

Does anyone know of where I might find resources for this meterial
or device(s)?

Thank you,

Matt
