IGV's ?
In a past life I worked on jet turbine engines. The compressor as well as the high pressure turbine used IGV's or Inlet Guide Vanes to increase efficiency of the turbine. I wonder why someone hasn't come up with a set of stationary vanes placed in front of the turbo inlet. Sounds like a perfect spot in place of the silencer ring. It would just direct the air flow into the blades. Of course, it would probably sound like a J-79 at take off power. GOSH! Did I just give away a multi million dollar idea?

Re:IGV's ?
I myself am wondering if that is a secondary, or maybe primary purpose of the silencer ring.
Ya, sure, mine has gone missing as have most here.
Part of me doesn't think it is only to reduce noise though.
Saw a post somewhere, maybe here, maybe there,
someone had what looked like a small stainless steel bowl that fit into the turbo perfectly, and had removed the bottom of the bowl.
This resulted in a nice flowing surface right into the guts of the turbo.
Can't remember if he claimed any benefits of this or not though.

Could be, Phox, but after travelling around that accordian bend in the rubber turbo-inlet hose -- that's got to be fairly turbulent air no matter what's done by the SR. Wonder if there's any benefit to straightening out the hose *and* building a "focusing cone" with stationary vanes?
Gee, more science!

I realize this unit is a bit off topic of vaned inlets but it might stir up some interesting ideas. I have no personal experience with this thing but it sure does look cool. I like machined aluminum stuff.<br><br><br>Nixter

Re:IGV's ?
I had one built a couple of years ago that actually started the air rotating before it entered the turbine. I ran it up unti, the time that I got my HX-40. it actually made the turbo noise less not more.<br><br>phox_mulder, If you are still running a HX/HY-35 You would be more than welcome to barrow it and see what you think... It just sits in my office at School.(DATC)<br><br>
