<DIV><FONT face=Arial size=2>It's Friday--going to Omaha--I was thinking about
what it was about the noise we liked: My Company is oriented to designing and
implementing Automotive Conveyor Systems(KC--Conveyortown USA) and most of
our union Millwrights and Ironworkers have Harleys(we also have the KC Plant's
maint. contract). These guys will go buy a new $20,000.00+ bike, ride it
directly to the mod shop and put on straight pipes. What'd ya do THAT
for? "So it sounds like a MOTORCYCLE!" Pattern ships
used to scream--it was what a pattern airplane was SUPPOSED to sound
like........but our ears used to ring for a few days following a contest then
also.........Have a great weekend and thanks again for all the
help.</FONT></DIV>

<DIV><FONT face=Arial size=2>We were looking for ANY way to quiet those
suckers down. My deal was running a RE short stroke Rossi in a
heavy, clean E-HUGE-1A and turning an 11-7.5 wood prop 18,000+ on the backside
of a Split-S. It was great. LOUD--but great. The pipes would
RING. Prop flutter was an issue along with airframe and pipe noise,
engine speed, etc., etc......... No question the newer stuff is more capable
and the patterns more challenging--but I don't know if they are more FUN.
<EM>Part</EM> of the enjoyment was going out and making some serious
racket.</FONT></DIV>

face=sans-serif size=2>I was under the impression that the real cause of
excessive noise was prop (rpm & diameter). The actual engine noise
and exhaust setup (by todays typical standard) was not the significant cause
of noise - the prop is the culprit. <BR>Jim

<BR><BR><FONT face=Arial size=2>Anyone,</FONT> <BR><FONT
face="Times New Roman" size=3> </FONT> <BR><FONT face=Arial size=2>When
we first started trying to quiet things down, one of the areas we looked at
was intake noise. We used to use a stretch on filter housing with
small filter disks that helped the noise problems with the added benefit of
keeping crap out of the engine--gee, what a concept. Are there any
such animals available now? We fly off an old asphalt runway and there
is the possibility something significant was sucked into a brand new 170 and
destroyed the piston, sleeve, ring and bearing. First time for
everything, I guess. The 60 sized ones did not seem to affect
performance.</FONT> <BR><FONT face="Times New Roman" size=3> </FONT>
