Plenum Questions:
RV-8 with a non-James cowling that has
round 5 1/4 openings. I'm making my own plenum for my IO-540
(currently I have standard baffles). I have the form for the plenum
nearly done and would like to use carbon fiber and high temp
resin/vacuum bagging for the plenum. I want to redo my engine air
intake (currently a K&N filter below the baffle plate in front of
cylinder #2. My questions and/or refer me to the archives:
1. Any recommendations for the high temp resin?
2. Source for the carbon fiber and types of carbon fiber to use?
3. 5 1/4" metal inserts that sandwich between the upper and lower cowling
halves-- machining from tubing? Tubing source so I don't have to start with a
solid block of aluminum?
4.The 5 1/4 metal inserts can be held in place by the rubber sleeves
(anchored to the plenum) and cowl opening only? No other fasteners?
5. Material for the rubber sleeves from the metal inserts to the
plenum? (I've thought I'd use baffling rubber fabric--my plenum
does not have round front attachment points.)
6. How to fasten the plenum to the metal baffles? Nutplates?
Reinforce the fiberglass edge with .040 aluminum on both sides of
the plenum attachment edge? Silicone rubber gasket between the
plenum and the metal baffle plates?
7. Anyone ever stolen plenum air from the metal 5 1/4 inserts by Y-
ing off from the inserts for a source of ram air for induction air
(not just a filter box below the baffle plate in front of cylinder
#2)? I'm considering modifying BOTH 5 1/4 metal inserts,
horizontally bisecting, i.e., TIG welding a horizontal plate(s), (or
probably using only 30% of the frontal area for induction air, rest
for cooling) in both of their openings. Separate rubber sleeves
would carry air to the plenum and engine air intake tubes on BOTH
sides. Intake tubes with individual(?) K&N filters could be
bypassed for unfiltered ram air with a baffle plate (controlled from
the cockpit), then to a "Y", then to engine intake.

Dear Listers,
This evening I will be upgrading the Matronics Web Server hardware to a new Quad-processor
2.8Ghz Xeon system (yes, 4-physical CPUs!) with an Ultra 320 SCSI
Raid 5 disk system and 5GB of DDR2 RAM.
As with the older system, the new system will be running the latest version of
Redhat Linux. Most of the software configuration work is already done for the
migration, but I still have to sync all of the archive and forum data from the
old system to the new system. I am anticipating about 2 to 3 hours of downtime
for me to fully make the transition, although it could be considerable less
if everything goes according to plan.
The Matronics Webserver will be *UNavailable* from the Internet during the work,
and you will receive a time-out if you try to connect during the upgrade.
Email List Distribution will be *available* during the upgrade of the Web Server,
and List message distribution will function as normal.
This represents a significant performance upgrade for the Matronics Web Server
and you should notice nicely improved searching and surfing performance following
the upgrade!
Best regards,
Matt Dralle
