| Subject: | Woodward vs McCauley Governor Height |
Does anybody know if the Woodward governor is shorter than the McCauley governor?
I've got a McCauley on my IO-390 and was doing the left front floor baffle
last night and with the cutout for the governor, there isn't enough room for
the big, square fiberglass intake hole between the governor and the left sidewall.
Its something like 1/4" to 1/2" too narrow and that *doesn't* take into
account any mounting flange space. I'm wondering if the Woodward governor is
shorter by a 1/2" or so which will make this all work. Basically, I don't see
how I'm going to get the McCauley to work at this point.
Anybody have any height specs on the Woodward governor? Basically from the boss
mount to the top of the arm would be helpful.
Thanks!

I am sorry I don't have a photo.
All that I did was take some left over 0.020 aluminum angle and cut it about 1.25"
long with an angle cut on one side.
I placed these at the aft end of the cowl (right before the exhaust) at about a
45 deg angle, about 1/2" apart at the leading edge of the vortex generators.
I only placed a total of 4 of these on the bottom of the cowl.
Looks like:
Aft end of cowl

I had a problem with higher oil temps back in 2002.
I installed vortex generators at the aft end of the cowl opening.
This did wonders for my oil temp. and have never had any problems since.

Tracy,
Have you seen the stuff on the CAFE web site?
http://cafefoundation.org/v2/main_home.php
Click the 'research' tab, then 'cafe reports', then 'local flow I, II, &
III.
II discusses louvers & 'bluff bodies'.

| Subject: | IO-360 Snorkel Induction Installation Plans... |
Dear Listers,
I must just be totally missing it, but I've gone through all of my prints twice
now and I cannot find anywhere where the installation of the Induction Snorkel
for the horizontal intake is described or even shown. I'm guessing its got
to be an "OP" drawing of some sort. I would also assume that there would be some
written instructions, but I'm not finding these either.
I'm just not sure what I'm looking for at this point. Can somebody help a brother
out...

Ah, can I get a "what, what!?"... All of the goodies were tucked inside of the
K&N filter box that comes with the FAB-HORIZ INDUCTION-1 kit including the plans,
instructions, and all the bits and pieces! Those Van's shipping people must
be squirrels... $205 for a replacement snorkel I just noticed in the Van's
catalog; guess I'd better do this right the first time...

Matt,
I think you are correct in assuming it is an OP drawing for the horizontal induction.
I don't recall ever seeing plans for anything except the vertical induction.
I suppose it is time to call Van's

| Subject: | CB-1002-H Governor Bracket Installation Photos...? |
Dear Listers,
Van's turned me on to a bracket for the RV-10 called the CB-1002-H which is a bracket
for mounting the governor control cable on front mounted governors.
Does anyone have some good pictures of how this bracket is installed? Maybe even
a scan of the baffling installation OP sheet where the RV-10 baffling is described?
Since the IO-390 has a front mounted governor similar to the IO-540 used on the
RV-10, some of these baffling pieces seem to work.
Any docs you could provide would be most appreciated!
