Hi All,
This is on a 7A with a forward facing sump (IO-360-M1B) and an AFP FM-200
servo.
I'm at the phase of needing to connect the filtered air box to the AFP servo
via the VA-132-1 snorkel. I've done some searches and found some links to
folks that either 1) go the route of RAM air (ie. Robbie Attaway), 2) or
essentially cut off the end of the snorkel and reglass the portion that
connects to the AFP servo, or 3) somewhere in between. I've also looked at Rod
Bower's setup but it's a little out of my price range.
I am toying around with the idea of doing away with the lower half of the
snorkel and then using some 3.25" ID SCEET (1) tubing. My concerns with using
SCEET is that it is not recommended for negative pressure applications and I
can't find any data on preassure loses (especially around sharp bends).
Are there are any other options available? If you've got pictures or know of some links, I'd sure like to see/read them.
Notes:
1) SCEET: Aircraft Ducting "SCEET" type ducting has two plies of silicone
rubber impregnated fiberglass similar to SCAT except wire between plies. Sold
by the foot.
Features: Highly flexible and can be easily installed around obstructions and
sharp bends. Has less friction loss than similar non-lined ducting.
Applications: Ideal for use in conducting extremely cold or hot air at
temperatures ranging from -80?F to +550?F, and for conveying fumes. Not
recommended for applications involving liquids or highly abrasive materials, or
for negative pressure applications.
Thanks,
