Tony,
I did something like you are proposing on my Cozy. It worked - but
performance wasn't the best. Primarily for 2 reasons: 1) too short; and, 2)
sharp edges at the intake opening. After 50 hours of flying with the original setup (like yours), I made two
independent tubes from fiberglass that mated with the intake opening then
extended them forward about 12" and terminated them in the air filter box
with a generous bell mouth and rounded edges. The air filter box was
attached to an armpit scoop.
Pic Intake5a.jpg was the original intake.
Pic Intake-New1.jpg is the new intake.
Performance was much better with this mod. Performance also increased dramatically when I modified the exhaust to a
tuned exhaust instead of the "Tangential-Can" type manifold (too much back
pressure).
Hope that helps.

Subject: [FlyRotary] Can anyone tell me if this will work
what I'm trying to do is figure out how to set up my racing beat intake
without the intake tubes going over the top. the (bearded one) says it
will work but is only for engines in the 10,000 RPM range and it's not
good for 6500 -7000. does anyone. have any other suggestions. I will use
four injectors but what I want to do is keep the profile as low as
possible.
BTW this is for a Long Ez I'm thinking forced air injection
Tony
