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.
