NACA vents for engine air supply ?
I have an RV4 with SJ cowl and FI 0360. I have fabricated a custom fab and also fitted an AFP elbow with conical filter. Both are not great aesthetically to modify the cowl for clearance.
So, a rear facing servo fed by NACA scoops might be an option. They would supply two air sources with enough air for an 0360 and address the alternate air issue. What does history say about this air supply config ?
