Here you can see we’ve added angled ducts to the sides of my NACA runners. I hope to do two things here, well, maybe three. I don’t want to suck rain (1) into the engine, so I was moving to the side discharge. I would also like to get better ram air flow (2) into the motor, so by taking a more direct route to the new air cleaner, and expanding the duct closer to the NACA (3), I think overall flow will be much improved. We’ll probably never really be able to tell if any of that is true, but I like it better.
