Looking at the airflow path *into* the stock cowl, it looks like the flow is much easier on the left (#2 & #4) side, as the #2 cylinder is stepped back, vs. the #1 side. On the #1 side the baffle ramp promptly hits the #1 cylinder and deflector plate, and the clearance is quite tight between the #1 cylinder and the cowl.
Has anyone played with making a modified ramp so that the air doesn't come in and then hit the wall of the #1 cylinder deflector nearly head-on? Seems like that would improve flow.
Here's a link to a pic of the area I'm talking about (although you don't realize how restrictive it is without the top cowl) https://images.app.goo.gl/gbGJEw43qbKMvh3h6
Maybe a cone shape in front of the #1 deflector?
