Yes, the side louvers did indeed help with cooling my rotary Rv-6A. While there was a large opening on the bottom back of the cowl, the hot air near the top of the cowl had no easy exit before I added the side louvers. Plus they added a little pizza to the cowl

Here is a link to the old contact magazine on old installations.
You will see the side louvers on Ed Anderson RV6A
Maybe he has still photos of the side louvers in his engine cowl.
Think it is very effective if you install it for a side mount radiator

Le Roux, I have talked with Alex a bunch over exit louvers on the side. We are hoping to tune the exhaust dumping better to help pull air out of the bottom of the cowl. I don't see too many exit louvers though on planes. Any reason for it?
