Think it is very effective if you install =C2=A0= it for a side mount radiator

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