Sounds like too much restriction when you're going down the highway...Never have seen a shroud with flaps, but I have put louvers in a few to let the air go through the radiator easier. Air will always follow the path of least resistance, it it's easier to go around the radiator then thru it, that's where it will go..... When space limitations come in, hard to put the cooling system in the perfect configuration!
