They are a nice piece of work which should work very well. Anybody else considering additional exit opening area, I recommend them as a good find. I just waxed them up and tomorrow I'll make a mould off of it (sshhh, don't tell Lancair) as I'd like to make a spare one to experiment making a sliding damper on the inside, very similar to the ones found on the air inlet vents on the hood of my snowmobile. These are typically kept closed when riding in fine, dry, powder snow, then opened for riding in heavier, wet snow. But I can envision the same idea on the these louvers, operated as cowl flaps. But just in case I'd rather make a copy to try it on. Thanks for the good tip. S.
