I've asked this before but did not get an answer. I am no engineer
either. How big should the opening be on a ram air scoop feeding air to
the engine on an IO 540 at 2300 rpm's? I understand it is best to not
have the scoop any bigger than necessary because of the overflow forms a
slow mushroom of backed up air pushed ahead of the scoop. Any takers?
Mine is about 2.5 by 2.75" expanding into an airbox with a K& N filter
then into the 3 inch orifice under the engine.
