Scoop-Making

[Bob Pastorello]

Decided I want to use a scoop on my latest for crankcase/bearing cooling.  I know where to locate it on the cowl, but have no idea of shape, angle, if any "ducting" is needed.  It looks like the scoops out there just direct air based on their shape alone...without ducting.
    Anyone have any suggestions/ideas on this?
    What to make the scoop out of?
    And how to determine what size is "right" ?

Any insights much appreciated....thanks in advance.
