My 320 is a couple months from flying and I am in the process of finishing the
top of the cowl. The cooling arrangement I have chosen for my stock IO-320-
D1B (160hp) is as follows:
o Standard factory baffling
o Large NACA duct on the right side of cowl for oil cooler
o "Shark gill" exit for oil cooler air on left side of cowl
o No "ramps" inside cooling air inlets
o Blast tubes for mags and fuel pump, taking air from rear baffle
Dan,
If the "shark gill" is buried, it is useless. If it is raised (as those purchased from Lancair), it is OK.
What about the blast tube for your vacuum pump? What about one for your alternator? Switch the one from the magd to the vacuum pump (unless you are all electric).
Finally, if ;you can, build the plenum.
