I can't think of a better way to do this other than a survey. I'm not looking for a debate. I'm no expert on the many varied engine variants of the IO-320 and I want to place my order for the finish kit next week. I'd like to use the SJ Cowl but between updraft, forward facing, sump position, prop extensions it's a bit cumbersome so I'd like to know what has actually worked in practice for others.
My 9a will have an IO-320 with a 3 blade Catto prop and I have no intentions of changing to constant speed.
I'll need a vacuum pad for a gear driven backup alternator (don't know if all engine variants have the vacuum pad).
So the questions whittle down to
Which specific IO-320 variant did you choose? D2A, D1A, other ?
Which Sam James Cowl? Shorty, extended updraft, forward facing?
Did you use the SJ plenum or VANS baffles ?
Greatly appreciate the input.
