I am in the process of making an all metal plenum for an O-360 on an RV-7. I am using Vans baffle kit as a starting point. I have a few questions that are all over the map so please bear with me.
1) The baffle kit directions state .5? as the baffle to cowl distance. Is .5? really sufficient for the side baffles to upper cowl distance (along the rocker boxes)? I don?t want the plenum smashing into the top of the cowl.
2) Is a close fitting plenum top generally more efficient than a roomy one? Is there a magic engine/plenum distance that provides the best cooling?
3) Can I assume the fiberglass inlet ramps provided in the finish kit are non-structural?
Thanks.
