Hello All,
I'm building a 7A with a 200hp IO360-A1A which has the horizontal induction. This also means I'll be using the snorkel. I've got the rear and side engine baffles just about right. I've got a large oil cooler mounted to my firewall and SCAT hoses and cooler hoses installed. That' s the part I have more or less understood what I was doing. Now I have started on the nose pieces (Inlet Floors) but I don't really understand the fit/dimensions I am going for up in the cowling nostrils, nor for the snorkel or the overall fit in the cowling.
Should the baffles on the nostril floors be cut back about 3/8" and even with the lower nostril fiberglass floors? Also on the vertical sides of the nostrils, how far forward should the side baffles ride into the side of the nostril? How does the rubber baffle material ride in this horizontal nose area? ie riveted to cowling and overlapping the inlet floors? How much overlap, etc. Just when I'm nearing completion and feeling more like an expert the baffles come along and now I'm back to a baffled novice.
Any good pics to refer me to? The instructions and drawings are not extremely clear to me of the best fit in the nose of the cowling once things are all put together. I just want to get this together cause I'm ready to start her up!
Much Thanks!
