The size and shape of the plenum chamber. After looking at = the=20 Mistral site (VERY NICE) I now have reservations about the size and = shape=20 of plenum I was going to use. Originally I was going to manufacture one, = box=20 shape and only 2 1/2" wide 3 1/2" high 8" long. Really didn't think it = would be=20 big enough but made for a neat installation. Now im considering = extending the=20 inlet runners completely over the engine and mount a tubular plenum = approx 4"=20 dia 10" long. my manifold is very similar to one that I saw on this = site, I=20 think it was mounted on an RV4 running duel throttle bodies. Mine is a = turbo so=20 needs to be slightly different. Wish I could post a pic but my = picture=20 album program wont compress them enough to post! ( maybe operator error) = .
