My 360 with Superior IO 360 is ready for engine start up. The exhaust is a 4 into 1 built by Sonic Headers in Princeton, Mn. It is beautiful work and ceramic coated. Sonic provided me with a clamp to fit over the large pipe (collector exit). This will need to be fastened to the underside of the fuse in some manner, but I question whether it is necessary. The collector is bolted to two of the headers with stainless dogbones and 3/16 bolts. The headers are of course very solid on the block. The additional clamp would need to be rubber mounted to allow engine movement. I see no way the collector or any part of it can ever depart the plane. Is this clamp necessary? I just have completed the install of a 2 screen Dynon Skyview system with ap and Dynon txpd with traffic, Garmin SL30 radio to give ILS presentation on the Dynon screen. I have no steam gage backups. With dual screens, backup batteries and dual ADHRS I feel that I have enough redundancy. Does anyone have input or comment? This plane may be one of the first with no round gauges anywhere. Next issue, my battery is an Odyssy 650 (650 cranking amps) which has been sitting around for 5 years. It does not turn the crank fast enough for starting. Is 650 amps enuf for a 360 (8.5 compression). I probably need a new battery but don't want to buy one undersized. I really appreciate this website-very informative! I will post pics when the plane is together. Look for N360 ZG at Oshkosh!
