| re: the Odyssey batteries. Read the charging instructions carefully and make sure your charger conforms. One of mine got fried using a standard auto-charger. IMO although they have wonderful shelf life compared to aviation batteries, they do seem to be susceptible to over charging.

Here’s a question for Chris, Paul, and others with knowledge of L2 exhaust. 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 have been flying my O-320 with standard factory exhaust for over 1,800 hours without a clamp and without any problems. I do have the 2 exhausts strapped together with a stainless hose clamp over exhaust wrap. See post on 01/11/12 for a photo. 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.
I like backup steam. 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 have been using an Odyssey PC925 for over 7 years and it still starts the plane better than the new Gill and/or Concords that I had in the past. I have mistakenly left my master on for about 7 days. The battery was able to recover. I believe that Bill Harrelson uses a set of either PC625's or PC680's, one as main and one as a backup. Bill has enough for his O-320. (Bill pop-in).
I originally purchased the battery from B&C, model # BC100-1. The price from B&C is still good at $150.00.I really appreciate this website-very informative! I will post pics when the plane is together. Look for N360 ZG at Oshkosh!
