KR> Exhaust systems

For the first couple years of flying my KR I have been using a mild steel exhaust bolted to the original cast logs on the corvair.  I had them ceramic coated and they have worked very well as far as keeping temps down in the cowling and had not cracked.  Last year I tooled up and designed

Rob, This is really good information for anyone wanting to design their own exhaust. I'd like to know what books you are referencing as I'd like to have a copy on my shelf. As you point out, there are ideals and compromises. Just running 4 separate head pipes made it challenging to find

Jeff, I've been reading alot about exhaust designs and requirements. I'd like to share what i've found if thats alright. Perhaps some others can benefit as well if you already knnow this stuff. But, I might say that the reason for your better performance is in comparison to the old system,

N611GB turbo headers are wrapped in the fiberglass wrap in only a few places where the hot exhaust pipes come close to (hard) oil lines and oil filter. Later more sections may be wrapped if heating the cowl or other parts becomes a problem. There is doubt that it'll do any good as the flowing

Don't tell that to my to Bellanca's in the hanger. 1 is a 1947 and the other a 1974. The wing is all Mahogany. On the 47 they used 1/8  4 feet out and 3/32 the rest of the way. On the 74 it is 1/4  4 feet out and 1/16 the rest of the way. The airplane does not have any record of a wing

Many KRs have been built using Mahogany, and no issues with it. Steel is stronger than both. See N64KR at http://KRBuilder.org - Then click on the pics See you at the 2009 - KR Gathering in Mt. Vernon, Ill There is a time for building and a time for FLYING and the time for Flying has begun.

Rick I would agree with all of that except the mahogany ply. It does not have anything like the strength of Birch. We are not allowed to use it structurally in the UK because of this. Peter Drake Hereford UK - Original Message - From: To: "KRnet"
