Reports on Burtz new engines

[rotorwrench]

Aircraft have been using CRES type tubing since the WWII era. It turns brown over a fairly short period of time. It's certainly too much work to keep polished. The systems also need very good support due to the weight. They erode more than corrode but tend to crack when they get thin.

Model A cars already had issues with the exhaust manifold tending to slump down on the heavy end and a lot of that is due to the weight and arm of the exhaust pipe and muffler. Ford should have supported the pipe in front of the muffler as well as behind but they never considered it and issue. They likely didn't figure that so many of these cars would survive as long as they have,

Henry did think about it. They added the gland rings to keep the manifold located. I think early cars used one in every hole later ones are just in the end holes of the exhaust manifolds. https://www.snydersantiqueauto.com/p...1312&cat=41892

What they really should have done is installed another stud on both ends of the manifold instead of relying on the two center studs to support it.

Hmmm, wonder if I can get a Y-Block manifold to fit...

If you had a Dodge block you could stick a Y head on it.
