Paul,

Here are some pics of the proposed  headers.  I am thinking about cutting
out
part of the vertical   tube that causes the double 45 degree tubes to be
used
to go around  it.  The system needs tweaking like adding slip joints and
designing  brackets to support the headers.  Appreciate any input.

That is about where you should start your ejector  outer tube
cooling air input bell mouth. Also you need to put a tapered  nozzle on
the ends of the exhaust pipe.

Joe,

Looks interesting.

I have two concerns:

1. The proximity between the pipe and the engine mount seems, from your
photo, rather small and since that pipe will be operating at a very high
temperature, it will probably severely weaken and  corrode your engine
mount at
the crossing.

2. unless the engine mount, in the picture is merely a trial and  will be
replaced or repaired, the corrosion that is evident on it is of  great
concern to me. If it were mine, I would consider it un airworthy in  that
condition. Perhaps an A&P might chime in here and possibly prevent you
from
becoming a statistic. If you have been flying with that mount, how did it
become
so corroded???

Just want you safe

Rhino or some other 3D program is very helpful in discovering these
problems before you build the motor mount.

Rich,

I am thinking about removing that vertical  member as it is close to the
tube.  I already took out the one on the other side for the water pump.
This is 1" X .065 wass tubing.  The mount itself has a little surface rust
and some primer over spray.  After all of the fitting and cutting and welding
is done, the mount will be removed and inspected.  if I have to make the
mount again it will be different design. With all of the changes and
research this has take a lot of time just to get this far.  I probably would
be flying for 5 years had I went with a lycoming.  The CAD drawings that I
have seen concerning the Long EZ are far off as far as space and placement
of components.  My engine is a little aft while the rad and cooler are further
forward as the hell hole is gone.  The thrust line on the CAD drawings seems
to be in the wrong place.
