    I have completed the connection from the filter discharge to the turbo inlet. It's a reasonably efficient number of elbows starting with a 6" 22 degree connection at the turbo to a 6" diameter aluminum pipe (8" length) to a 6" 45 degree elbow to a 6" to 7" reducing elbow to a 7" elbow into the filter.  What is not seen is the charge air cooling pipe that has been removed. The inlet port on the radiator where it connects can be seen on the upper portion of the radiator.

The connection to the turbo could really use an elbow of about 32 degrees but thats not easily found. The original connection was a 45 degree reducing elbow that only worked because it went to a smaller 5" SS tube. 

I think, I am as good as I need to be on this assembly. A 3D printed tube would be only marginally better. The real issue is the still to small filter element.  Once I get a feed tube from the filter to cooler outside air I will get a baseline and then be able to build a custom filter housing.
