There have been several good threads on here recently that inspired me to add something (hopefully) also useful.
I added a reinforcement to a cobra elbow to try to prevent it from sucking closed under high airflow. It's a length of threaded rod with washers and nuts on the insides and outsides. It goes across the narrowest point of the elbow, just above the 90 degree bend. When you flex the elbow by hand, it seems that this is the spot most likely to collapse.
The threaded rod is small diameter (10-24?), so it shouldn't have much effect on airflow. I drilled holes in both sides of the elbow that were small enough the rod had to be forced through, so no air should leak. The washers and nuts are all loctited, so nothing should ever get sucked into the turbo. Just squeezing by hand, it seems this has made the elbow a lot more rigid.
Nothing that major, but maybe helpful to someone.
