As someone who has had an injector plug up, the concept of a single,
throttle body injector would make me pretty nervious. At least with a
port injection you have 5 or 6 cylinders taking you to the crash site.

I never really thought of these Ellison guys as throttle body "injectors".
More like a Weeping pipe in the airflow. Kinda like the TKS weeping wing,
but not. The pipe rotates 90 degrees and when the holes are facing the
airflow the fuel can't get out. Use the mixture knob to rotate the pipe and
the tiny bit of fuel pressure and the airflow not blasting into the holes
allows the fuel to mist out. Instead of a throttle plate they use a
guillotine type metal slide plate to reduce the throat opening. Weird
design.
