He didn't call it a turbo - he was adamant about calling it a homogenizer. Fuel was injected BEFORE the turbo
I got to speak with someone that worked with him many many years ago. He said the car worked great, got extreme FE and good power but it had one critical problem - it wasn't reliable. He had said the engine was being rebuilt quite frequently.

one of the first turbo'd US production engines i remember was about a '62 buick starfire. it had water injection. telling me that the first one was done right, and we have gone down hill ever since.

I personally wouldn't say requiring water injection means it was done right... WI is a band aid because there's too much heat. Perhaps the same setup on modern fuels with modern engine management on a modern engine would fare differently though
