Interesting adaptation, but I'm always wary of unique engine designs. I think engines are validated once an OEM latches on to the technology.
The website claims a engine efficiency increase from 33% to 40%.
Cummins
claims an engine efficiency increase through turbocompounding a diesel from 42% to 46%. Cummin's (Holset's) technology has also been applied by an OEM: Scania.
These designs are always inspiring for me to develop my own crackpot adaptations.
