Very fair, and I enjoyed taking a look at your references.

It is fascinating how complex the technology is. Each study looks into one characteristic (as is appropriate), but none appear to address the overall functional question in which we are interested.

Perhaps there will be a study of medium displacement turbocharged direct injection engines.

Then again, probably not.
