Thanks for your 'splanation of turbos, and thanks to Adam for his very well written response. I have always wondered about why the turbo doesn't spool when not under load.

Nother question:

It sounds like a diesel is the most efficient at WOT than when it is not, because the amount of air would be perfectly matched to the amount of fuel the designers have figured would be at the final full throttle mix...? (does that make sense?)

Whereas the gas engine is more matched throughout its operating range because of the ability to vary air as well as fuel?

ARE diesels most efficient at WOT?
