Mildman,
The theoretical point where you get 100% thermal efficiency is exactly that, theoretical. What the original statement means though is that the lower the temperate in your exhaust (ie closer to the inlet temp), the more efficient the motor will be running. THat is assuming consistent fuel mixtures.
The less heat you are wasting out the exhaust the better as it means more of the energy has been turned into kinetic energy rather than heat.
It's been a while now but I believe that the most efficient a 4 stroke petrol engine can be is about 40%.
As for the turbo part, turbos do make an engine run more efficiently. Like you said they utilise that otherwise wasted heat energy.
