Sparks, you are correct if every thing is the same, but exactly the same, cam, chamber shape, etc. the saving factor is the alcohol fuel.
I don't think CNC meant the hot exhaust temp on a turbo is any different than temps on any engine with every thing the same.
The intake temps are the same and the exhaust temps are equal on both setups. EGT temps have no effect on the combustion temps only ignition timing, A/F ratio, pressure and design effects the combustion process.
Ignition timing is the easy way to control peak pressure.
Actually a turbo compressed air is cooler than a roots blower because they are more efficient in compressing air.
