I'm not sure you are correct or not.
From a thermodynamis standpoint I agree that more heat would be produced, but . . . .
From a pressure standpoint fuel/ air mix is very nearly a spring. In an odd turn of events, I can coast in gear FARTHER than a 1.8t golf which was on similar rubber / pressures even though I have much higher compression (however I have less pumping losses due to no throttle plate . . . .
So I'm going with; please substantiate your claim, because I totally do not know the answer.
Granted I highly doubt that gasoline would benefit from super high CR, but maybe some other fuel would . . .
