[QUOTE=redpoint5;594358]I'm not buying a 25% engine efficiency improvement by simply running hotter; not even close.

Skepticism is good, but denial of someone's real life experience, with zero facts and zero experience to back you up, is simply being closed minded and willfully ignorant.
Calculating a 25% increase in engine efficiency is simply bad math.
43mpg to 50mpg is a 16.27% increase in mpg. 46mpg to 55mpg is 19.56%.

Going from a 160F thermostat/running temperature to a 230F thermostat/running temperature is a thermal increase of 43.75% .

Did you read thru all the info on the link to Smoky's Adiabatic Engine?
