Are gas engines ever going to catch up?
Our creaky old Cummins powered truck (bought used) seats 4, does about 20-23mpg bobtail and 12mpg towing a 5th wheel trailer at 22,999lbs. It's mileage is somewhere in between hauling a camper and/or...

Turbo'd engines of any fuel are more efficient than naturally aspirated counterparts.
You keep on saying this but it still is not true. BSFC is ALWAYS higher in a blown engine. It takes energy to compress air and that energy comes from the fuel.
I have challenged you before to produce a link that proves your contention that a turbocharged engine is more efficient but I'm still waiting for that link.
I'm hoping in a month or two I will dyno my personal blown engine and I will post the BSFC for you and others to see. I'm still debating whether to dyno or not.
About the 14 to 1 engine. Power and mileage is not linear with compression. IOW's you will get quite a bit of power and mileage gain going from 8 to 1 to 10 to 1. Smaller from 10 to 1 to 13 to 1. Above 13 to 1 very, very little gain for a gasoline engine.
