The result is high power output, which as he said will result in a much higher speed.

I think the problem may be that you are thinking in terms of engine efficiency, rather than fuel mileage. A turbo engine, running with some boost very well may have a higher "efficiency", the problem is, it also has way higher aero drag because it is pushing the vehicle at a high rate of speed.


Maybe I'm thinking efficiency will improve mph too much. And i was thinking lowèr inHg was just making it easier on motor. Makes sense though now.....

What about same inHg though.
