Careful - correct conclusion for the wrong reasons.... In the miles per gallon equation, there is no "time" variable. mpg is independent of time. If your engine efficiency stays the same all the time - it would take the same amount of fuel regardless of how fast you accelerate... But, efficiency changes with load

As for your question - I'll let someone else answer for a turbo My explanation won't be very eloquent
