OK, now that we're looking at the same image, it's time for you to realize a few things...

1. Highway cruise is done in a narrow window between 2000-2500 rpm on the X axis and between 0-40 BMEP on the Y axis. In this region, the maps are EXACTLY THE SAME between the two motors.

2. 0.42 BSFC can be accomplished with either engine DURING ACCELERATION OR HILL CLIMB ONLY by putting your foot 80% to the floor and shifting at 2400 RPM. The turbo engine will simply allow you to accelerate faster, but will use no less fuel per unit of power produced.

Now, Duffman, for the third time, please go on and explain to us with your own map as an example, why P&G is more efficient than single speed cruising.

John, if you're wondering why I'm getting ticked, it's because someone who doesn't understand what torque is, is trying to school me on BSFC maps, insisting that an entire axis of the map is irrelevent! Ironically, he claims the Y axis doesn't matter, but a turbocharger stretching the regions along the Y axis does matter. Go figure! Guess what buddy, torque decides if you're getting 0.42 or 1.7 FC @ 2K RPM!!!
