| VE and HP/L are closely related, not synonymous. Your cause and *effect argument that I'm incorrect clearly refutes the idea that they are synonymous, as you explicitly state they are two functionally different metrics. 350Zs look like ass. I never took issue with your conclusion, just how you stated it. I agree with your assessment that the VQ is probably more volumetrically efficient than the NA VG. Was the initial VG designed to maximize turbocharged application efficiency? If so, could they have made up for that by designing the intake tract specifically for a NA application? Why haven't they figured out how to get more power out of 3.5 liters? BMW makes 333 hp with less displacement in the current generation M3. The individual throttle bodies help, I'm sure. I think the real question is: Why hasn't Nissan figured out how to make more hp/L gain than 7hp/L in over 17 years of engineering. Horsepower isn't the final goal, and I think a few other metrics should be considered. Emissions at the tail-pipe restrictions are more strict, gas mileage requirements are higher, gearing is different as well (moot for hp, but matters for other variables). Focusing just on the hp/L of an engine, again I think leaves out so many variables, that it's a worthless measurement. A comprehensive overview of at least the items in this paragraph would give a better picture of what's really going on in an engine comparison.
