I think you need more air in as well as more air out

the twelve-cylinder 2001 750iL weighs 21% more than a 540i/6, yet its  
V-12 only puts out 12% more horsepower and only 11% more torque, thus  
the 540i/6 is a far faster car, 1000 lbs lighter with  a lower rear  
axle ratio. The bigger cars are geared much taller for quiet luxury.  
The MSport has an even more extreme 3.15 to 1  rear ratio - it sucks  
gas because of the high revs but I still got 24 mpg at an average  
84.6 mph over 600 miles. I would flip rear ends on that 740 series  
before putting a high flow element on it, altho it must be said that  
the frequent precip makes Seattle's air about as clean as it gets ref  
particulate matter.
