Ferrari Mailing List: Re: NFC BMW 740

[LtWacko (LtWacko]

A 7 is a 7.  I know about the prowess of the 540 having owned  several.  The 
"peak" hp you are quoting also doesn't tell the whole story  of the power 
band.  Actually drive a 740 versus a 750, then talk to me  about only "12%" 
more 
hp.  You are correct that the 540 is faster, but they  are two different cars.  
I want power in a big car.  If I wanted only  speed for the money, I'd be 
driving American...
 
As for filter, is 5 hp in a pig of car like mine worth longevity?   That's 
what I'm asking.  When the paper element is new, very little gain  seems to be 
had with a replacement in tooling around town.  I drop in a  K&N element when I 
track the car.  Yes, I have tracked the 740  "iL".  If I want to go fast 
around the track for fun, I use an E30  325is.  
 
If you are worried about MPG, one shouldn't be driving a luxury make.   A 
friend (who traded his E38 sport for a Charger SRT-8) and I were discussing  
this 
recently. "If I wanted to save gas, I'd drive a prius."  The  "downgrade" in 
luxury from a 7 (or his haulin' ass V8) to a 3 series "is just  not worth it 
for 5 MPG."
 
Have you seen the cost of the diff versus the filter?   LOL

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.
