Comparing curb weights to horsepower and cost...
This is an often discussed&nbs p;set of data, so I thoug ht I'd get it all wrapped up in one post (for  ;those who actually STF :-)

A6 2.7T Man (1-bar ECU) & nbsp; 320 &n bsp; &nbs p; 3759 &n bsp; &nbs p;11.7 &n bsp; &nbs p; $21,000   ; & nbsp; &nb sp; 1795

<b>DISCLAIMER:</b> There is some obvious "swag" in these numbers, but&n bsp;I'm open to criticism for& nbsp;those who have made the
modifications, and can provide  ;better numbers. I found the&n bsp;"Estimated Costs" by taking&nbs p;the <u>average</u> price found on
AutoTrader and E-bay, then adding the list  ;price of modifications, and t he appropriate labor. The&nbs p;labor calc is definitely a&n bsp;big swag
in that I'm going off of& nbsp;what people on the forums have quoted, and some of the local shops here in& nbsp;the NW. Like I said before, if
you have more accurate numbers , I'm open to suggestions.&nbs p;
So what's the point of al l this? Good question...  ;My main point of doing t his research was to gauge  ;the "bang for your buck"  ;when
modding your car. The LB/HP ratio is a fun calcula tion that gives a pretty good interpretation of how "fa st" the car would feel.
Obviously there are other fact ors such as ability to co rner, gear-ratios, drive-train loss, and range of power, but there's a pretty&nb sp;
stong arguement that Stage III 2.7T (Tip or Man) should hold it's own against an RS6.
The "Cost/(LB/HP) Ratio" calculation isn't a ll that useful unless your&nbs p;only comparing two models. & nbsp;For example when comparing&nbs p;and
RS6 and RSK04 A6, you get 11% better performance from&n bsp;the RSK04 A6 for 37% less cash. Again, this doesn't factor in resale value,
longevity, and all that jazz,& nbsp;but I still think it's&nb sp;a prety interesting set of& nbsp;data. Plus, it's nice&nb sp;to have a basic summary&nbs p;of the curb
weight and horsepower of the&n bsp;variety of A6's we talk&nb sp;about. If anything, it's an other opportunity to get excit ed (or depressed :-p)
about modding your A6! I think my favorite outcome is&n bsp;the fact that a chipped&nb sp;2003 RS6 can still keep&nbs p;up with a 2006 M5! (alt hough
the M5 has a much more&nb sp;efficient transmission...).

Interesting post, just a few comments...
I think your "HP/LB Ratio" is mislabeled (it's showing the pounds per horsepower, not the horsepower per pound). Should be "LB/HP Ratio," no?
Also, I think (as others have pointed out) the prices for Stage III parts, suspension parts, and exhaust listed in your RSK04 conversion are way too high. Not a big deal, but makes the A6 look better if you lower the numbers a bit
Lastly, a general question for everyone, what's with the 3759 curb weight for the A6 6MT? When I had my car aligned / corner balanced, I came in at 4066lbs with me in the car. I'm pretty damn sure I don't weight 271lbs. Is curb weight calculated with an empty gas tank, no driver, and no spare tire? Has anyone else got the true weight of their car?
Anyhow, again, nice post...
