Haha.. so the A6 is faster by a Little hair!!!! How bout A6 2.7TT Vs. the A6 3.0 Engine???

 

I suppose if I would of got the tip chip as well I would have shaved an additional 1.6 sec. 2 shifts before 60 = decrease of .8 sec per shift.

 

Panzer how did u come up with 30%

 

It probably isn't 30%...that means we're talking about a decrease in 0-60 time of ~2.5 seconds, which would place us in B5 S4 territory.

I can say with some authority from personal experience that my car cannot take a B5 S4. It's probably more like 10-15 percent. I can hang with my friend's 92 S4, which is about 230hp, 250lb-ft, 0-60 in ~6.4 with him driving. I can't beat him, but I don't get embarassed, and he doesn't pull too far ahead.

Ok, heres power to weight specs: A6 2.7T is 3836 pounds, manual. It has about 250 hp, which works out to 15.3:1 power to weight. That's 15.3 pounds for every horsepower. B5 A4 chipped has ~200 hp, and weighs 3241 pounds (quattro manual;add 100 for tiptronic, subtract 200 for FWD) which is about 16.2 lbs per horsepower.

So an A4 is slower in a straight line.
