Well, Dad went out and decided he wanted to hang with his two sons in the world of speed again. He bought a 2001 A4 with about 11K miles.
I know there is a big difference in performance between the M6 and A4 so I really would like info from the A4 guys.
If you have any info on before and after times or dyno numbers for each mod, can you start listing them?
We have to start somewhere I guess.
Thanx

Actually, stock for stock, there isn't much difference. In first gear and with the performance axle, the A4 has 5% superior gearing than the M6, thus counteracting the torque converter's additional loss. After that the A4's quick shifting keep it competitive. It really comes down to how well the M6 driver shifts.
Once you start getting into mods, however, the M6 is superior unless you mod the automatic transmission as well.
As mentioned above, the "stock" difference between the A4 and the MN6 isn't that great. The MN6 is probably more fun to drive, but I love my A4.
I estimate that I gained 15-20 RWHP by adding a Vortex cold air induction and by adding a Borla Stinger exhaust system. Most of this gain, however, was from the Vortex.
A good torque converter SY3500 if your'e going to be running street tires or an ST3500 if you are going to run DRs and 3.42s or better yet 3.73 gears will make a tremendous difference in your cars performance.
Thanx for all of your input. I know I have to do something. After having 2 M6 trans ams, this will be my first experience working with an A4. I am amazed at the performance gain with a torque converter. I know almost everything there is to be known about the LT1/LT4 engine. Now I have the reason to learn about the LS1. Is the LS6 hotcam a good cam in conjunction with all the other mods you mentioned? With the emergence of the imports, I can't have dad out there getting beat by heavily modded turbo eclipses or talons. Most of the mods I will probably get done without his knowledge.
