Dyno result with the A6
Just finished geting baseline for my car, totally stock. 337hp at 6000, 341ft lbs of torque and 4500. 3 runs where done, the first in 3rd the next 2 in 4th. The 3rd run was the best. Looking at the A/F chart the car runs fat from 4000 rpms to redline, 11.7 at 6000. Anyway thought I would share.

Thank you for the info/results, I was curious what it be with the new trans, seems right in line with the A4 cars. 
Tough call as to which gear to dyno in with the lack of a true 1:1 ratio gear.

Concerning feeling doggy, nope. Gearing falls between the standard MN6 and the Z51 MN6.

As for rwhp, almost ALL automatics have dyno'd in the 330-345 range, some as low as 320 even, 337 seems quite normal to me.

sorry fellas for the confusion and not being clear...
im just brain storming out loud... coming from Z06 that dynoed almost 370 with just air filter...
and 2.86 rear axle gears is just way small for this car (2006 A6 that's what's coming towards my way)...

Gearing is just part of the story. Even if they are geared the same the manuals will probably walk the A6 because the auto is giving up HP, probably about 20HP.
But you are not going to change that much with a rear gear change. Change it enough to get a good 3rd and 4th is going to kill first. Anyway we will see what times I can put down when the track opens up in March.

What kind of speeds are you going from a roll that youa re starting in 3rd?
My car with the A6, was door to door or pulling on a C5 wiht a converter, exhaust, intake and TB.
I wanna line up with a M6 and A4 guy in the MD area. I bet it's all driver, in fact I bet me in an auto takes the average manual driver every time. My car is bone stock, bring your bone stock car and lets do this.

Concerning feeling doggy, nope. Gearing falls between the standard MN6 and the Z51 MN6.

I would think the best bang for the buck with the A6 would be a different stall converter and and tires. After that adding more hp. I don't know what 135 trap speed would be in ET but my guess is you would be knocking on the 10's and only need 2 gears shifts to get there.

3 speeds in an automatic are all you need to get the job done, the rest is just dead weight, at least until you want to cruise.
