thanks for informing me that you dont care
this has noting to do with track times, or HP on a dyno or anything you have stated, it was a simple question asking how much people have lost, that is all

You don't lose anything....your motor will still make the same amount of power...
Your drivetrain will absorb more according to a chassis dyno, and your ET will improve because if how a torque converter works
If you make less #'s according to a test, but you go faster... Did you lose or gain from it?
Why is it important to know how much power people lost if it has nothing to do with HP or track times...
Quit being contradictory to what you asked...
I gave an answer that covers what you asked in 3 different ways now.

no, you gave me answers relating to my car will be faster at the track and dyno numbers and so forth, which has nothing to do with my question
do i disagree with you and what you have said? not one bit, it is all right, am im not questioning what you said is wrong or right bc i know it is BUT it doesnt answers my question
if someone would have posted "i made 400rwhp with my M6 and then after the swap i made 385rwhp with the A4" then it would have been fine, im just wondering how much you lose VS a M6 that is all

I think you will lose 3-5 % RWH when changing from std to a A4
( STD lose 12-15 % RWH from FLY WHEEL HP, and AUTOMATIC lose 15-18 % RWH from FLY WHEEL HP)
just my $.02s Johnny ( any one feel free to disagree)

I believe a 4l60e is relatively efficient for an automatic and is more efficient than the rule of thumb 20% loss between crank and wheels associated with an automatic. Maybe closer to 15% as posted above. A smaller converter should also help by removing rotational weight assuming the converter is efficient near the top and stalled correctly relative to redline.
