this will be my first v8 I have ever owned, one of the other bigger capacity cars I have owned was a 1989 325is (m3) and I loved the sound/power of the 2.7l straight six bmw motor since then its been a mixture of audis 1.8ts and a freelander v6. My current 1.8T is pretty strong but its at the point now where I will need too go BT to get more power where as the s4 stock has more kw than what my modified 1.8T has, although the 1.8T does feel faster I have fallen in love with the deep grumble of the 4.2l V8. I have been modifying cars and bikes my whole life so its not going too take me long too start modifying the v8. In my head its probably going too be intake, branches, exhaust, cams and as with every other NA motor I am sure those mods will release some hidden potential in that motor.

I5 >> 2.7tt > v10 > 4.2tt > 3.0sc >> 2.0t > 1.8t
So your saying that the 2.7tt is better than the v8 twin turbo found in the rs6? Why is this so?

ease of maintenance Smiley

pulling the motor for a turbo swap is one thing. pulling it for an O2 swap...

but in all seriousness, i love the 4.2tt, but my heart still yearns for the v10 and i have a soft spot for the 2.7tt

I would say the v10 5 liter twin turbo in the new rs6 over the 4.2 v8 twin turbo however I have never worked on either only the 2.7tt however I can imagine a lot more ponies from the other two...

I really lusted for those cars.  Until every RS6 I looked was found to be burning oil.  Sad

sorry to dig up my old post BUT i have finally managed too read the file from my NA v8, the file is NOT stock however and I have a couple of questions. From my 2 stroke bike days too increase low end torque we would increase timing ie more timing more torque. Now this modified file on my NA v8 looks like the tuner has lowered timing which doesnt make sense too me. I am battling too find the fueling maps like LAMFA in the file so cant really tell whats been done to the fueling. Also KFMIRL has been lowered but IOP has been increased  Huh

my current tuned file

Timing has probably been lowered as the the timing is very aggressive out of the factory, at least the European spec is.

thanks Rick, about the timing surely to make more power more aggressive timing is needed?

Yes, but if you are already at the knock limit then you can't run more timing.
