Ok, our A6 Avant is great but slow, even my wife complains...
Since the new S6 Avant will be mid 50's, Allroad almost the same and our's is a '00 w/13,000mls I decided to do following:
1. G2 supercharger
2. Oilcooler
3. A8 front brakes
4. Tip chip
5. 8x17 BBS with 225's

What do you think? Most of the ideas thanks to this forum and it's members!

I'd put suspension and brakes ahead of the s/c... and personally, I would go with porsche/brembo calipers over some stronger rotors instead of an A8 setup.

Otherwise, sounds like you could be building quite a nice avant!

All the mods go in at the same time! Suspension, no change (Utah roads...)

You could chip it for 300+HP and would not loose that much on the resale value. Just an idea...

G2, good choice. Much improvement. Just be ready to "own" the mod.


Skip oilcooler unless you are someplace really hot. Even with my G2 I'm only at 225 normal and 275 max racing (pretty much the range before I put the G2 in). Sythetic stuff is supposed to hold up to 300, and we all change the oil so damn often it hardly matters. Some people swear by the oil coolers and like to see their gague stay low - I really don't care. And I want it above 212 in normal driving to boil any water out.

Do something spendier on brakes, if you're not gonna do suspension.

Not in America...

What kind of touque does the G2 generate? Can the auto tranny handle it?

Torque back on the G1 was 260 ft lbs peak @ someplace around 4500 RPM, and the torque curve itself was, in anything, flatter than the stock 2.8. So it ran from maybe 240-260 throught most of the band.

I don't actually have current G2 dyno data... PES keeps tweaking and not publishing dyno data. 270 ft-lbs-ish seems about right given the HP bump fom 280-295 HP. G2 definitely feels more powerful.

Stock tranny is spec'd someplace like 232 HP and 215 ft lbs (don't quote me, it's in the archives someplace). So people keep thinking it's gonna break. Mine hasn't. Lots of people with APR III or PES G2 have been OK too.

I'm sure we're shortening the life of it though. I don't try to drag race the car, or launch from engine breaking at lights much. Because I don't want to be the first to find out where to torque converter fails.

Of course I'm guessing that it would be the torque converter that would fail. But perhaps all that happens if you over-drive the thing is that it slips, and the tranny ECU signals the engine ECU to back off. I've been meaing to get out there with VAG-COM and see if I see and enginer intervention request from the tranny to the engine ECU. 'Cause if I do, then the tranny, by protecting itself, is slowing me down... and we can't have that... PES, however, says they have seen no evidence of this hypothesis during their tuning, and I'm inclined to believe them.

Short answer. Yes, seems to handle it fine.

and the sevice guy told me that the tranny in my A6 avant is the same one used in the 4.2 and the 2.7T. If that is true then a G2 would be safe.

Good bet.
