Okay, I've worked together a little more info in the form of some rumors on the S4. First, we'd heard from an unconfirmed source that Eaton was the OE involved.

From another unrelated friend of the site, we've had further corroboration telling us "The new S4 will most likely use a twin screw four-lobe (twin Vortices Series) TVS Eaton Kompressor." That's two votes for Eaton.

That same FO4 (Friend of Fourtitude) said he's heard the term 333 hp. We checked all information with a source at Audi and the reply was "the power figure is close to what I've heard."

We'll post more as we hear it, but we figure that was worth a mention on these pages.

Thanks for the tip Hans!
Before this goes too speculative, I want to clarify that I've heard just a supercharger. Of course, I could have heard something incomplete, but FYI.
The VW Group has not done a TSI in a displacement larger than 1.4 liters from what I understand. Further, knowing about this project, I was chatting with Audi's head of petrol engine development at the event where I drove the Ethanol-run next-gen 2.0T (which won't use Ethanol when it comes to market).

Anyway, not saying anything about the S4, I asked about TSI as a German engineer from VW had told our VWvortex Managing Editor Jamie Vondruska that TSI should be applicable to larger engines with similar performance and fuel savings results. I shared that with him and he looked skeptical. He said they weren't experimenting with anything bigger at this time... and I doubt he'd be skirting the S4 thing since I didn't bring that up. Normally, if they were, I'd expect him to say they were at least considering it. He was certainly conversational about the 2.0T I was driving, so it's not like it was a stone wall conversation.

Twincharging is the only place i could imagine seeing a blower on a factory audi right now. VW has been experimenting with supercharging and turbocharging smaller displacement engines for more power.
