Twincharging the 2.8?

Twincharging the 2.8?
Hey guys im a noob on audi forums and sometimes these crazy ideas come to mind so here you go.
Aircraft internal combustion engines have been using twin charging for a long time. There are some turbines that use twin charging also. For those of you who don't recognize the term, it simply means combining two different compressors together, either in series or parallel.
I was thinking... one day when I get myself another car and leave my B5 in the garage... why not try to super charge and turbo charge it? I read somewhere that strapping on both compressors wont make a difference if the ECU isn't tuned correctly. So assuming I find someone who would actually attempt to tune it, is it worth it?
The cost of a project like this is probably in the 10,xxx's but im interested in finding out if im the only psycho who thought about twin charging the B5.

1. Unless you have a strong attachment to your car, doing this would be a time-consuming, likely dead end project full of regret.
2. The twin turbo'd B5 is the 2.7TT in the S4 and the RS4. You'd avoid all the headache, custom work, and throwing your money into a sinkhole by selling your 2.8L and picking up a well-maintained S or RS.
3. The supercharger is a possibility with your engine, but finding one will be difficult and sourcing a tune(r) will be even harder, but you would get that awesome whine. I'd do this if I had a B5 (now I sound like Randy) and the opportunity.
4. This isn't exactly like all the other threads who want to turbo their 2.8L, but there is always a way to do something if money isn't an issue. If you hold onto your A4 that long, I think it'd be cool to sell it to an aspiring enthusiast in high school/college to get them in the scene from a generous guy.
5. You're talking twincharging, not biturbo, but 034 Motorsport put a bit of effort in R&D for a single turbo kit on the 2.8 A4 and the 2.7 S4

I don't know of any successful projects of this nature, but that doesn't mean it's impossible. If you want to do it just to say that you did it, by all means go nuts. If you're trying to make power with the 2.8 in a cost-effective manner, you're barking up the wrong tree. You'd likely need to do most of the R&D yourself, so keep that in mind. That said, this could be awesome.

^ This. I put all that info up there cause similar questions are asked about every month and the responses are almost always the same. If you did it, it would be bad ***, but do it for you.

Regardless, good luck if you decide to attempt this.

What would the point of that be? I have a friend with a chipped gti vr6 and I beat him every time we race, he also never stops complaining about how hard it is to work on.

If your budget is high enough, why not an S4/5/6/8 or a BMW M3 or something new(er) that won't give you a headache every weekend?
Still it would be cool.

This guy needs to get his act together and finish his build. 3 years and it barely runs. So much money invested.
