Yep, the bottom line is the car is too expensive at this point and with the limited number on the
market who would be willing at this point to go for such an upgrade, it does not make much sense. On the other hand custom software tuning is not as expensive. Jeff Moss did that for me and was very fair. In another year or two this may become more of a realistic option. By then, most people have either worn out their B5s or are looking for something different. Someone should be forward thinking and have the first kit available and all the bugs worked out. It may take a good year or so to get that accomplished.

you won't get any power at 2200-5500rpm
at 2200-5500rpm it will just run like a S4.
once you in the 5500rpm range, RS4 will rocket.
Some people may not like it becasue no way I will keep that kind of rpm when driving local.
If you expect big low end torqe "feeling" RS4 is not for you. (i.e. local and freeway driving)
If you love cornering, driving road that allows you keep in high power RPM range (curvy), RS4 will makes you wet your pants. Straight line acceleration at mid to high speed is kinda dull but still pretty impressive.

Agreed. The turbos make you lazy;) An NA engine requires you keep it in the power band to really go.
Just going from 2.0T A3 to any of our other NA cars, there is always a period of adjustment as I need to remember to downshift. By the same token, when I drive the A3, I get annoyed when the steam runs out around 5000rpms - I'm used to there being more power the higher I go.
For track work I prefer NA any day. Lets you decide just how much power you will dole to the wheels when coming out of a turn based on rpms alone. With a turbo car you need a nice clear boost guage and one eye on it at all times.

It's a gamble. Just depends how much they want to invest, and how long they want for it
to take to pay off. I can't speculate what Jeff's priorities and long term goals are. IMHO, the meat of the biz is in chip tuning for the 2.0T and now the upcoming B8 tubo S4. I know that is a sure fire market I would chase when it comes to putting bread on the table. Forced induction for the RS4 is a nice feather to have in your cap, but the high profile nature of such a task not only gives opportunity to gain positive PR, but it also means any glitches will be high profile as well. It can be a liability unless fully committed with the right resources and backing.

The car in that video was a one-of-a-kind prototype produced some time ago......
And the engine failed very quickly. That's the reason the kit isn't being sold to the public yet. Long term reliability just isn't there.

Some great points here. An alternative would be to.....
take an existing product like Milltek DP and cat-back then do a software tune with these particular products installed. In terms of bang for the buck with regards to R&D, as well as consumer cost, this would be the way to go. Also, it's unlikely that any achievable gain in NA power would necessitate any other real modifications. I think, at best, with ECU tuning and DP/Cat-back, you are looking at 30hp max. Easily managable by an otherwise stock RS4.
