This should stop some of the B.S. about what is faster (BMW, B4 S4, et). MTM has a supercharger upgrade for the RS4. Spec.s claim 120 BHP & 96 Lb/ft, and 0 to 60 3.9 sec. Boost is under 6 pounds, and they say very driveable. It won't be for everyone given the estimated cost of $25,000. For those that want it all here you go. This only the beginning!If anyone gets a chance to try it I would welcome feedback.

i'll take the stock power with a warranty, please.

the initial 2yr warranty of Audi. And MTM is a reliable company to take their word for it(in paper too). Since I read the "Audi driver-Jan2007" article about this, I'd like to mention that the tubro is on 0.4 bar only and doesn't alter the engines' characteristics or behavior. I'd say the engine would be OK, BUT the damn thing is expensive!! I don't plan to use one :-) but it sure is a good mod!! In the article, MTM states that this kit is primarily for the R8 (V8 engine) customers..

Again.. who cares. I prefer the RS4 unmodded.

what is the cost of a blown engine if you were to do this and it made a big boom.

as does Oettinger and Sportec. Just not in the US

That doesn't say much. Audi's German warranty is near useless.
