just picked up a new s4 any one know if there any after market super chargers for this car yet ?

 

It's very unlikely - I don't even know if there are blower mods like overdrive pulleys yet. Best bet to check is PES, since they make the aftermarket superchargers for the 30v V6 and other Audi engines. The car is so new that it's unlikely that the limitations of the stock setup have been determined, or even probed yet, so I wouldn't worry about that just yet. Check with the companies that make the systems for older Audis, and you may even get a score if you offer your car as a test/development mule for such a supercharger.

 

It must be nice to be able to so casually be ready to throw caution to the wind and void the warranty on your brand new car.

Cheers.

 

no need for a aftermarket charger on that car. the stock unit is a Eaton TVS, you really cant do much better. On the supercharger system we built for a 4.2 v8 we tried really hard to use that charger but couldnt. There are still some things you can do to have fun with it. We have been waiting to get our hands on one to work on tuning with unitronic and a water meth system.
