Worx Wagon Never Ceases to Amaze!

Worx Wagon

Redline Speed Worx is Proud to Have Now Built The MOST Powerful 2.7T Tial 770 Equipped S4 !

After hundreds of man hours put into both building and refining our very own Worx Wagon, yesterday all of our work finally paid off.  After several rounds of tuning with our good friends at European Performance Labs (EPL) testing & tuning new modifications our efforts proved fruitful. We were able to extract 740 all wheel horsepower from our S4 on VP MS109 fuel.

We are happy to announce that we have now built the MOST powerful 2.7T equipped Tial 770 Audi in existance.

There is nothing better than coming into 40 pounds of boost on the street in thrid gear and having the station wagon go sideways as it looses traction.  Achieving this level of power from the platform was no easy task, which we have proved over the two years it took to assemble the S4.  One would think this would lead into the completion of the build, but here at RS WORX we do not stop.  Next on the to-do list will be an complete OEM RS4 body conversion all in an effort to fit 10+ inch width wheels to enhance our traction abilities.  Furthermore this avant was in no way shape or form to be built as a dyno queen, we will be upgrading and replacing all of the drivetrain components to allow this S4 to be extensively abused at the track with no worry of braking components.

Full video feature will be soon be released of the vehicle, which we hope will accurately demonstrate the aggressive raw nature of this subtle beast.

The build article on the Worx Wagon can be found here.

Results from the first round of tuning can be seen here.

A short build list of the upgrades and components currently installed in the Avant:
