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:

Engine:

  • The engine was completely balanced & blue printed and rebuilt with all new components. Any seal, gasket, nut, bolt, stud that could be replaced was
  • Block was ultra-sonic cleaned, inspected, and machined
  • Engine was bored over to fit the 81.5MM Mahle Motorsport Pistons and Forged H Beam Connecting Rods with ARP Hardware
  • Crankshaft was cleaned, inspected, and polished

  • Modified OEM RS4 Intake Manifold ( We have almost doubled the internal plenum volume )
  • All the accessories have been replaced ( AC Compressor, Alternator, Starter, Power Steering Pump ) - NEW OEM Audi

  • The Intake Manifold, Intercoolers, and Intercooler Piping has all been Thermal Coated with an Ceramic Coating to increase cooling efficiency by up to 25% over a non coated piece.
  • The exhaust manifolds were not modified in any way other than ceramic coating them.
  • We have deleted the belt / clutch driven radiator fan in favor of a high output electric unit.
  • The vehicle is running a complete Mocal External Oil Cooler, which works amazingly well

  • 034 Motorsports Bosch 044 Intank Fuel Pump
  • Intank 044 feeds a Radium Engineering Surge Tank / Double Pumper Fuel System.  Radium's fuel system utilizes a 1 Liter Surge tank that feeds twin Bosch 044 Fuel Pumps that are then tied inline into a -8AN Hardline fuel line which runs the length of the vehicle to the engine
  • Radium Double Pump system as been installed into the cavity underneath the vehicle where the factory charcoal canister would be located.  This results in a 100% safe location from both the interior cabin as well as road debris

  • We are running European Performance Labs High output EV14 Bosch Fuel Injectors

Drivetrain:

  • The factory 01E 6 Speed Transmission was completely diss-assembled and inspected for any possible damage
  • We completely rebuilt the transmission with all new seals, gaskets, syncro's / springs, 1-2 slider assembly

After reading all of this we know you are thinking this is a fluke or some sort of freak occurance. Well all we can say is this is without a doubt no freak accourance!  

There are several other 2.7T big power builds that are completed and / or near completion, with identical builds.  More PROOF of POWER is in the works ! It's not all about air ride and expensive wheels any longer. . . We are bringing PERFORMANCE back!
