Earlier this year, Leo Alexandre, founder of Eurotek Tuning, wanted to prove that it is possible to build a dream car without having to spend an arm and a leg using Audi Performance Parts that are readily available to the public. In March of 2014, he set out to do just that by purchasing a 2011 Audi S4 S Tronic as the new Eurotek Tuning project car and installing Audi aftermarket products carried by his shop. Within just two months, the build was just about complete and publicly revealed at Wuste 2014. Continue reading below to see the details.
The Audi S4
The 2011 B8 Audi S4 comes stock with a supercharged v6, sharp handling, an attractive interior, sexy body and excellent fuel economy. It’s a stealthy combination of modern luxury and performance, producing 333 horsepower and 325 pound-feet of torque. With the S Tronic (dual-clutch automated manual), the S4 returns 1 mpg more on the highway. As a bonus, this model has a hidden “launch control” feature that will send the car flying instantaneously off the acceleration. That said, what more can one do to this dream car? In two words: A LOT!
Eurotek’s S4 Audi Performance Parts & Modifications
The Audi S4 is the perfect model vehicle for performance modifications.
The Tune: Upon purchasing the S4, Leo took it to his shop in Las Vegas, Nevada, where he immediately programmed it with APR Stage 2+ Tuning software. With this tune, APR requires installation of the APR Supercharger Pulley and recommends installation of a performance exhaust. Leo installed the APR Supercharger Pulley and opted to replace the stock exhaust with a Stassis Exhaust.
Exterior: Leo added a EuroGEAR Carbon Fiber Splitter in the front and a Carbon Fiber Valance in the rear.
Engine: Under the hood, the Audi S4 sports an APR Coolant Performance System and Stage 1/Stage 2 Carbonio Intake System.
Transmission: Popped on the 034 Motorsport Transmission Mount, a super affordable, easy-to-install, little piece of billet aluminum that eliminates drivetrain slop and results in crisp shifts and a smoother ride.
Suspension: Dropped with the Bilstein’s Coilover Kit and utilizing SPC’s Adjustable Control Arms to achieve just the proper geometry, the rest of the car’s performance suspension features a Eurocode lineup of Front and Back Swaybars, Front Swaybar Link, Alumnium Rear End Link and Alu Kreuz Chassis Brace.
Wheels & Tires: This newly configured beast sits on a pretty set of Neuspeed 19x19 RSe10 Wheels and Michelin 255/35ZR19 Pilot Super Sport Tires.
Brakes: The resulting spike in power and speed requires the ability to stop on a dime during any condition. The Eurotek’s Audi S4 Build includes Forge Motorsports’ massive 8 piston 380mm Big Brake Kit Big Brake System to achieve the correct brake balance.
Additional: Not much was done within the cabin, however, Leo did install the P3 Cars Digital Interface. It looks high tech, fits seamlessly within the cabin as if it were stock and, most importantly, helps measure performance. Finally to add a few finishing touches, the S4 also features a new front grill, an APR tuning badge and custom artwork designs along the sides to give it a more aggressive, yet polished look.
Results: Eurotek’s Audi S4 now produces approximately 450 HP. Aside from that, because of the intercooler, the car can be driven hard for a longer period of time, performing aggressive runs repeatedly with minimal wait time. At the end of the day, for a relatively affordable budget and a short build time, Eurotek’s Audi S4 looks more attractive, rides more smoothly with better handling, and possesses increased speed and power.
