Staging A Proper Audi S4 Build

Any fan of Audi knows that the 3.0TFSI Supercharged engines are incredibly stout, well designed, and quite underpowered given their potential from the factory. This particular customer’s vehicle, a beautiful 2013 Audi S4 is being put together from start to finish by a very discerning customer who wants to appreciate everything in stages. Looks came first for this vehicle so the customer had a unique carbon fiber “ducktail” spoiler installed along with a set of custom 19 inch wheels and a BC Racing coil-over suspension to lower the ride height of the car. You know the saying; “decrease the altitude and increase the attitude!” With the benefit of a lower stance came better handling and far less body roll. You have to admit, it looks really good!

Next up was brakes. The Audi S4 comes with rather potent calipers stock from the factory but the OEM rotors, pads, and rubber brake lines just weren’t cutting it. Velocity Factor put together a “staged” brake upgrade that consisted of StopTech Slotted Rotors, StopTech Stainless Steel Brake Lines, StopTech / Centric ‘Posi-quiet’ ceramic brake pads, and Motul RBF brake fluid. These components are far more durable than stock to begin with so they will last much longer. The combination of the slotted rotors and ceramic pads increase braking power while lowering the amount of brake dust given off to keep the wheels cleaner, and the stainless steel brake lines don’t swell under pressure and heat like the OEM rubber lines do. This results in a much firmer brake pedal under all conditions and the components ensure consistent and much better braking power all the time. The Motul Fluid has a much higher boiling point than the stock fluid and in the Florida heat, especially during the summer months this is a huge benefit as well.

Finally, an AWE Touring cat-back exhaust system was chosen and installed. The deep, rich, sporty tone makes a tremendous difference vs. the stock unit and the increased breathability results in a slight bump in power as well. Along with this, the polished double-wall tips replete with the AWE Tuning logos look amazing! When the customer drove away he immediately called back to thank the staff here at Velocity Factor for helping him choose the right components along with the best installation. To say he was happy would be a huge understatement!

Next up for this customer will be a Unitronic Stage 3 ECU software, Stage 2 DSG software and dual pulley setup (both supercharger and crank alike) that will elevate this car to over 500 Horsepower and over 450 lb. / ft. of torque. The AWE Downpipes will likely be installed at the same time along with a Forge Motorsport Chargecooler Radiator and Expansion Tank Upgrade that will fully divorce the existing system and allow the car to make consistent high power while reducing the risk heat soaking with increased recovery speed times. Needless to say this Audi S4 will be ready to take on some major players when it’s all said and done. Stay tuned for the next chapter in this vehicle’s upgrades here at Velocity Factor!
