APR Motorsport - B8 S4 P1 during Practice at Road Atlanta
APR RS3 Testing at Road Atlanta| 10/30/2017
Following our successful outing at the drag strip, we headed to Road Atlanta for some brutal track testing. Testing on a road course puts the vehicle through some of the most demanding conditions. The engine is run at full tilt lap after lap, putting it through stress otherwise not seen on the road. In doing so, our calibration team is able to learn valuable information about how the engine handles the increased power in demanding situations our customers may experience. We tested each mode, Drive, Sport, and Manual, and were happy with the performance. Our RS3 was outfitted with our development APR 93 and Ethanol ECU Upgrades (as well as stock), APR 19×8.5 forged wheels with a previously used set of Pirelli Trofeo R tires, and APR Development Lowering Springs at full vehicle weight. We use Motul RBF660 brake fluid.
Race Report from our Driver, Ian Baas:
Thanks for a successful weekend everyone! The Car and Calibration was perfect and I've never been more excited about an APR release in my life. Most production street cars I've tested almost always show their weak points within 5-10 laps of any high performance track event. The RS3 Sedan excelled during the entire test and I am sure this product will perform flawlessly in street conditions as it sits currently!
I really cannot stress enough how much this car exceeded my expectations!
Best Time: RS3 Stage 1 (93 Octane Map) 1:45.60 (RA Wet/Dry Conditions)
S3 Stage 3+ (93 Octane Map) 1:39.10 (RA Dry

APR High Pressure Fuel Pump (HPFP) For the EA839 2.9T and 3.0T!| 02/26/2021
The APR High Pressure Fuel Pump (HPFP) increases maximum volume of fuel the HPFP can deliver by 37% over stock! In doing so, the direct injection fueling system is capable of satisfying fueling requirements set forth by high horsepower setups. This is accomplished by increasing the displacement of the pump using high quality components to exacting tolerances. On the B9 2.9T we achieved an additional 37 AWHP and 50 AWFTLBS over our Stage 1 (E85) ECU Upgrade by adding the pump and running our Stage 1+ (E85) ECU Upgrade!
