APR 2.0T FSI DSG Stage 3
APR Stage 3 B8 A4 Quarter Mile| 01/25/2016
On Sunday, January 24th, we headed to Montgomery Motorsport Park to test our new APR Stage III EFR6758 Turbocharger System in the quarter mile. The car was driven to the track in its currently daily driven form, on street tires, with 93 octane fuel and a full interior, in an effort to show real world results most customers will experience on a day-to-day basis. Several passes were conducted, resulting in record breaking pass after record breaking pass. Ultimately, Trevor@APR, the owner of the vehicle, was able to achieve a email@example.com MPH after cutting a 1.733 60 FT time!
The fueling system was unmodified, resulting in power limitations below the capabilities of the turbocharger system. Temperature at the track during the record pass was roughly 50F, resulting in a density altitude of roughly -575 feet. Unfortunately, the negative density attitude did not result in a sizable performance benefit compared to running in warmer conditions due the fueling system limitations. However, beneficial to APR customers in warmer climates, the above results are still applicable.
As temperature drops and air density increases, so does the need for more fuel to satisfied the air fuel ratios prescribed by APR's calibration experts. To safely prevent the engine from running out of fuel in cooler conditions, APR's calibration experts have calibrated the ECU to reduce boost pressure while targeting the same power levels. Conversely, during hotter conditions, the ECU increase boost pressure
APR B7 RS4 Stage III TVS1740 Development Preview| 08/21/2013
Development preview showing the power difference between stock, our production Stage III TVS1320 supercharger system and a development calibration for the TVS1740 supercharger system. The final output on this run was over 480 AWFT-LBS and 510 AWHP on 93 octane. The calibration teams will continue to work on the calibration to smooth power delivery over the entire run while searching for more power on 93 octane.
APR 4.0 TFSI (EA824) V8 Ignition Coils for ~2013-2019 Model Year Audi and Bentley Vehicles| 01/19/2022
APR Ignition Coils are designed to be a direct plug-and-play upgrade to factory coils, and provide greater energy output, ensuring a stronger and more consistent spark. The commonplace replacement of factory ignition coils with those taken from the higher output Audi R8 is popularly believed to provide greater energy output. However, testing proves that they are no more powerful than the factory coils that are found on other engines. APR Ignition Coils increase energy output by up to 6% over stock. They are a direct upgrade or replacement, and come with a unique red housing!
