APR B8 S4 11.1 Quarter Mile Pass with a 4,200 Feet DA!
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 Audi S5 4.2L FSI V8 Stage III+ TVS1740 Supercharger System Quarter Mile!| 04/17/2014
APR Presents the Audi S5 4.2L FSI V8 Stage 3+ TVS1740 Supercharger System!
In the factory form, Audi's S5 4.2L FSI V8 leaves much to be desired compared to recent models proudly displaying the S badge. The APR Stage III+ TVS1740 Supercharger System fills the void by adding an average of roughly 45% more horsepower and torque across the entire power band. The results are nothing short of amazing; taking the S5 from 353 horsepower to 589 horsepower on pump fuel and 635 on race fuel without breaking a sweat! With up to 542 FT-LBS on tap thanks to the TVS1740's positive displacement supercharger, expect instant acceleration with absolutely no lag commonly associated with other forms of forced induction.
APR Porsche 2019+ Cayenne S / S Coupe 2.9T ECU Upgrades!| 09/09/2021
We're excited to announce our Engine Control Unit (ECU) Upgrades are now available for the Porsche Cayenne S and S Coupe (9Y) 2.9 TFSI engine with the Bosch MG1 ECU! Expect massive gains with up to 484-538 HP and 521-590 FT-LBS of torque on tap, depending on octane, from this simple software upgrade.
APR's ECU Upgrades are the best dollar-per-horsepower modification one can make to improve engine performance. The upgrades dramatically increase horsepower and torque, making for an exceptionally quicker and more exciting vehicle. This is made possible through APR's optimization of the factory engine management system to take full advantage of the engine's capabilities, without needing any end user adjustment. The ECU Upgrades are available with various features and supported octane levels and each stage is compatible with most typical bolt-on modifications. The software is installed to the vehicle's factory ECU through the OBD-II port once the ECU is unlocked, resulting in a clean and headache-free install. Furthermore, for those looking for tuning with a limited powertrain warranty, APR Plus has you covered!
APR SQ7/SQ8 (4M) ECU Upgrade 4.0 TFSI EA825 V8 (North American Market)| 09/08/2021
We're excited to announce our Engine Control Unit (ECU) Upgrades are now available for the Audi SQ7 and SQ8 4.0 TFSI V8 engine with the Bosch MG1 ECU! Expect massive gains with up to 685-767 HP and 731-804 FT-LBS of torque on tap, depending on octane, from this simple software upgrade.
Our new suite of MG1 ECU software comes after months of extensive research and development that is typically absent from the aftermarket. Our upgrade makes the engine more powerful and more exciting. We’ve extensively calibrated the system to work flawlessly on the track, while retaining safety routines to protect your engine in the most demanding scenarios. This was all made possible by our engineering team's pursuit of perfection. Development vehicles were outfitted with additional sensors, including turbo shaft speed sensors, thermocouples, transducers, and more, along with our high speed direct RAM logging equipment, to feed valuable data to the team for analysis. After thousands of hours of testing and tuning we created new calibrations that are fine tuned for several octanes and contain hundreds of map changes, with a vast array of safety features built in.
