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 License Plates and Frames| 06/15/2021
APR license plate frames and vanity plates are the perfect addition for any APR tuned vehicle! They are made from sturdy and rust-resistant T304 stainless steel. They are thick enough such they won't flop around like throw-away handouts you find in a typical swag-bag at car shows. They feature a fade and scratch resistant black powder coated finish with laser etching for the APR logo. Anti-vibration backside plate tabs keep it firmly in place. Four slotted install holes give you the perfect fitment with a solid connection to the car. The nice hardware hiders give it a clean finish too, hiding your unsightly plate screws. Fitment is universal. Some have said this product will increase the value of the vehicle, while others have made horsepower gains, but we can't comment on either.
