APR 1.8T Stage 3 GTI at the Dragestrip

Using the upcoming APR 4.0 TFSI Cast Exhaust Race DP and new APR Stage II ECU Upgrade, we set out to test the C7 S6 and C7 S7 in various configurations, ultimately resulting in two new and exciting records!

The S6 was outfitted with the APR Stage II ECU Upgrade, APR TCU Upgrade, APR Cast Downpipes, 93 octane fuel and all season tires on factory wheels at full vehicle weight. With a 1.733 60 foot time, the best result of the day was an 11.388@121.81 MPH. The heavier S7 was outfitted with the same mods, but ran with Sunoco GT260+ 104 Octane fuel and Michelin tires on APR Wheels, again at full vehicle weight. With a 1.678 60 FT time the best result of the day was an 11.019@124.61 MPH! The density altitude remained close to 0 feet all day according to dragtimes.com. For comparison sake, our best results with the factory equipped vehicle was 12.216@112.42 MPH and 11.628@117.83 MPH using only our Stage I ECU Upgrade, and 93 octane fuel.

Over the course of the day, we ran several times, backing the 11.3 pump fuel results. We frustratingly backed the 11.0 multiple times, mere hundreds away from our goal of a 10.9 on factory turbo. The video does not show the fastest runs as those were captured after the film crew left as they had prior Super Bowl Sunday obligations.

On the dyno, the Stage II ECU Upgrade, paired with the APR Cast Race DP offers a substantial leap in power and torque, which contributes heavily to to the faster times at the track. Stay tuned for the official release

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 12.124@115.13 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

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!

The APR GTS K04.3 Turbocharger System converts your 991.2 911 3.0T to the larger factory GTS turbochargers and includes our Stage 3 ECU Upgrade making the conversion plug-and-play! Up-to 615 HP and 549 FT-LBS of torque is available with no other modifications. Adding upgraded intercoolers bumps power up to 648 HP.
