Audi S7 4.0 TFSI Quarter Mile - APR Stage I vs Stock

The APR ECU Upgrade for the Audi S8 is generating a tremendous leap in power over the already incredibly fast setup from the factory. You can read more about the upgrade on our product page:

Yesterday we decided to see how much of a difference our software makes in a quarter mile acceleration test in several different forms. We tested with no modifications at all, other than replacement Michelin PSS tires for our factory 21 inch wheels.

In completely stock form the car put down impressive times as seen below. With 93 octane in the gas tank we also tried our stage 1 ECU upgrade and later filled in 100 octane, switched to our 100 octane race program and collected more data.

The results for such a large vehicle were nothing short than outstanding. We ran all runs in Sport mode with ESP off and Dynamic mode enabled. We made sure to turn off the air conditioning, including the massaging air-conditioned seats.

The results were as follows:

11.909@116.76 MPH with a 1.837 60 FT - Stock 11.174@123.01 MPH with a 1.769 60 FT - APR Stage 1 93 10.937@126.31 MPH with a 1.748 60 FT - APR Stage 1 100

For the gear heads out there, this was performed at Montgomery Motorsport Park. We rented the track for the evening so it lacked the traditional prep and track temps that typically aid in getting the car off the line a little quicker with less wheel spin. Nonetheless, the car performed amazingly!

The vehicle was full weight, minus the spare tire too. Based on the time stamps and local we

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

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!
