    Gentlemen, allow me to cut and past Arin@APR's post from a few other forums for you.... as you can imagine we're very proud right now with the results, and they are only getting better! Stay tuned for the R8, S5, S4 and RS5/RS4 performance figures and times :) I'm hoping to get the R8 on the dyno today, will post a video if I can later.


    On November 14th, 2013,
    We took one of our development B7 RS4 vehicles to our local drag strip. The goal
    was to test the upcoming APR Stage III TVS1740 Supercharger System. On the dyno,
    we saw incredible power figures that take the RS4 to new levels of performance;
    even over our previously available TVS1320 Supercharger System. To ensure that
    the dyno results translated into real world performance, testing was performed
    at Montgomery Motorsport Park’s drag strip. The drag strip testing was used to
    safely and legally collect quarter mile times and P-BOX GPS acceleration data
    (0-130mph times).

    Montgomery Motorsport Park, located in Montgomery,
    Alabama is an IHRA certified track with a flat surface and certified timing
    equipment. We’re currently analyzing the P-BOX results and will share the data
    at a later time.



    The
    vehicle is a B7 RS4 with a 4.2L FSI V8 and 6MT transmission. Mods to the vehicle
    are as follows:

    - APR Stage III TVS1740 Supercharger System
    - APR High
    Pressure Fuel Pumps
    - Magnaflow OEM diameter downpipes and catalysts
    -
    K&N Intake Panel Filter
    - JHM Stage 5R Clutch and Flywheel
    - TSW
    Nurburging Wheels & Michelin PSS Tires (46lbs each)
    - Hotchkis
    swaybars

    - OEM Intake housing/ducting
    - OEM catback exhaust
    - OEM
    suspension (springs/struts/shocks)
    - OEM interior, full weight, us
    spec

    Before we get into final power figures, price and availability of
    the upcoming APR Stage III TVS1740 Supercharger System, I’ll take a moment to
    touch on the required modifications:

    - APR Stage III TVS1740 Supercharger
    System
    - APR High Pressure Fuel
    - Upgraded Clutch

    The HPFP’s are
    not included in the kit because we offer them in two forms: brand new pumps
    rebuilt by APR or your existing pumps rebuilt by APR. The rebuild option saves
    money by using your existing housings.

    APR recommends an upgraded clutch
    to see the maximum potential of this kit.



    We were able to make our first pass at 12:08 in the afternoon with the density altitude (DA) sitting at -392.8 ft and steadily rising till around 3PM where it began falling again. We started with our local 93 octane fuel and 93 octane software and began practicing our launches. After 3 attempts we were hitting 1.7x 60’ times and were passing the quarter mile mark at 11.2x seconds at 122-123 MPH. The car was very consistent producing 6 passes in a row in the 11.1 and 11.2 range, including hot lapped passes (meaning running down the strip, coming back and running again with no cool down time.)

    On 93 octane with
    our 93 octane software our best ET the day was 11.156@123.11 with a 1.654 60 FT
    time and a DA of only -42.2 feet! Our best trap speed of the day was with an
    11.232@125.41 MPH with a 1.772 60 FT and a DA of -58.1 feet.



    Around
    4 PM we switched over to 100 octane to get in a few passes. Unfortunately the
    daylight was dropping and the track informed us we could only run till it was
    dark. We only had time to run several passes on 100 octane with very little cool
    down time between each run. Never the less, on 100 octane our best ET and trap
    speed was on our second pass, only several minutes after the previous run and
    was 11.070@129.29 with a less than stellar 1.802 60 FT and a DA of -155.5

    ft.



    Overall
    we were very impressed with performance given this was our first attempt in the
    RS4. The DA on our record 93 octane passes was very close to 0 feet and we
    believe with a lower DA, the times could drop. Likewise, with an improved 60
    foot time, we believe a 10 second pass is achievable on street tires and full
    weight, possibly even on 93 octane. We unfortunately do not have any data for a
    full high flow exhaust system and other common modifications popular to the RS4
    community, but hope to see results from our customers who’ve upgraded
    further!

    That brings us to the fun part!

    After only a few passes
    on 100 octane, we decided it was time to have fun before the track closed. We
    jacked the car up, drained the fuel, threw in 104 octane, installed our 104
    octane software, removed the passenger and back seat, installed drag slicks, and
    removed the factory catback exhaust for even more weight savings.



    We
    fired up the RS4 and it was beastly! Everyone at the track crowded around to
    make sense of this snarling Audi in the heart of American muscle land.

    We
    had less than an hour to get in a few passes before the track closed. The first
    run broke into the 10 with our top trap speed of the day at 131.67 MPH, but we
    knew it had more in it. On the next run we did a massive burn out and heated up
    the tires and were able to hit a 1.49 60 ft time, but a missed shift resulted in
    only a 10.7@130 pass. Eric pulled the car around, let it cool for a second and
    headed right back out. The next pull was his best pass of the evening, setting a
    10.606@130.89 pass with a 1.500 60 FT time and a DA of -528.2 as the sun was
    dropping. We were so close to 10.5’s but there wasn’t enough time to get in many
    more passes with any decent cool down time between. We were able to run 3 more
    passes several minutes apart and cut 10.6’s on each one with trap speeds ranging
    from 130-131 MPH.



    Thus
    far, this is the quickest and fastest Audi we’ve personally run at the track and
    it’s paving the way for more test sessions in the future. Weather and time
    permitting, we may see passes from our other supercharged vehicles such as the
    R8, S4, S5 and RS5, all sporting our upcoming TVS1740 Stage III Supercharger
    Systems!

    Go APR!

    Full trim is where it is at. It symbolizes real world application without the inconsistency of 100/104 octane, no exhaust, slicks et al. 11.1s is a great feat. Awesome work from APR. That clutch will probably need replacing soon(LOL). Imagine if they had down pipes/full or cat back exhaust and better and modified cold air intake...

    The mind boggles...

    Since you're in APR HQ, maybe ask Arin and the guys how far behind is the S4 B8 TVS1740 development going? Or has that taken a back seat since the RS4, R8 & RS5 is being finalised.

    You could also ask what indicative pricing will be on the new kit as well in Oz.. $20K ++ like the old one or less?

    They are all happening in parallel, in fact the S4 is on the dyno today again... can't comment on release date but it is close.

    Sorry no, you'll need to talk to Guy Harding on Australian pricing.
