Weather station registered +3,000 FT density altitude with +80F temps, high humidity, and low pressure with a storm approaching.
"Over the last few months my RS7 has been residing at APR with some upgrades in the works.
They have made incredible progress and I am VERY happy with the results. The basic changes are stock turbo's reworked by TTE, new APR inlets and Roc-Euro intake, APR cast Race DP, and Miltek exhaust. The remaining important part is tuning which is phenomenal! Power is steady at 765AWHP / 775AWTQ on 104 Sunoco. Pump gas was 680AWHP / 725AWTQ.
We went to the Montgomery track yesterday and I have to say they do it first class. We made many, many passes and the numbers are below.
Best pass was 10.348 @ 135.56mph at 2.52pm when the DA was registering over +3,000.
If I could get better traction we could have gone faster.
We started with some M/T drag radials on the rear and the car didn't like them so we put all four Forgelines on and she picked up. Wheels are 20 x 10" Forgeline GA1R with 295-30 20 Michelin Pilot Sport Cup 2. They are sticky but not enough.
All the seats are out with the exception of a Tecnocraft carbon fiber driver's seat.
Lightweight lithium battery.
If you want to ask specific questions about the upgrades and cost etc. you will need to contact APR direct. They do a great job and may still come out with more parts that further enhance the performance of this set up. I am a very happy customer and can't wait for some better weather and DA.
