So I finally had a chance to take my RS6 to a drag strip and see what it could do. What a let down. Car ran a 13.0X every time at 106.X MPH. I was cutting a 1.9 second 60' and launching at apx 5psi but the car would only peak at 9-10.2 PSI for the entire run. Checked all the hoses and vac lines then gave up and went home. On the way home we played a little (I was with a pack of Cobras and Machs) and I noticed at half throttle car had no issue pushing 18+ psi and holding it.
Car has older Milltek DVs on it, could they just not be holding at WOT?
I dont have a VAGCOM and wasnt planning on getting one since I am selling the car so I cant really check commanded vs actual BUT several months ago it could hit 18 PSI at WOT. And yes, I reflashed the computer and did the sneaky reset to no avail.
I should also point out that air temps were 95+ and my intake temps were at 188 in the lanes and didnt drop much during the run, maybe 20*. I heard someone say the DA was 3200 but I didnt check. Humidity was through the roof.
