DDS is another thing that I personally am glad I don’t have only because I’m going to do coil overs eventually, and not having DDS saves me money there too. But it’s all dependent on what your plans for your car is. If you’re gonna leave the suspension stock, the DDS is great for a little extra stiffness when you want it, and luxury when you don’t.
AFAIK, the Q50 has a very good coefficient of drag (Cd) of 0.26-0.28
Stock turbos just can’t maintain the boost so the taper down towards the redline
Considering the recirculating valves instead of blow off valves, isn’t that a good thing to avoid turbo surge? Or am I thinking about this wrong? Seems to me if you want to build boost all the way to redline you should have BOVs.
Since @Kraken and i have the same car, bolt ons and tune...different flavor, maybe...our results should be similar for the Vmax numbers and 'touch and feel' at speed.
I got all that confirmed for stock new 21 'straight off the lot' new with supporting whp and wtq #s, with numerous testing over a years time...all different temps and conditions, the top capabilties are consistent and repeatable.
Decide to put the spurs to old girl...she clocks in and goes to work every time.
I had the oppurtunity to 'lean into it' some and start getting a feel for the the new horizon, as the car sits now.
Can confirm @Kraken picture, with the comment 'there's more.'
Car was still pulling when i lifted, with a quick glance at speedo, as the opportunity presented with no plan or goal to determine the top limits as yet.
This picture is my addition to the topic, gathering data. There's still more.

2-4 mph per hour less for actual vs indicated, the gap slowly widening, as velocity increases.
Hey DeeCee, how fast have you reached on the Autobahn.
Interesting - thanks for the info. Speeds most of us will never see in this car anyway, but I was just curious.
