Omnicorse has published this VERY interesting article:
http://www.omnicorse.it/magazine/27329/ ... e-dal-2009
in which CFD engineer Michele Schilardi gives some data about CFD vs windtunnel methodology, cfd usage evolution at Ferrari (from just 1 guy - to current 25) and some interesting numbers about downforce in the 2009 reg era, and other useful information, such as stating that current front wing produces 40% more downforce that the basic 2009 wing.
The data were presented in a semi pubilc meeting at ferrari some days ago - of course Ferrari won't disclose info that could give advantage to their competitors, so I think the real data are a bit different/higher, like when they said "engine power bigger than 600CV" in their car launch data sheet
The numbers for total downforce of front wing and nose could be interesting - they are expressed in N at 300kph; if you convert you get Scz values you have 1,4 to2,0 (140 too 200 points) which seems quite big compared to Imanengineer reference - it depends a lot of what you put under tha name "nose", itf it includes the t-tray or not.
40% anyway is coherent with the massive development of tha fw in this years
Also very interesting form the picture above the article the panel behind Schilardi, showing a cfd image with colors and pathlines
