steering ratio for S5 2 hole steering rack?

[Whizbang]

anyone know what the steering ratio (or even lock to lock turns) is for the S5 two hole steering rack?

seems like there is quicker rack in turbos (the same as all S4 power racks @ 15:1 or so) then a slightly slower power rack for the the other cars (17:1 or so).
