Angry Wind Tunnel kEpsilon Boundary Conditions

iamed18 is on a distinguished road
I'm looking to model a wind tunnel in which the sides are all freestream velocities with freestreamPressure boundary conditions. However, when using the models from the CFD-Online wiki
something goes awry and my results make no physical sense (speeds on the order of Mach 1.45, for one).

My setup is:
freestream velocity of 10m/s in the \hat{y}-direction
vehicle situated 0.5m above "ground" on the x=0 wall (extending to x=1), and 7m long in direction of wind


Can someone assist me with choosing boundary conditions for the vehicle, freestream sides, and ground?
