Agreed I was refering to in the turbulence model you have the option to select compressability affects.  I didn't realize density based wasn't needed until 2-3. That is good to know.  Other then that not sure what else it could be.  Even if the reference values are wrong, as long as the same values are used every time as we increase from mach 1.2 to 5 you should see a spike in drag at the 1.2 case which we don't see
