Would I be better off writing it to a stream, then using compression routines that support compressing streams then writing to disk. Seems it would speed things up somewhat. We are talking 6 meg text files here.

It would be much tidier, but not necessarily faster - Windows may never actually dump the file to disk during your current method.

Are there any simple examples how to write a text file to a Stream? 

That depends on how you want to build the file. I'd:

 list:tstringlist;
 stream:tmemorystream;

 stream:=tmemorystream.create;
  try
   list:=tstringlist.create;
    try
     list.add('Hello!');
     list.add('Line 2');
     list.savetostream(stream);
     stream.seek(0,sofrombeginning); //rewind before compressing
     docompress(stream);
    finally
     list.free;
    end;
  finally
   stream.free;
  end;
