The Raptor that was test fired was a scaled version.

  That's the poorly-sourced hearsay. It was lower thrust, but that doesn't mean it was physically smaller. Most likely, it was operated at a lower chamber pressure, since the most difficult thing about Raptor is the crazy high chamber pressure. Also, Raptor needs to be able to throttle down a lot anyway.
