Did you ever order the SVT radiator? I know Terry Haines or Cardoc (or both) on FCO was saying that there was no difference, but I know what I read and I'm pretty sure someone can clear this up. I'm positive I read the SVT radiator was larger, I think its in the little handout that comes with the owners manual.
