Take it as a lesson learned.
If he din't get your name then it's unlikely you'll get anything further, however I suspect his language used was as a warning that if he had stopped you and done you properly for it then that's exactly the punishment you would be looking it. If you're not prepared to put up with the time, then don't do the crime. Everyone knows what the punishment for 100mph is, so why risk it? It's hardly fun or challenging.
Sorry, don't mean to rant, I was stupid when I was a kid as well (50 in a 30 for no good reason) and I got a very similar warning. It really brought it home to me just what I was risking for so little gain, hopefully it will do the same to you.
