The summer going into highschool, my son's team had 4 pitchers who could throw 80. Three of them are going to be pitching D1 next year, and the other will be at a solid D2. So, I would say your velocity is on track. As seniors they sit around 90.
As has been said you need to keep working hard and improving. It's a big jump from 80 to 90, especially if you are already close to physically mature.
Most importantly - grades. Every one of those pitchers is a good student, and one is going to an Ivy. There is way more academic money out there than athletic.
