Missed the part about you reducing the inlet. I'm no expert I only know that's really bad for any pump and there's no way it's pushing what it's rated for. I'll bet it's pulling all the watts though. So to find an equal pump to the flow you're probably pulling thru one inch pipe... You might not have to aim so high.
The restriction Might be making it noisier as well.
