There's an Integra or two down here with 600 to the wheels on race fuel, and mid-4s on pump. Hatches tend to be about that as well. NY has some ridiculously powered <2l cars as well.
Miatas have been known to get into the 4s with the 1.8s...There's a 1.6 down here that makes 500rwhp with a 150 shot. Haven't seen that dyno, but it's rather well known.
Columbia at Speedclinic is supposedly awesome like that.
