Didn't get to stretch it out yet. I did run it to 90 with ease and still pulling hard. I backed out because conditions were not exactly right. I'm not real comfortable with everything yet so didn't want to push it to the edge. I'll tell ya it's a Beast the acceleration is unreal. I'm impressed. I still had 25 lbs of water psi and plenty of rs left so I have alot o room to play with
