I have one on my SB18+OS91HZ. Compared with the stock one I'll say it has a bit more mid torque.

My setup as a lot of power, easy to tune and quite consistent to be an OS motor. Only problem I have is that bearings are lasting only 5 gallons. I'll start to use after run with this motor.

My ys 91sr-rr likes it on higher rpm. Seems to be less torque on low headspeeds.
