Gave it a try on the crank pulley bolt on my RV8 which can be a pain especially as my car is an auto, and after a couple on minutes of screaming away, it came off.

Instructions say the peak torque is 180 nm.
Never ceases to amaze me how such things have been invented in my lifetime. I can remember the grief I had undoing a crank pulley fixing first time I did it - many years ago - on another engine, likely a BMC B series.
