So how much torque does it take to turn the engine over (using the PS nut)? If more than 37ft.lbs then nut would tighten. If less, then no affect on nut tightness.

Don't forget that the crank pulley is larger than the PS pulley. The torque required to turn the engine can be a little bit higher than 50Nm because of this. Like trying to start off on your bike in 1st vs. 7th gear.
