Let's see.

The max operating pressure for a standard cooker is approx 1.8bar absolute. With estimated safety factor of 1.5times the cooker will explode at 2.7bar absolute. Pressure cookers are stainless steel and have a screw-on lid. At the 2.7bar the steel treads on the lid will shear or bend. The lid is going to fly a fucking long way (scientifically speaking) one way or another at this pressure. It would be hard to get the pressure much higher because the lid will blow off. So that's my WAG. Wild Ass Guess.
