Im chasing down a small leak that developed while changing out my evap core. It wont hold vacuum for more than a few hours.

I have put a small charge of freon, and pressurized the rest with nitrogen. I am aware that static pressure is about 80 psi, but was wondering if I could pressure test at 150? 200? Whats the max?
