depends on ambient temperature:
non operational @90*F 150psi both sides
operational low side @90*F 20-35 psi
operational high side @90*F 290-280 psi

if your running 280-290 on a high side, you got issues.

Real world operational pressures will vary at idle anywhere from 25-40, high side shouldn't see more than 250 unless you have an obstruction. I wouldn't expect to see that close to 300psi unless your racing the engine or running a dual ac(front/rear).

I got those specs straight from the factory service manual.

real world i've never seen pressures that high on anything that was working properly without a dual AC system.

My neon, blowing 38-45deg on a 90deg day is 36on the low and 190-210 on the high :) at idle, at 3500rpm 24 on the low and about 250-260 on the high.
