max psi for an engine driven compressor?

does anyone know the max psi to run through a stock mazda ac pump? im using an ac compressor as my engine driven and need to know what psi to set it at

thanks

like a sanden|?

i honestly dont know what type it is, i just know that its a brand new factory ac pump from vatozone

i know people who push 300psi and to them all day long and no problems as long as you keep it oiled and such

yeah i def have an oiler hooked up to it, i just didnt want to push it too hard and end up frying it, i think im gonna go up to about 175 and stay safe with that
