All I can think of is your compressor is really loading the engine and it sounds like you're short cycling. How are your pressures? No help but mine doesn't do that. FYI: the air at my center vent was 34° at an OAT of 85° yesterday. I don't remember the pressures but it seems like it was going to around 230 on the high side.

You have most likely over-charged the system and the pressure-relief valve is popping off.

NEVER EVER add a/c coolant without a set of known-good pressure gauges.

Some things that can be destroyed by overfilling and over press-ing the system include:

Everything.

Maybe buy a compressor? Or have it checked out by someone that knows what they're doing? Not trying to ding you but adding refridgerant when anything goes wrong with the AC is not the solution. Spend some money and get it checked out.
