I have recently installed an ac compressor in Belta 1.3 by Bashir Autos in Karachi. The cooling is fine but the engine performance is not the same anymore especially at lower speeds or when i am accelerating from 0. I can feel the engine is really working hard but at high RPM the performance is mor or less the same. I did speak to their owner and he told me that there will be a difference in performance cuz the one that is installed in my car is a ''Magnet Wala'' compressor whereas the stock compressors are usually equipped with a sensor.
I would like to know anyone who has any experience with these compressors and have they felt the performance issues what i am experiencing rite now. Cheers
