Ok guys I have been doing some series research on how to read compressor maps but i still am not 100% sure on how to read them. I have pretty much everything on the map figured out but still don't know quite how they work. Heres what I have as info on my car. Pressure ratio @8lbs of boost 1.54 airflow between 16-59lb/min. Please help me out how to read the compressor maps I don't understand exactly how they work.
