Highest thrust in 70mm EDF

Anyone know what motor and 70mm fan setup has the highest thrust for a 3s or 4s setup? I am in need of a motor fan combo that can produce around 1100grams or more static thrust without going over 45 amps if its possible. Not sure whats out there in the major power department.

Is this in an air frame or a bench number? From the manufacturer or something you measured?

To the OP,

I sort of doubt that you can get a system like you want with 48A draw if you want that thrust as measured in the airframe in a ground test (how I measure). I get about 2.125 lb @49A for the 3200kv eflite fan/motor as measured in the airframe on 4S. You will need to beat eflite's efficiency significantly.
