I had gt pumps with my old returnless setup and my duty cycle was almost maxed at 600whp. I had a BAP on top of it for some safety buffer.
You could go bigger pumps but it won't run a nice as a return system. Fuel pressure isn't super steady with a big returnless system in our cars. Once I went return my pressure was perfectly flat and car ran so much smoother. Most noticeable at idle and part throttle cruising.
