Honestly I think it depends on your fuel set up as a whole. Seethroughead is wanted to get up to 650 on pump which the 1050cc should be enough as long as he has the rails to go with it. (Although 580 to 600 may be a better number).

redondoaveb ran out of duty cycle but keep in mind he was running on e85 so takes more volume/fuel to get the same numbers that's why he needed bigger injectors and pumps.

I hit 650 with rails and the hellcat pump running 1300cc injectors at under 80% cycle.

Keep in mind you are be going to want to move volume over pressure. I feel like you shouldn't want the pumps fighting each other. But again depends on your setup as a whole unit
