Aeromotive dual phantom in take system?

[tiddlar]

Been looking at the dual phantom in take set up.
Question 1: would one pump be enough to run?
Question 2: when the gas is to the floor can the second pump kick in? The time it takes for the second pump to kick in will that effect the motor?

This picture has it with both pumps running, if I’m only going to use one pump, (most of the time) wouldn’t the pressure be affected ? So would changing an size prior to filter help with pressure?

Or should I have both pumps running at once? Spoke to aeromotive tech staff mentioned since one pump will be running all the time an size prior to filter should be changed
Him and I got into it, he was trying to make a sale. Aeromotive was 2200 and jegs 1685. He refused to e mail me parts numbers ... any input appreciated thanks gentlmen
The motor is an RHS502 ls 869 hp naturally aspirated with direct port nitrous 200 shot.
