Think I may need twin pumps ?

[DuMaurier 7]

I am presently using the system 2D on a rotary engine thats soon going to be boosted to within an inch of its life . I have expanded the system a bit ,doubling up on the jets , now using a pair of 0.9mm ones , and a pair of accumulators (may add 2 more!!) , I am wondering if one RACE PUMP would be enough to quickly charge the system after injection events lasting less than 12 secs , or would a second pump be necessary . I use the car on the street mostly with occasional trips to the track.
