DIY Water Maker Question

I designed the water maker,(engine driven with belt), to run at or below 2k rpm. If I go over 2k it begins to draw a vacuum. If I increase the size of the supply pump, increase gpm, will this allow me to run at a higher rpm. The drive pulley is 4" and the pulley on the high pressure pump is 7". The pump max rpm is 1750

Take a look at the current edition of Good Old Boat. Add a Water Puppy boost pump.
