All pumps on the market are quoting "dead-headed" pressure. Totally meaningless. As soon as the spray starts, the pressure will drop. Higher "dead head" pressure setting will drop much faster than a lower "dead-head" pressure setting.

Let's take 1600cc/min as Maximum flow (0.9mm(M5.3) nozzle) for a 4cylinder engine :
A - 1 Pump = 1600cc @ 160psi = (400cc x 4 nozzles)
Good for mixing 75% pump fuel and 25% Water/Methanol
B - 2 Parrallel Pumps = 3200cc @ 160psi = (800cc x 4 nozzles)
Good for mixing 50% pump fuel and 50% Water/Methanol
C - 2 Series Pumps = 1600cc @ 320psi = (400cc x 4 nozzles)
BEST for mixing 75% pump fuel and 25% Water/Methanol. SUPER FINE MIST
D - 3 Parallel Pumps = 4800cc @ 160psi = (1200cc x 4 nozzles)
Good for mixing 25% pump fuel and 75% Water/Methanol
E - 2 Parrallel + 2 Series Pumps = 3200cc @ 320psi = (800cc x 4 nozzles)
BEST for mixing 50% pump fuel and 50% Water/Methanol. SUPER FINE MIST
F - 4 Parallel Pumps = 6400cc @ 160psi = (1600cc x 4 nozzles)
BEST for operating engine @ 100% Water/Methanol injection
Calculating Fuel flow for 400Bhp @ 1.2 BSFC 100% Methanol = 1260cc/min x 4nozzles. Using 25/75 Water/Meth, one should compensate for water flow and Setup F configuration of 4 Parrallel Pumps would be needed.
Calculating Horsepower loss per WATT taking account pump is operating at 14Volts x 10Amps
1 Pump = 140Watt = 0.19Hp loss
2 Pump = 280Watt = 0.38Hp loss
3 Pump = 420Watt = 0.57Hp loss
4 Pump = 560Watt = 0.75Hp loss
Maximum of 1Hp loss @ 100% Meth fuel injection. Is it worth it ?
What is your point of view Richard ?
