Selecting nozzles is this wright
 

Water jets is selected by adding all injector cc then its 10 to 15% of that
if the fuel pressure and water pressure is the same.Turbos go with 10% and blowers go with 15% :?: :?:

Water pressure is much higher if you use aquamnist pump and jets.

You can assume that S/C will require more water and the engine is more loaded by spining the S/C, also most S/C don't have an intercooler.
