This may have inadequate variables, but looking for optimum Gallons Per Minute desired water pump flow for a 13B 2nd gen, at 6000 rpm but boosted to 250 hp max (realistic is 200-225, but I dont want to marginalize capacity). Assuming no more than 20 psi and no undue flow restrictions.
 
Any takers on the math?
 
Why: spec'ing a racemate direct drive water pump and alternator.. I intend to order in the next week and want to select the right one.. or the "most right" one.
 
Dave
