Even without further info I can suggest that the optimum for overall system design is going to be with a loop delta-T in the range of 20-30 F.  So at 225 hp is going to require 27 – 35 gpm for pure water, and about 37 – 50 gpm with 50/50 water/glycol mix.  Of course it is difficult to detmine ‘optimum’ heat exchanger design to go with it.  Lower flow/higher delta-T needs more exchanger area, which is determined by airflow requirements.  Steady 225 hp will need something around 6000 cfm air flow on a 90F day.

 

I measured pretty close to 50 gpm @ 6000 rpm on the dyno with no thermostat and unknown cooling loop pressure drop.  

 

FWIW,

I should be golden then.. the race mate products flow around 130-140 GPM according to their documentation. If they are accurate, and there is minimal restriction, there should be more than enough flow.
