Next up is to figure out what pump to use. I have it narrowed down to two pumps due to the factory pump being absurdly priced.
Davies Craig Electric Booster Pump Kits DC-9040 this flows 9.2 gpm.
Many use this pump in the LS swap world with no issue.
Or
Meziere Remote Electric Water Pumps WP136S this flows 20gpm.
I'm worried the davies craig won't flow enough by the time it completes the loop with the restrictions of the coolers. The hellcrate instructions call for recommended output of 45 L/min (12 gal/min) at 150 kPa (22 PSI).
What are your thoughts? Is 20gpm too much flow? Definitely don't want it passing through the heat exchanger to fast.
