Why would we expect that the two outlets from this pump would provide any more equal flow split than dividing the outlet from one pump outlet into two circuits?  Either way the flow is going to split in proportion to the pressure drop in each of the two loops.

Ken, let us know if you figure out which Toyota models use this pump.

Subject: [FlyRotary] water pump with 2 outlets

 

 

> I keep looking at all the successful, flying rotary engine airplanes that

are using evaporator cores and can't help but wonder if this is the hot

setup.  Just for everyones consideration, some Toyota's use a standalone

water pump that has 2 outlet ports.  These look to be about .7" in diameter

but I have not measured the size.  I can't help but consider using this pump

mounted 'low' and using an adapter like the guys using EWP's are using.

These 2 outlets from the water pump can be used to run 2 evaporators cores

in parallel without fighting with the uneven flow that most other setups

deal with.  Advantages are:

> 1.  LOW mounted water pump (what is the flow rating of this pump?)

> 2.  parrallel flow to 2 evaporator cores

> 3.  more even coolant distribution to the cores
