This is interesting and good data to have, I have a couple of questions
that
will help me interpret pump test results also.
1. If I remember right, you are using 3/4" hose to each core, with 3/4"
hose
back to a collector near the pump, is that correct?
That is correct.
2. Did the 30 degree drop manifest itself before or after you did the
modification and put in a thermostat? If before -- I would expect that it
also lowered your operating temperature of the engine, if after I would
suggest that the thermostat is doing its job and cutting the flow rate due
to
cooler weather, and keeping the outlet temp of the flow to the set point.
If
that is the case the performance during 90 degree weather will be very
interesting to observe.
It really didn't get cool outside until after I put in the thermostat, but I
think your observation is correct. The thermostat is reducing the radiator
flow. I have pre-threaded the bypass hole for a pipe plug in case I need to
pull the thermostat in hot weather.
