Yes, outlet temperature of the block is lower, outlet temperature of the =
radiator is higher. Delta-T across the radiator is lower. Think of it =
this way, Q (heat transfer) is stable at some operating point. The =
excess heat from the engine is equal to the heat removed from the =
radiator. Ignore the heat transfer coefficient for the moment.=20
So Q for radiator =3D mass x (Tin-Tout) and Q for engine is mass x =
(Tout-Tin). Q and M is the same for both engine and radiator and Tin of =
=3D Tout of engine, likewise Tout of radiator =3D Tin of engine.
Obvious, right. So hold everything stable and increase flow rate. =
Obviously Tin-Tout must decrease as does Tout-Tin. The operating =
temperature will depend solely on the temperature drop across the =
radiator. If you and a lower operating temp at that Q you need a lower =
Tout of the radiator.=20
If you increase engine load and RPM, the mass flow rate increases with =
RPM, but not linearly since it=E2=80=99s a centrifugal pump. Slip gets =
worse with RPM. The high flow rate system has a lower delta-t across the =
engine, but also has a lower delta-t across the radiator. Temperature =
will likely climb higher than with a lower flow rate system (depending =
on where you measure it, but heat transfer rate is lower, so you might =
reach a point where it=E2=80=99s inadequate to meet the engine demand. =
then Tout climbs quickly and shit happens.=20

Changing pump speed didn't help either. The difference between radiator =
