Thanks Ed.

But 185.85 seems pretty detailed for a SWAG.
Any chance you got it from Bill Shertz's tests (which I unfortunately can't find the posts about)?

What determines "Cp Coolant"?
Heat transfer efficiency from engine to water and water to rad?

From measuring the rims of the e-shaft pulley (122mm) and water pump pulley (112mm) it looks like the Renesis water pump runs a bit slower (factor 1.09 compared to your 1.18).

Should water flow be directly proportional to water pump RPM?

Sorry, Finn.

Hi Ed,
=C2=A0
From where did you get the 13B coolant flow numbers (Pump Factor)?
=C2=A0
I want to be certain that I have adequate coolant flow.
=C2=A0
Finn
=C2=A0
