I would expect a drop but what to?

Relief valve surely is lifted by pressure and is not necessarily RPM dependent. Also viscosity will be a factor as will temperature. How hot is hot?

Also as the relief valve is opposed by spring pressure it will vary infinitely.
Just my thoughts probably bollox as usual.
