One thing could be the calculated 75W is too high.
The heat capacity of the coolant used in the power calculations may not be right. I don't think the glycol additive (25%?) is being accounted for. Should be 10% ish lower I think. Could be wrong, pHaestus?
Doesn't account for all of it though (or even much of it actually), but it can not be the secondary losses, the power calculation has already accounted for them. (Tin-Tout)*Flowrate*Cap. H2O ? only measures the heat moving through the block.
