Sometimes I miss the obvious. Used the Gates flow calculator
<http://www.gates.com/catalogs-and-resources/resources/repository/engineering-business-applications/pressure-drop>
and realised I had introduced an unnecessary pressure loss to my oil
circuit.
Before I get ridiculed, here is context. I live 500km from the most remote
city on earth. So quite often have to be resourceful with what's on hand or
wait forever for part deliveries. During the build I had just grabbed some
new hose & fittings from my farm workshop to hook up the oil cooler to the
engine, had every intention at the time to replace with lightweight hose &
fittings but over the build time just plain forgot. Thought I had the size
right but didn't count on so much loss with such low oil operating
pressures & flow. but still should've tagged those parts. So before I order
a new cooler, I'll try it with larger hose.
If I've used it correctly, I reckon I can maybe accept some pressure loss
through the cooler if I absolutely minimise it in the hose & fittings.
