How to Spec an Oil Cooler

Evenin all.
Are there any golden rules for specifying an oil cooler?
I only ask as I won't be using the standard cooler off the bike (oil-cooled BMW HP2 Sport). Why is this I hear you ask!? Well, a) the BMW unit
is an expensive and complicated parallel consecutively-switched jobbie, and, b) I can't hope to replicate the air-flow of the bikes set-up
anyway.
So, I'll have to try and work out an alternative solution.
In all likelihood my cooler will be out of the air flow, and I'm prepared to run it with a fan if I have to.
All opinions welcome!

Do you really need one ?
My son put one on his skyline 500bhp and found the oil was not getting up to the recommended temp
Its just a thought
as you say all opinions welcome

Wise to fit an oil thermostat that way the oil will always be at the correct temperature.

My logic is... seeing as the bike had one, then yes. I could be wrong though... I frequently am!
It's only an air / oil cooled engine remember and it's been factory-tuned to within a smidge of it's design limits.

There's already a thermostat valve on the engine for the oil outlet. So is it therefore just a case of fitting as big a cooler as space allows
and letting it get on with it?

Fit a big one, drive around a bit ( read thrath it) if its not getting to hot then thrash it harder
